How Mid-South Metallurgical cut Energy Use by 22%

Mid-South in Murfreesboro, Tennessee operates a high-energy plant providing precision heat treatments for high-speed tools – and also metal annealing and straightening services. This was a great business to be in before the energy crisis struck. That was about the same time the 2009 recession arrived. In no time at all the market was down 30%.

Investors had a pile of capital sunk into Mid-South?s three facilities spread across 21,000 square feet (2,000 square meters) of enclosed space. Within them, a number of twenty-five horsepower compressors plus a variety of electric, vacuum and atmospheric furnaces pumped out heat 27/7, 52 weeks a year. After the company called in the U.S. Department of Energy for assistance, several possibilities presented.

Insulate the Barium Chloride Salt Baths

The barium chloride salt baths used in the heat treatment process and operating at 1600?F (870?C) were a natural choice, since they could not be cooled below 1200?F (650?C) when out of use without hardening the barium chloride and clogging up the system. The amount of energy taken to prevent this came down considerably after they covered and insulated them. The recurring annual electricity saving was $53,000.

Manage Electrical Demand & Power

The utility delivers 480 volts of power to the three plants that between them consume between 825- and 875-kilowatt hours depending on the season. Prior to the energy crisis Mid-South Metallurgical regarded this level of consumption as a given. Following on the Department of Energy survey the company replaced the laminar flow burner tips with cyclonic burner ones, and implemented a number of other modifications to enhance thermal efficiency further. The overall natural gas reduction was 20%.

Implement Large Scale Site Lighting Upgrade

The 24/7 nature of the business makes lighting costs a significant factor. Prior to the energy upgrade this came from 44 older-type 400-watt metal halide fixtures. By replacing these with 88 x 8-foot (2.5 meter) fluorescent fittings Mid-South lowered maintenance and operating costs by 52%

The Mid-South Metallurgical Trophy Cabinet

These three improvements cut energy use by 22%, reduced peak electrical demand by 21% and brought total energy costs down 18%. Mid-South continues to monitor energy consumption at each strategic point, as it continues to seek out even greater energy efficiency in conjunction with its people.

A Small External Enterprise Development Team is Cheaper than Your Own

Time is money in the application development business. We have to get to market sooner so someone else does not gazump us, and pip us at the post. We increase the likelihood of this with every delay. Moreover, the longer your in-house team takes to get you through the swamp, the higher the project cost to you.

Of course, in theory this should not be the case. Why bring in a team from outside, and pay more to support their corporate structure? Even going for a contract micro team ought not to make financial sense, because we have to fund their mark-up and their profit taking. Our common sense tells us that this is crazy. But, hold that thought for a minute. What would you say if a small external enterprise development team was actually cheaper? To achieve that, they would have to work faster too.

The costs of an Enterprise Internal Development Team

Even if you were able to keep your own team fully occupied ? which is unlikely in the long term ? having your own digital talent pool works out expensive when you factor in the total cost. Your difficulties begin with the hiring process, especially if you do not fully understand the project topic, and have to subcontract the hiring task.

If you decide to attempt this yourself, your learning curve could push out the project completion date. Whichever way you decide to go, you are up for paying advertising, orientation training, technical upskilling, travel expenses, and salaries all of which are going to rob your time. Moreover, a wrong recruitment decision would cost three times the new employee?s annual salary, and there is no sign of that changing.

But that is not all, not all by far. If want your in-house team to keep their work files in the office, then you are going to have to buy them laptops, plus extra screens so they can keep track of what they are doing. Those laptops are going to need desks, and those employees, chairs to sit in. Plus, you are going to need expensive workspace with good security for your team?s base.

If we really wanted to lay it on, we would add software / cloud costs, telephony, internet access, and ongoing technical training to the growing pile. We did a quick scan on PayScale. The median salary of a computer programmer in Ireland is ?38,000 per year and that is just the beginning. If you need a program manager for your computer software, their salary will be almost double that at ?65,000 annually.

Advantages of R&D outsourcing

The case for a small externally sourced enterprise development team revolves around the opportunity cost ? or loss to put in bluntly ? of hiring your own specialist staff for projects. If you own a smaller business with up to 100 people, you are going to have to find work for idle digital fingers, after you roll out your in-house enterprise project. If you do not, you head down the road towards owning a dysfunctional team lacking a core, shared objective to drive them forward.

Compared to this potential extravagance, hiring a small external enterprise development team on an as-needed basis makes far more sense. Using a good service provider as a ?convenience store? drives enterprise development costs down through the floor, relative to having your own permanent team. Moreover, the major savings that arise are in your hands and free to deploy as opportunities arise. A successful business is quick and nimble, with cash flow on tap for R & D.

What Heijunka is & How it Smooths Call Centre Production

The Japanese word Heijunka, pronounced hi-JUNE-kuh means ?levelling? in the sense of balancing workflows. It helps lean organizations shift priorities in the face of fluctuating customer demand. The goal is to have the entire operation working at the same pace throughout, by continuously adjusting the balance between predictability, flexibility, and stability to level out demand.

Henry Ford turned the American motor manufacturing industry upside down by mass-producing his iconic black motor cars on two separate production lines. In this photograph, body shells manufactured upstairs come down a ramp and drop onto a procession of cars almost ready to roll in 1913.

Smoothing Production in the Call Centre Industry

Call Centres work best in small teams, each with a supervisor to take over complex conversations. In the past, these tended to operate in silos with each group in semi-isolation representing a different set of clients. Calls came through to operators the instant the previous ones concluded. By the law of averages, inevitably one had more workload than the rest at a particular point in time as per this example.

Modern telecoms technology makes it possible to switch incoming lines to different call centre teams, provided these are multi-skilled. A central operator controls this manually by observing imbalanced workflows on a visual system called a Heijunka Box. The following example comes from a different industry, and highlights how eight teams share uneven demand for six products.

This departure from building handmade automobiles allowed Henry to move his workforce around to eliminate bottlenecks. For example, if rolls of seat leather arrived late he could send extra hands upstairs to speed up the work there, while simultaneously slowing chassis production. Ford had the further advantage of a virtual monopoly in the affordable car market. He made his cars at the rate that suited him best, with waiting lists extending for months.

A Modern, More Flexible Approach

Forces of open competition and the Six Sigma drive for as-close-to-zero defects dictates a more flexible approach, as embodied in this image published by the Six Sigma organisation. This represents an ideal state. In reality, one force usually has greater influence, for example decreasing stability enforces a more flexible approach.

Years ago, Japanese car manufacturer Toyota moved away from batching in favour of a more customer-centric approach, whereby buyers could customise orders from options held in stock for different variations of the same basic model. The most effective approach lies somewhere between Henry Ford?s inflexibility and Toyota?s openness, subject to the circumstances at the moment.

A Worked Factory Example

The following diagram suggests a practical Heijunka application in a factory producing three colours of identical hats. There are two machines for each option, one or both of which may be running. In the event of a large order for say blue hats, the company has the option of shifting some blue raw material to the red and green lines so to have the entire operation working at a similar rate.

Predictability, Flexibility, and Stability at Call Centre Service

The rate of incoming calls is a moving average characterised by spikes in demand. Since the caller has no knowledge whether high activity advisories are genuine, it is important to service them as quickly as possible. Lean process engineering provides technology to facilitate flexibility. Depending on individual circumstances, each call centre may have its own definition of what constitutes an acceptably stable situation.

Maturing Into CMMI

 

In all likelihood, the reason why you landed on this page was because you were seeking CMMI experts to help you meet the demands of a growing number of potential clients who require CMMI compliance.

Whether or not you’re here for that reason, you might want to know why CMMI or Capability Maturity Model Integration is steadily becoming a common denominator among highly successful software and engineering development companies. If you stay for a while, we can show you how CMMI can substantially increase your organisation’s chances of:

  • reducing development costs;
  • acquiring new customers and retaining old ones;
  • beating deadlines;
  • bringing down development time;
  • increasing the overall quality of your products and services; and
  • improving the level of satisfaction of customers, employees, and all other stakeholders.

Surely, no organisation can be too small or too big to aspire for such benefits of attaining high levels of maturity and capability.

If you want to look beyond Maturity Level ratings, then you’ve come to the right place. We focus on introducing CMMI principles and blending them into your organisation’s culture to achieve a truly superior and sustainable business advantage. Compliance will then be an inevitable offshoot of the actions you make.

Likewise, if you simply want to obtain a deeper understanding of CMMI and learn how it can be applied either to your entire organisation or to specific projects, we’d be happy to assist you in that regard as well.

Finally, when you’re ready, we can also conduct CMMI appraisals either for benchmarking purposes or simply for determining how well your process improvement initiatives are going.

CMMI Consulting

Are you worried that implementing CMMI might entail an overhaul of your current processes? Don’t be.

CMMI is all about improving current processes, not replacing them. Ideally, the final result of all process improvement activities should be hinged on your own business objectives and context, so we’ll make sure it remains that way when we work with you.

We rely on our extensive knowledge and experience in CMMI, engineering, software development, and technologies as well as in change and project management in providing model-based process improvement services. Whether you’re gearing up for an appraisal or simply want to employ CMMI-based practices, these are the things we can do for you.

  • Help you interpret how CMMI can be implemented in relation to your business.
  • Assist in convincing sponsors and stakeholders to support your CMMI implementation initiatives.
  • Introduce the necessary training to all individuals who need to undertake them.
  • Conduct a Gap Analysis to find out where your company’s current processes stand relative to their CMMI specifications.
  • Assemble a process group that will champion your process improvement initiatives. We’ll facilitate effective collaboration among its team members, transforming them into a cohesive force designed to carry out plans and motivate everyone else down the line.
  • Introduce tools and practices that will improve the efficiency of our process improvement initiatives.
  • Carry out periodic evaluations and produce reports to provide sponsors and stakeholders a clear picture of our progress.

CMMI Training

Still not convinced CMMI is right for you? There’s only one way to fully grasp the benefits of implementing CMMI – take the Introduction to CMMI course. Although what happens next is entirely up to you, we’re pretty sure you’ll make the right decision after passing it.

Do you need to include people from your organisation in a SCAMPI (Standard CMMI Appraisal Method for Process Improvement) team? They’ll have to undergo this course too. The Introduction to CMMI is for systems and software engineering managers and practitioners, appraisal team members, process group members, and basically anyone who want to grasp CMMI fundamentals.

This is what you’ll be able to do after going through 3 days of lectures and exercises:

  • Gain a deeper understanding of the various components of CMMI-DEV models and their relationships.
  • Discuss the process areas in CMMI-DEV models.
  • Extract and interpret aspects in the model relevant to your own organisation’s processes.

We also offer highly specialised training and workshops such as those for:

  • Achieving High Maturity Levels
  • Top Executives
  • Team Building in Preparation for Appraisals

CMMI Appraisal

An organisation new to CMMI will want to know first how far their current processes are relative to the implementation of model-based improvements in order to determine the resources and time that have to be spent to get there.

Similarly, an organisation already well acquainted with CMMI and has begun taking steps in improving processes, will eventually want to know how close it has come to the Maturity Level it has aimed for.

In both cases, these organisations will have to be assessed by a qualified CMMI appraiser to obtain an accurate picture of their current status. We can perform appraisals on either your entire organisation or on specific projects/practices within a process area. Our appraisers can conduct the following SCAMPI (Standard CMMI Appraisal Method for Process Improvement) appraisals:

  • SCAMPI Class A – This is what you’ll need if you’re aiming for a level rating.
  • SCAMPI Class B – You may want to use this for process reviews or for preparing for a SCAMPI Class A.
  • SCAMPI Class C or Gap Analysis – We typically conduct this for organisations who have yet to implement CMMI-based initiatives so that they can design the most cost-effective road map for the implementation proper.
