Six Sigma has received much attention worldwide as a management strategy that is said to have brought about huge improvements and financial gains for such big-name companies as Allied Signal, General Electric (GE) and Motorola.
If you want to give your business the chance to attain the same resounding success, Six Sigma could be the method that will steer you towards that direction.
What is Six Sigma?
So what really is it? Six Sigma is a business management tool that was developed using the most effective quality improvement techniques from the last six decades. Basing its approach on discipline, verifiable data, and statistical calculations, Six Sigma aims to identify the causes of defects and eliminate them, thereby resulting in near-perfect products that meet or exceed customer’s satisfaction.
The core concept behind the Six Sigma method is that if an organisation can quantify the number of “defects” there are in a particular process, improvement activities can be implemented to eliminate them, and get as close to a “zero defects” scenario as possible. Defect here is defined as any process output that fails to meet customer specifications.
Six Sigma is also unique from other programs in that it calls for the creation of a special infrastructure of people within the organisation (“Champions“, “Black Belts“, “Green Belts“) who are to be expert in the methods.
Six Sigma Methodologies
When implementing Six Sigma projects, two methodologies are often employed. Although each method uses five phases each, these two are distinguished from each other using 5-letter acronyms and their specific uses.
DMAIC ? is the project methodology used to improve processes and maximise productivity of current business practices. The 5 letters stand for:
D ? Define (the problem)
M ? Measure (the main factors of the existing process)
A ??Analyse?(the information gathered to deter mine the causes of defects)
I ? Improve (the current process based on the analysis)
C ? Control (all succeeding processes so as to minimise additional defects)
DMADV – is the method most suitable if your business is looking to create new products or designs. The acronym stands for:
D ? Define (product goals as the consumer market demands)
M ? Measure (and identify product capabilities and risks)
A ??Analyse?(to create the best possible design)
D ? Design (the product or process details)
V ? Verify (the design)
How does Six Sigma differ from other quality programs?
If you think that Six Sigma is just another one of those business strategies that produce more hype than actual results, think again. Six Sigma uses three key concepts that sets it apart from other business management methods.
It is strictly a data-driven approach, where assumptions and guesswork do not figure in the decision making.
It focuses on achieving quantifiable financial results ? the bottom line ($) ? as much as giving emphasis on customer satisfaction.
It requires strong management leadership, while at the same time creating a role for every individual in the organisation.
Is Six Sigma right for your business?
While many other organisations such as Sony, Nokia, American Express, Xerox, Boeing, Kodak, Sun Micro-systems and many other blue chip companies have followed suit in adopting Six Sigma, the truth is, any company — whether you have a large manufacturing corporation, or a small business specialising in customer service.
Certainly, there is a lot more to Six Sigma than what you can probably absorb in one sitting or reading.

DevOps ? a clipped compound of development and operations – is a way of working whereby software developers are in a team with project beneficiaries. A client centred approach extends the project plan to include the life cycle of the product or service, for which the software is developed.
We can then no longer speak of a software project for say Joe?s Accounting App. The software has no intrinsic value of its own. It follows that the software engineers are building an accounting app product. This is a small, crucially important distinction, because they are no longer in a silo with different business interests.
To take the analogy further, the developers are no longer contractors possibly trying to stretch out the process. They are members of Joe?s accounting company, and they are just as keen to get to market fast as Joe is to start earning income. DevOps uses this synergy to achieve the overarching business goal.
A Brief Introduction to OpsDev
You can skip this section if you already read this article. If not then you need to know that DevOps is a culture, not a working method. The three ?members? are the software developers, the beneficiaries, and a quality control mechanism. The developers break their task into smaller chunks instead of releasing the code to quality control as a single batch. As a result, the review process happens contiguously along these simplified lines.

Working quickly and releasing smaller amounts of code means the OpsDev team learns quickly from mistakes, and should come to product release ahead of any competitor using the older, more linear method. The shared method of working releases huge resources in terms of user experience and in-line QC practices. Instead of being in a silo working on its own, development finds it has a richer brief and more support from being ?on the same side of the organisation?.
The Key Role that Application Program Interfaces Play
Application Program Interfaces, or API?s for short, are building blocks for software applications. Using proprietary software-bridges speeds this process up. A good example would be the PayPal applications that we find on so many websites today. API?s are not just for commercial sites, and they can reduce costs and improve efficiency considerably.
The following diagram courtesy of TIBCO illustrates how second-party applications integrate with PayPal architecture via an API fa?ade.

The DevOps Revolution Continues ?
We close with some important insights from an interview with Jim Stoneham. He was general manager of the Yahoo Communities business unit, at the time Flickr became a part. ?Flickr was a codebase,? Jim recalls, ?that evolved to operate at high scale over 7 years – and continuing to scale while adding and refining features was no small challenge. During this transition, it was a huge advantage that there was such an integrated dev and ops team?
The ?maturity model? as engineers refer to DevOps status currently, enables developers to learn faster, and deploy upgrades ahead of their competitors. This means the client reaches and exceeds break-even sooner. DevOps lubricates the value chain so companies add value to a product faster. One reason it worked so well with Flickr, was the immense trust between Dev and Ops, and that is a lesson we should learn.
?We transformed from a team of employees to a team of owners. When you move at that speed, and are looking at the numbers and the results daily, your investment level radically changes. This just can’t happen in teams that release quarterly, and it’s difficult even with monthly cycles.? (Jim Stoneham)
When past actions in software development return to haunt you…
Is your business being bogged down by technical debt? Let’s look at measures that you can take to reduce it and scale your operations without the weight pulling you back.
Work with a flexible architecture.
Right from the word go, you want to use architecture whose design is malleable, especially with the rapid rate of software evolution witnessed today. Going with an architecture that keeps calling for too much refactoring, or whose design won’t accommodate future changes will leave you with costly technical debt. Use scalable architecture that allows you to modify or add new features in future releases. While on this, complex features required in the final product should be discussed at the planning stage, that way simplified solutions that will be easier to implement can be identified, as this will lead to less technical debt in the long run.
The Deal with Refactoring
This is basically cleaning up the code structure without changing its behaviour. With the updates, patches, and new functionalities that are added to the systems and applications, each change comes with the threat of more technical debt. Additionally, organisations are increasingly moving their IT infrastructure from on-premises facilities to colocation data centres and deploying them on the cloud. In such scenarios, some workarounds are often needed to enable the systems to function in the new environments, which they hadn’t been initially developed to accommodate. Here, you will need to take some time to refactor the existing system regularly, streamlining the code and optimizing its performance – and this will be key to pay down the tech debt. When working with a flexible architecture from the start, the amount of work that goes into this will be reduced, meaning there’ll be less tech debt involved.
Run discovery tests
Discovery testing essentially takes place even before a line of code is written for the system or application. This takes place at the product definition stage, where human insight software is used to understand the needs of the customer and is particularly helpful in setting priorities for the development work that will be carried out. It gives your business the opportunity to minimize the technical debt by allowing customers to give you a roadmap of the most pertinent features desired from the product.
Routine code review
Getting a fresh look at the product or application from different sets of eyes in the development team will improve the quality of the code, thus reducing technical debt. There’s a catch though – this should be planned in a convenient way that doesn’t end up becoming a burden for the developers. Here are suggestions:
● Break down pull requests
Instead of having complex pull requests where numerous changes in the code are introduced at a go, have this broken down into smaller manageable pull requests, each with a brief title and description about it. This will be easier for the code reviewer to analyse.
● Define preferred coding practices
Documenting the preferred coding style will result in cleaner code, meaning the developers will focus their effort on reviewing the code itself, not losing time on code format debates.
Test automation
Relying only on scheduled manual testing opens you up to the risk of technical debt accruing rapidly, and not having sufficient resources to deal with the accumulated problems when they are identified. Automated testing on the other hand enables issues to be uncovered quicker, and with more precision. For instance, you can have automated unit tests that look at the functioning of the individual components of a system, or regression testing where the focus is on whether the code changes that have been implemented have affected related components of the system. However, establishing and maintaining automated testing will require quite some effort – making it more feasible for the long-term projects.
Keep a repository that tracks changes made
Do you have a record of changes made in the software? Keeping one in a repository that is accessible by the development team will make it easy to pin-point problems at their source. For instance, when software is being migrated to a new environment, or legacy software is in the process of being modernised, you will want to have an accurate record of changes that are being introduced, that way if there is an undesired impact on the system this it will be easier to zero-down on the cause.
Bring non-technical stakeholders on board
Does this conversation sound familiar?
Development Team: “We need to refactor the messy code quickly”
Product Team: “We have no idea what you are saying”
On one hand, you have the management or product team defining the product requirements, creating a project roadmap, and setting its milestones. On the other hand, there’s the software development/engineering that’s primarily focused on the product functionality, technical operations and clearing the backlog in code fixes. Poor communication between the two teams is actually a leading cause of technical debt.
For you to take concrete steps in managing your technical debt, the decision-makers in the organisation should understand its significance, and the necessity of reducing it. Explain to them how the debt occurred and why steps need to be taken to pay it down – but you can’t just bombard them with tech phrases and expect them to follow your thought process.
So how do you go about it? Reframe the issues involved with the technical debt and explain the business value or impact of the code changes. Basically, the development team should approach it from a business point of view, and educate the management or production team about the cost of the technical debt. This can include aspects such as expenses in changing the code, salaries for the software engineers especially when the development team will need to be increased due to the workload piling up, as well as the revenue that is lost when the technical debt is allowed to spiral.
The goal here is to show the management or production team how issues like failing to properly define the product requirements will slow down future software development, or how rushing the code will affect the next releases. That way, there will be better collaboration between the teams involved in the project.
Allocate time and resources specifically for reducing technical debt
With management understanding that working with low-quality code is just like incurring financial debt and it will slow down product development, insist on setting time to deal with the debt.
For instance, when it comes to the timing of application releases, meetings can be conducted to review short- and longer-term priorities. These meetings – where the development team and product team or management are brought together, the developers point out the software issues that should be resolved as a priority as they may create more technical debt. Management then ensures that budgets and plans are put in place to explicitly deal with those ongoing maintenance costs.
Retire old platforms
While most of the resources are going into developing new applications and improving the systems being used, the organisation should also focus on retiring the old applications, libraries, platforms, and the code modules. It’s recommended that you factor this into the application release plans, complete with the dates, processes and costs for the systems involved.
Total overhaul
When the cost and effort of dealing with the technical debt far outweighs the benefits, then you may have to replace the entire system. At this tipping point, you’re not getting value from the technical debt, and it has become a painful issue that’s causing your organisation lots of difficulties. For instance, you may be dealing with legacy software where fixing it to support future developments has simply become too complicated. The patches available may only resolve specific issues with the system, and still leave you with lots of technical debt. Here, the best way out is to replace the system in its entirety.
Final thoughts
Every software company has some level of tech debt. Just like financial debt, it is useful when properly managed, and a problem when ignored or allowed to spiral out of control. It’s a tradeoff between design/development actions and business goals. By taking measures to pay down your organization’s debt and address its interest as it accrues, you will avoid situations where short term solutions undermine your long-term goals. This is also key to enable your business to transition to using complex IT solutions easier, and even make the migration between data centres much smoother. These 8 measures will enable you to manage your technical debt better to prevent it from being the bottleneck that stifles your growth.
A mobile workforce management software is key to managing an efficient field workforce.? Managing a staff of people can be tricky in any industry. Try keeping track of employees on shifting jobsites, many whom are paid hourly or temporary workers. The added pressure of ensuring the right workers get to the right sites at the right times, but they also need to track hours, parts used, vehicles and equipment assets.
In a previous post, we defined what is an operational review and why they play a key process in the continual evolution of successful businesses.?
Operational reviews allow the organization members to evaluate their performance, according to the procedures, resources properly, timescales and budgets.
In this post, we’ll take a closer look at how to implement an operational review and the steps typically undertaken to help you and your organisation to implement an operational review.
What the steps in a Operational Review Process
There are typically six steps in an operational review that range from preparatory work conducting interviews and collecting documents to the presentation of the final written report.
An audit should be customized to meet a organisatons specific needs, so standard steps can and should only serve as a guideline.? Management and internal and external auditors should adjust the process to address the company’s particular goals and objectives.
Initial Management Meeting
Understanding the problem is the first crucial step of an operational review. This is one of major areas of discussions when the audit team meets with the management, and department heads will be asked to identify any specific areas of concern. Once the problem is identified, it would be easier to come up with workable solutions.
Conduct Interviews
The next step in the evaluation is carried out with experienced teams doing interviews and keeping close observation. Each team essentially watches how employees carry out their responsibilities. This is considered a key part of the process.
When doing the interview, it is also vital that the observing team gains the employees? trust and confidence. Likewise, the staff must be assured that whatever transpires between the team and the employee will be kept confidential. Management must therefore guarantee anonymity to anyone who offers critical information, lest employees withhold vital information and render the data gathered inaccurate.
Systems Review
Employees and management practices will be reviewed by the assessing team according to the standard policies and guidelines of the company. The effectiveness of the controls in place as well as their appropriateness to the current operating conditions will also be evaluated.
Reporting
A documentation of the data gathered and the assessment of the evaluating team, will be submitted to the management after the review process. Flow charts and written narratives of departmental activities are usually part of this report. This is also where observations and recommendations of the team will be presented to the department heads concerned.
Review Results
While the operational review is being conducted, it is important to take into account the vital factors that affect the company: the people, processes, procedures, and strategies. These four factors can determine the company?s progress in the future.
Key Areas of focus in operation reviews
At a minimum an operational review should include the following key ares of assessment
Management Control
Responsibilities, authority, and the scope in which an employee has the freedom to act must be clearly defined and documented. A complete and specific job description for instance, would give the employee a clear perspective on how he acts and functions within the company.
Boundaries should be set not only to benefit the employer but more so the employee as well.
Moral and Ethical Guidelines
Moral and ethical guidelines are just as important to ensure for a smoother employer?employee relationship. Otherwise, personal issues such as work ethics, work attitude and personal values may post problems in the long run if such guidelines are not drawn properly before relationships are established.
Processes and procedures
Evaluating processes is only beneficial if the company itself updates its processes and procedural manuals regularly, or at least when needed. Such protocols may need revision and some steps may be obsolete already. Improving a company?s processes and procedures doesn’t always entail cost. In fact, improvised procedures may even be cost-effective and could make the processes more manageable.
Communication and reporting standards
Gaps in communication could result in serious lapses in internal controls, putting the company and/or its assets at risk. This is where the importance of timely and clear communication comes in. Likewise, reports must be useful, and the flow of information and how it is processed must keep pace with the company?s growth.
Information technology (IT) and security controls can also be included under the communication clause. Proper IT security policies must be in place, state-of-the-art protection techniques employed, and everything be documented, periodically updated, and continually monitored.
Strategic planning and tactics
No company can ever be complete without its strategies. It would unwise for any organization to proceed without first knowing where it stands and what direction it wants to take. Strategic planning draws such a map. It must be aligned to the mission and vision of the company, and should also coincide with the organizational goals set. Strategic planning deals with these three key questions:
What do we do now
Whom do we do it for?
How can we overcome competition
Without clear strategic direction, expectations would likely differ between ownership and management.
Contingency planning, testing and recovery
Contingency plans must be up-to-date, and are essential to the organization. If one course of action fails, the company should have plan B, C and so on. In addition, an organization should be prepared to respond to interference’s.
This includes establishing a formal process to review transactions processing during both disruption and recovery.
Presentation of Report
Based on your objectives and our findings, we will develop detailed recommendations to improve your company?s performance and productivity. Our written report will include a list of both short-term and long-term projected improvements and courses of action, to be mutually agreed upon by both parties.
To ensure the achievement of the improvements we outlined, our team will also assist in the implementation of these modifications.
The plan has three levels of recommendations: one for executives, another for management, and a third one for staff.
The executive summary concentrates on your company?s strengths, weaknesses, opportunities and threats to its entirety. It includes recommendations for any needed changes in policy or governance.
The management plan is based on employee feedback and includes areas of immediate improvement as well as identification of potential problem areas. Concerns from the bottom level management can now be forwarded to the top level management in formal writing. Better working relationships may evolve from this, thereby setting the work environment for a higher productivity ratio.
Lastly, the staff report deals with topics like charting the hierarchy of the organization, and discussing in detail specific control objectives that are critical to the company?s mission. Part of our goal is to encourage personnel to pay close attentions to such changes, if any, as these efforts are essential if they want to bring about both organizational and personal success.
