Why Predictive Maintenance is More Profitable than Reactive Maintenance

Regular maintenance is needed to keep the equipment in your facility operating normally. All machinery has a design lifespan, and your goal is to extend this as long as possible, while maintaining optimal production levels. How you go about the maintenance matters, from routine checks to repairing the damaged component parts?all before the whole unit needs to be tossed away and a new one purchased and installed. Here, we will break down the different approaches used, and show you why more industries and businesses are turning to proactive maintenance modes as opposed to the traditional reactive approaches for their?field service operations.?

Reactive Maintenance: A wait and see game

Here, you basically wait for a problem to occur, then fix it. It’s also commonly referred to as a “Run-to-Failure” approach, where you operate the machines and systems until they break. Repairs are then carried out, restoring it to operational condition.?

At face value, it appears cost-effective, but the reality on the ground is far much different. Sure, when the equipment is new, you can expect minimal cases of maintenance. During this time, there?ll be money saved. However, as time progresses there?ll be increased wear, making reliance on a reactive maintenance approach a costly endeavour. The breakdowns are more frequent, and inconsistent as well. Unplanned expenses increase operational costs, and there will be lost productivity during the periods in which the affected machinery won’t be in operation.?

While reactive maintenance makes sense when you’re changing a faulty light bulb at home, things are more complicated when it comes to dealing with machinery in industries, or for those managing multiple residential and commercial properties. For the light bulb, it’s easier to replace it, and failure doesn’t have a ripple effect on the rest of the structures in the household. For industries, each time there is equipment failure, you end up with downtime, production can grind to a halt, and there will be increased environmental risks during equipment start-up and shutdown. If spare parts are not readily available, there will be logistical hurdles as you rush the shipping to get the component parts to the facility. Add this to overworked clients in a bit to complete the repair and to make up for lost hours and delayed customer orders.

For field service companies, more time ends up being spent. After all, there?s the need of knowing which parts needed to be attended to, where they are, and when the servicing is required. Even when you have a planned-out schedule, emergency repairs that are required will force you to immediately make changes. These ramps up the cots, affecting your operations and leading to higher bills for your client. These inconveniences have contributed to the increased reliance on?field service management platforms that leverage on data analytics and IoT to reduce the repair costs, optimise maintenance schedules, and?reduce unnecessary downtimes?for the clients.

Waiting for the machinery to break down actually shortens the lifespan of the unit, leading to more replacements being required. Since the machinery is expected to get damaged much sooner, you also need to have a large inventory of spare parts. What’s more, the damages that result will be likely to necessitate more extensive repairs that would have been needed if the machinery had not been run to failure.?

Pros of reactive maintenance

Less staff required.
Less time is spent on preparation.

Cons of reactive maintenance

Increased downtime during machine failure.
More overtime is taken up when conducting repairs.
Increased expenses for purchasing and storing spare parts.?
Frequent equipment replacement, driving up costs.?

This ?If it ain’t broke, don’t fix it? approach leads to hefty repair and replacement bills. A different maintenance strategy is required to minimise costs. Proactive models come into focus. Before we delve into predictive maintenance, let’s look at the preventive approach.?

Preventive Maintenance: Sticking to a timetable

Here, maintenance tasks are carried out on a planned routine?like how you change your vehicle?s engine oil after hitting a specific number of kilometres. These tasks are planned in intervals, based on specific triggers?like a period of time, or when certain thresholds are recorded by the meters. Lubrication, carrying out filter changes, and the like will result in the equipment operating more efficiently for a longer duration of time. While it doesn’t completely stop catastrophic failures from occurring, it does reduce the number of failures that occur. This translates to capital savings.??

The Middle Ground? Merits And Demerits Of Preventive Maintenance

This periodic checking is a step above the reactive maintenance, given that it increases the lifespan of the asset, and makes it more reliable. It also leads to a reduced downtime, thus positively affecting your company?s productivity. Usually, an 80/20 approach is adopted,?drawing from Pareto’s Principle. This means that by spending 80% of time and effort on planned and preventive maintenance, then reactive maintenance for those unexpected failures that pop up will only occur 20% of the time. Sure, it doesn’t always come to an exact 80/20 ratio, but it does help in directing the maintenance efforts of a company, and reducing the expenses that go into it.?

Note that there will need to be a significant investment?especially of time, in order to plan a preventive maintenance strategy, plus the preparation and delegation of tasks. However, the efforts are more cost effective than waiting for your systems and machinery to fail in order to conduct repairs. In fact, according to the US Dept. of Energy, a company can save between 12-18 % when using a preventive maintenance approach compared to reactive maintenance.

While it is better than the purely reactive approach, there are still drawbacks to this process. For instance, asset failure will still be likely to occur, and there will be the aspect of time and resource wastage when performing unneeded maintenance, especially when technicians have to travel to different sites out in the field. There is also the risk of incidental damage to machine components when the unneeded checks and repairs are being carried out, leading to extra costs being incurred.

We can now up the ante with predictive maintenance. Let’s look at what it has to offer:

Predictive Maintenance: See it before it happens

This builds on preventive maintenance, using data analytics to smooth the process, reduce wastage, and make it more cost effective. Here, the maintenance is conducted by relying on trends observed using data collected from the equipment in question, such as through vibration analysis, energy consumption, oil analysis and thermal imaging. This data is then taken through predictive algorithms that show trends and point out when the equipment will need maintenance. You get to see unhealthy trends like excessive vibration of the equipment, decreasing fuel efficiency, lubrication degradation, and their impact on your production capacities. Before the conditions breach the predetermined parameters of the equipment’s normal operating standards, the affected equipment is repaired or the damaged components replaced.??

Basically, maintenance is scheduled before operational or mechanical conditions demand it. Damage to equipment can be prevented by attending to the affected parts after observing a decrease in performance at the onset?instead of waiting for the damage to be extensive?which would have resulted in system failure. Using?data-driven?field service job management software will help you to automate your work and optimise schedules, informing you about possible future failures.

Sensors used record the condition of the equipment in real time. This information is then analysed, showing the current and future operational capabilities of the equipment. System degradation is detected quickly, and steps can be taken to rectify it before further deterioration occurs. This approach optimises operational efficiency. Firstly, it drastically reduces total equipment failure?coming close to eliminating it, extending the lifespan of the machinery and slashing replacement costs. You can have an orderly timetable for your maintenance sessions, and buy the equipment needed for the repairs. Speaking of which, this approach minimises inventory especially with regards to the spare parts, as you will be able to note the specific units needed beforehand and plan for them, instead of casting a wide net and stockpiling spare parts for repairs that may or may not be required. Repair tasks can be more accurately scheduled, minimising time wasted on unneeded maintenance.??

Preventive vs Predictive Maintenance?

How is predictive different from preventive maintenance? For starters, it bases the need for maintenance on the actual condition of the equipment, instead of a predetermined schedule. Take the oil-change on cars for instance. With the preventive model, the oil may be changed after every 5000?7500 km. Here, this change is necessitated because of the runtime. One doesn’t look at the performance capability and actual condition of the oil. It is simply changed because “it is now time to change it“. However, with the predictive maintenance approach, the car owner would ideally analyse the condition of the oil at regular intervals- looking at aspects like its lubrication properties. They would then determine if they can continue using the same oil, and extend the duration required before the next oil change, like by another 3000 kilometres. Perhaps due to the conditions in which the car had been driven, or environmental concerns, the oil may be required to be changed much sooner in order to protect the component parts with fresh new lubricant. In the long run, the car owner will make savings. The US Dept. of Energy report also shows that you get 8-12% more cost savings with the predictive approach compared to relying on preventive maintenance programs. Certainly, it is already far much more effective compared to the reactive model.?

Pros of Predictive Maintenance

Increases the asset lifespan.
Decreases equipment downtime.
Decreases costs on spare parts and labour.
Improves worker safety, which has the welcome benefit of increasing employee morale.
Optimising the operation of the equipment used leads to energy savings.
Increased plant reliability.

Cons of Predictive Maintenance

Initial capital costs included in acquiring and setting up diagnostic equipment.
Investment required in training the employees to effectively use the predictive maintenance technology adopted by the company.

The pros of this approach outweigh the cons.?Independent surveys on industrial average savings?after implementing a predictive maintenance program showed that firms eliminated asset breakdown by 70-75%, boosted production by 20-25%, and reduced maintenance costs by 25-30%. Its ROI was an average of 10 times, making it a worthy investment.

ESOS ? Why we must have it

The 9,000 big UK businesses directly affected by the new Energy Saving Opportunity Scheme could save UK?250 million between them, or an average UK?27,000 each, if they reduced electricity consumption by just 1%. The total amount is equal to the output of five power stations, at a time when Britain?s grid is under strain.
On 26 November 2014, UK Energy and Climate Change Secretary Ed Davey met with over 100 opinion makers from businesses, charities and universities at the Institute of Directors. The gist of what he presented was:

?Britain?s big firms are spending around ?2.8 billion extra each year on inefficient energy technologies ? the equivalent output of nearly five power stations;

Now is the time to seize the opportunity with ESOS ? and organisations up and down the country are already gearing up to make changes to save energy, save money and save the environment.

If business did what business is supposed to do [that is innovate to make money] and act and invest, it will save ? and that’s the bottom line.?

The environmental benefits are as important although EcoVaro agrees with Ed Davey for taking a pecuniary approach. Businesses above the threshold of 250 staff and a balance sheet of UK?34 million would have not achieved their status unless they spent their money wisely.
The discussion panel included Rhian Kelly (Director of Business Environment at CBI), and Paul Ekins (Director UCL Institute for Sustainable Resources & Deputy Director of the UK Energy Research Centre). Hugh Jones, Managing Director, Advisory at the Carbon Trust responded to Ed Davey?s remarks by commenting:

?At the Carbon Trust we have already engaged with hundreds of businesses on ESOS, helping to explain how they can achieve compliance while also making significant energy savings and cutting carbon.
Businesses often aren’t aware of opportunities in energy efficiency, or they don’t realise how attractive the paybacks can be. By requiring companies to understand exactly how they can make cost-effective investment in energy efficiency, they are far more likely to take action.
From the interest we have seen so far we expect ESOS to benefit British business by helping companies to reduce overheads and increase competitiveness.

The UK?s Energy Saving Opportunity Scheme ESOS is a gold mine of opportunities for big business, the environment and the population that breathes the air. Measurement of critical energy throughputs is the beginning of the process. EcoVaro is standing by to help you convert your data to meaningful information.

Why integrating your Field Service Management with IoT Applications makes sense

Your customers want a smooth experience when hiring your services. Whether there are pests that have run amok in their homes and you have been called in to exterminate them, there is a leak in the pipes and your plumbing repair business is the go-to for repairs, you’re in charge of a cleaning business with clients spanning across the residential and commercial niches, or even a locksmith making new installations and providing aftercare for their clients ? it is vital to make the process as hassle-free as possible for your customer. The priority is getting the job done in time, and to quality standards. On the other hand, your mobile workers need access to complete and accurate data to approach the task more proactively, get it done right, and increase the rate of first-time fixes.

When you have multiple clients and a huge workforce, things can get messy with all the paperwork involved. Preparing documents and reports, keying in the data, keeping track of your mobile employees, following up on current jobs and scheduling new appointments ? the workload can put a strain on your staff. Field service scheduling software like FieldElite come in to keep your central office staff abreast with all customer details, sending alerts when new issues arise. These are then relayed to the appropriate technician for the situation to be taken care of at the earliest possible time ? directing the right employee to the customer based on the skill-set availability and location. While field service job management software, by itself, is a powerful solution, you can crank things up a notch by having a system that integrates IoT into its operations.

Powering Field Service Scheduling Software Systems With IoT

FSM gives maintenance firms, distributors, manufacturers and other service businesses an interactive platform that optimises the workflow. From the customers booking maintenance work, office staff tracking operations right from their desk, workers interacting with it while on-ground through the mobile app, to the billing and invoicing ? it is all handled through the same system. IoT applications can boost this becoming a critical tool to show the field managers about the precise locations where attention is needed, for accurate worker and job scheduling and improved customer satisfaction. What if you could also have features like auto-scheduling coming on board? Let’s delve deeper into what it means for your FSM system.

Benefits Of Using Service Management Software With IoT Solutions

Its impact of IoT on field management is seen in the transformation of maintenance data into proactive service actions. Research by Gartner shows that in 2020 there will be over 20 billion connected devices, making the reach of IoT really vast. This will fuel the field management industry, unlocking more potential with the mobile workers interacting in real-time with their equipment and headquarters. This speeds up response time to service requests and transforms interoperability across the different devices.

???????? All-round access

The interaction with IoT benefits the technicians, managers, and customers themselves. For instance, while the worker on ground interacts with the FieldElite mobile app, the office staff at headquarters will be engaging them via browser on their smart devices, and even the client gets access to the system through the customer portal.

???????? Linking your different business operations

It doesn’t stop there. Integrating the mobile service management software to the IoT facilitates inventory management, automobile tracking, and even automates accounting, invoicing, and other internal processes of the business, giving you more visibility over your field assets and operations. Here, the sensors that have been enabled in the network will notify you of damaged equipment, and go further to route and dispatch the technician who is most suited to go on-site and repair it.

???????? Nip things in the bud ? A proactive approach

Updates from sensors on the remote equipment are sent over a dedicated network. This is intelligently interpreted by the IoT platform to decide the next course of action, depending on a predefined set of rules. This course of action can be assigning and dispatching the technician through the FieldElite app to fix the equipment before permanent damage occurs. This whole process is automatic, shifting the company from a reactive mode of operations to a proactive and preventative model, resulting in better utilisation of assets.

???????? Minimise time wastage

Less time is spent going checking for flaws in the systems. Take management at a wastewater treatment plant for instance. Simply place IoT sensors on the different pumps, mortars and valves to give you this data. In case of leaks or damage, the appropriate operator is alerted, taking away the need for manual monitoring. Monitoring is done remotely. Hazardous situations such as in the oil and gas industry where workers are faced with issues like flare stacks are handled better, where the IoT sensors minimise downtime and ensure that only necessary visits to the plat equipment are done.

???????? Interactions at the palm of your hand

The field service workers are also equipped with effective communications through aspects like the chat feature on the mobile app, and reporting abilities where they can make notes, take photos and relay this to the headquarters during the course of the job. Information on the system is readily available to the customer and future technicians who will be handling jobs at the facility.

How does the FSM work with other systems? FieldElite’s core role is to manage the mobile workforce. How do you keep track of the sensors of the different equipment, in order to know when maintenance is needed?

Enter ecoVaro: IoT In Energy Management

The 2018-2025 Global Building Energy Management System Analysis and Forecast showed energy consumption in residential buildings accounts for close to 40% of the world’s energy consumption.? Commercial buildings like shopping malls, hospitals, retail stores and hotels take 30%. IoT tools aid in collecting and analysing the real-time data consumption in these falsities, to improve maintenance and reduce down times. It’s a holistic view that is achieved through a network of smart devices monitoring the ventilation, humidity, air-conditioning and lighting systems.

Home automation tools like smart thermostats and bulbs are already becoming popular. Here, they bring savings to the consumers without them having to use up much effort. For broader energy management, these systems will include units like sensors, controls, meters, data analytics tools, and user-friendly applications that the consumers access all this from. It cuts across the board, from households and commercial establishments, to utility firms and government bodies keen on effectively monitoring and managing their energy resources. Industrial and commercial users need data analytics tools to maximise their productivity and reduce costs, while residents in households want to reduce their monthly bills and take a more proactive role in their energy management.

From Smart Devices To Accurate Loggers

The first step in saving energy is cutting down wastage. Smart light, humidity, temperature and air conditioning controls come in to maintain optimal indoor conditions. Lighting units, smart thermostats, sensor-based HVAC control systems are part of the IoT, taking centre stage in automatically maintaining the perfect indoor environment that will keep the building?s energy use at optimum levels. They have been designed with different sensors that check the humidity, light, motion and even CO₂ levels, dynamically adjusting the conditions in the facility. Here, you have situations like smart lights dimming when there is more daylight getting into the room, and then automatically turning off when people leave the room. The smart thermostats can precool the indoor space before the day gets warmer, so that during that scorching midday sun there will be less energy spent by the HVCA to bring down the heat levels.

The whole set up ? from the LED lights adjusting to user preferences and routines, learning thermostats that reduce consumption during peak load times, sensors and data analytics that give the user more control over their consumption, creates a smart energy infrastructure, be it in homes or industrial spaces, from retail stores and factories, to entire cities. This is all geared at cutting down energy costs, with the systems automatically adjusting the building?s lighting, temperature and ventilation, to reduce the energy consumption without compromising the comfort of the building?s occupants. LEED bulbs already record 20% lower maintenance costs than the typical commercial buildings.

Adopting IoT Applications For Your EMS System

How can you take advantage of this? With the EMS loggers, you monitor your facility’s consummation in real-time. Platforms like ecoVaro enable both the utility companies and end-users to access this data. The utility firms will be in a position to tailor the power supply in response to changing demand and also adjust their pricing. The end-users, on the other hand, will be in a position to control their usage at a granular level ? responding to changing environmental conditions, power consumption, and reducing energy waste.

There are also those appliances that come with sensors, from boilers in the household, to heavy production machinery in industries. The EMS systems allow you to continuously monitor the load on the sensor-enabled assets, predict when overheating will occur and pinpoint risks of outages or damage on the line. Maintenance can then be immediately carried out to vent damages to the equipment. That way components like motors are protected from damages that would have ended up costing the firm lots of funds to replace. The data analytics from the EMS platforms enable the energy manager to strike that balance to optimise performance and reduce wear, thus prolonging the life of the equipment.

Even the heavy hitters in the energy sector get to benefit from the IoT. Take power production for instance. When you’re dealing with stations, solar farms and wind fields ? as they provide that much-needed power, they also consume energy and need plenty of maintenance. These are resource-heavy stations and as a manager, you want to keep a close eye on things. This involves a complex approach, from the sensors at the facilities, data analytics, to predictive maintenance. EMS software comes in to continuously monitor the equipment and wiring through the sensors. This enables you to prevent issues like overloads, and ensure that a balanced load is maintained on the line. The EMS goes a step further by enabling you to undertake predictive maintenance, for the timely repair of the equipment on the power grid, minimising accidents, preventing blackouts, and averting the costly down times.

Electricity utilities connecting their power plants and grids to available IoT solution networks get to be more transparent to their consumers, by showing them where the energy they use comes from. This empowers the consumers with the information needed to select the cleanest energy source during that period, which is particularly beneficial for those keen on adopting greener practices. For instance, you can have a system monitoring a network of grids, and dynamically shifting to power sources that have the least amount of emissions at the moment ? what’s gaining popularity as “automated emission reduction”. These lead to utility firms that produce clean energy getting more consumers and growing their revenue base.

Field And Energy Management: How FieldElite and ecoVaro Work Together Through IoT

So, on one hand, you have the energy managers following up on the consumption trends at their facilities, keeping an eye on their equipment.? On the other hand, you have field workers needed to carry out repair and maintenance works at different locations.? How do you join them together to ensure a seamless flow of operations?? The IoT.

This can be seen with ecoVaro and Field Elite interaction. Here, you have two independent systems that are interlinked through the internet and secure cloud systems, bringing more convenience on board for the users.

Picture this: Loggers collecting data from the meters and sensors on-site detect an anomaly, which you will immediately be able to view through the ecoVaro platform. This can be a myriad of issues, from plumbing to electrical systems that need to be worked on, and they are at multiple locations. How do you get them resolved? Dispatch your technicians through FieldElite.

Here’s a snapshot of how this works:

This way, you get to optimise your operations and cut down on coasts ? taking advantage of the data analytics tools brought to you by ecoVaro, and streamlining your workflow through FieldElite. IoT powered workforce and energy management systems thus become key in reducing operational expenses, scheduling repairs and maintenance, and planning for peak hours

Accessing real-time data has the welcome benefit of cutting down on the hours spent on energy management processes. Jobs like meter reading that would have taken lots of time are handled by the system. When it comes to field management, operational efficiency is increased by taking away the manual processes involved with all the paperwork.? The sensors monitored via ecoVaro alert the field service manager about equipment that needs to be checked, and FieldElite shows the field manager issues that are on queue to be resolved. In both cases, you get accurate data that will inform the decisions made ? from the maintenance measures required, to scheduling the jobs for the technicians to handle them. It’s a win-win situation.?

Building Blocks For A Brighter Tomorrow

What’s more, this sets you up for the future. Adopting IoT solutions for your field and energy management operations will score you higher ROIs going forward. The global community is working towards enhancing the efficiency of its operations and putting in place sustainable practices in line with their Social Corporate Responsibility (CSR). This is from service providers like plumbing and electrical repair businesses, to utility firms and power generation plants. Lighting systems, homes, office buildings, factories, communities, transportation and whole cites are getting connected through the internet and more control done via smart devices. This is further accelerated by cloud systems enabling real-time, reliable and secure access to the information. By incorporating these setups into your business structure, you will gain a competitive advantage in your niche. After all, we’re still in the early stages of IoT across the industries.

Knowing the Caveats in Cloud Computing

Cloud computing has become such a buzzword in business circles today that many organisations both small and large, are quick to jump on the cloud bandwagon – sometimes a little too hastily.

Yes, the benefits of the cloud are numerous: reduced infrastructure costs, improved performance, faster time-to-market, capability to develop more applications, lower IT staff expenses; you get the picture. But contrary to what many may be expecting or have been led to believe, cloud computing is not without its share of drawbacks, especially for smaller organisations who have limited knowledge to go on with.

So before businesses move to the cloud, it pays to learn a little more about the caveats that could meet them along the way. Here are some tips to getting started with cloud computing as a small business consumer.

Know your cloud. As with anything else, knowledge is always key. Because it is a relatively new tool in IT, it’s not surprising that there is some confusion about the term cloud computing among many business owners and even CIOs. According to the document The NIST Definition of Cloud Computing, cloud computing has five essential characteristics, three basic service models (Saas, Paas and Iaas), and four deployment models (public, community, private and hybrid).

The first thing organisations should do is make a review of their operations and evaluate if they really need a cloud service. If they would indeed benefit from cloud computing, the next steps would be deciding on the service model that would best fit the organisation and choosing the right cloud service provider. These factors are particularly important when you consider data security and compliance issues.

Read the fine print. Before entering into a contract with a cloud provider, businesses should first ensure that the responsibilities for both parties are well-defined, and if the cloud vendor has the vital mechanisms in place for contingency measures. For instance, how does the provider intend to carry out backup and data retrieval operations? Is there assurance that the business’ critical data and systems will be accessible at all times? And if not, how soon can the data be available in case of a temporary shutdown of the cloud?

Also, what if either the company or the cloud provider stops operations or goes bankrupt? It should be clear from the get go that the data remains the sole property of the consumer or company subscribing to the cloud.

As you can see, there are various concerns that need to be addressed closely before any agreement is finalised. While these details are usually found in the Service Level Agreements (SLAs) of most outsourcing and servicing contracts, unfortunately, the same cannot be said of cloud contracts.

Be aware of possible unforeseen costs. The ability of smaller companies to avail of computing resources on a scalable, pay-as-you-go model is one of the biggest selling points of cloud computing. But there’s also an inherent risk here: the possibility of runaway costs. Rather than allowing significant cost savings, small businesses could end up with a bill that’s bound to blow a big hole in their budget.

Take for example the case of a software company cited on InformationWeek.com to illustrate this point. The 250-server cluster the company rented from a cloud provider was inadvertently left turned on by the testing team over the weekend. As a result, their usual $2,300 bill ballooned to a whopping $23,400 over the course of one weekend.

Of course, in all likelihood, this isn’t going to happen to every small and midsize enterprise that shifts to the cloud. However, this should alert business owners, finance executives, and CEOs to look beyond the perceived savings and identify potential sources of unexpected costs. What may start as a fixed rate scheme for on-demand computing resources, may end up becoming a complex pricing puzzle as the needs of the business grow, or simply because of human error as the example above shows.

The caveats we’ve listed here are among the most crucial ones that soon-to-be cloud adopters need to keep in mind. But should these be reasons enough for businesses to stop pursuing a cloud strategy? Most definitely not. Armed with the right information, cloud computing is still the fastest and most effective way for many small enterprises to get the business off the ground with the lowest start-up costs.
