Six Sigma

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.

Why Executives Fail & How to Avoid It

The ?Peter Principle? concerning why managers fail derives from a broader theory that anything that works under progressively more demanding circumstances will eventually reach its breaking point and fail. The Spanish philosopher Jos? Ortega y Gasset, who was decidedly anti-establishment added, “All public employees should be demoted to their immediately lower level, as they have been promoted until turning incompetent”.

The Peter Principle is an observation, not a panacea for avoiding it. In his book The Peter Principle Laurence J. Peter observes, “In a hierarchy every employee tends to rise to his level of incompetence … in time every post tends to be occupied by an employee who is incompetent to carry out its duties … Work is accomplished by those employees who have not yet reached their level of incompetence.”

Let’s find out what the drivers are behind a phenomenon that may be costing the economy grievously, what the warning signs are and how to try to avoid getting into the mess in the first place.

Drivers Supporting the Peter Principle

As early as 2009 Eva Rykrsmith made a valuable contribution in her blog 10 Reasons for Executive Failure when she observed that ?derailed executives? often find themselves facing similar problems following promotion to the next level:

The Two Precursors

  • They fail to establish effective relationships with their new peer group. This could be because the new member, the existing group, or both, are unable to adapt to the new arrangement.
  • They fail to build, and lead their own team. This could again be because they or their subordinates are unable to adapt to the new situation. There may be people in the team who thought the promotion was theirs.

The Two Outcomes

  • They are unable to adapt to the transition. They find themselves isolated from support groups that would otherwise have sustained them in their new role. Stress may cause errors of judgement and ineffective collaboration.
  • They fail to meet business objectives,?but blame their mediocre performance on critical touch points in the organization. They are unable to face reality. Either they resign, or they face constructive dismissal.

The Warning Signs of Failure

Eva Rykrsmith suggests a number of indicators that an individual is not coping with their demanding new role. Early signs may include:

  • Lagging energy and enthusiasm as if something deflated their ego
  • No clear vision to give to subordinates, a hands-off management style
  • Poor decision-making due to isolation from their teams? ideas and knowledge
  • A state akin to depression and acceptance of own mediocre performance

How to Avoid a ?Peter? in Your Organization

  • Use succession planning to identify and nurture people to fill key leadership roles in the future. Allocate them challenging projects, put them in think tanks with senior employees, find mentors for them, and provide management training early on. When their own manager is away, appoint them in an acting role. Ask for feedback from all concerned. If this is not positive, perhaps you are looking at an exceptional specialist, and not a manager, after all.
  • Consider the future, and not the past when interviewing for a senior management position. Ask about their vision for their part of the organization. How would they go about achieving it? What would the roles be of their subordinates in this? Ask yourself one very simple question; do they look like an executive, or are you thinking of rewarding loyalty.
  • How to Avoid Becoming a ?Peter??Perhaps you are considering an offer of promotion, or applying for an executive job. Becoming a ?Peter? at a senior level is an uncomfortable experience. It has cost the careers of many senior executives dearly. We all have our level of competence where we enjoy performing well. It would be pity to let blind ambition rob us of this, without asking thoughtful questions first. Executives fail when they over-reach themselves, it is not a matter of bad luck.

How DevOps oils the Value Chain

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.

This is a marked improvement over the previously cumbersome method below.

Write the Code ? Test the Code ? Use the Code
? Evaluate, Schedule for Next Review ?

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)

Renewable energy – Is it a common man’s cup of tea?
I came across an article on a young graduate in renewable energy engineering. The fellow was doing technical sales and marketing jobs for renewable energy products though he felt that as a graduate, he ought to be doing more than just sales. His, sentiments, I can relate with but again thinking about the field of renewable energy, how many people understand what it is, its importance/ benefits, how to acquire it, its installation, costs etc.? Renewable energy is energy generated from natural resources. The renewable energy sources include sunlight, wind, rain, tides, geothermal heat and various forms of biomass. These sources are renewable naturally and continuously replenished, therefore this energy cannot be exhausted. Renewable energy technologies range from solar power, wind power, hydroelectricity/micro hydro, biomass and bio-fuels for transportation. Back to the aspiring young professional who felt that his place in the renewable energy sector lies in doing strategies and coming up with new products-the advice fronted to him was that doing technical sales is the best job for engineers, as it helps them impact on users of their products. Sales entail interacting with customers and knowing their needs so that the product features can be enhanced to suit the customer?s needs. Now, that is brilliant and accurate advice. It is however important to take into consideration that renewable energy is not a common man?s cup of tea and right now the focus all over the world is to build green economies. To me the need for more and more people to understand the benefits, savings and cost of renewable energy cannot be overemphasised. Effort should be made to keep marketing of renewable energy products/ services simple and conversational by avoiding use of acronyms or jargon explaining about operational details. More impact can be made if a marketing rather than technical sales approach is used. Technical sales have been described as boring (can be used as a sleeping aid), tends to use extensive vocabulary, jargon and acronyms that product users cannot relate with and tends to discuss the products technical aspects as opposed to the benefits to the customer. Fun should be created out of all this by making things simple and demonstrating cost savings and benefits of renewable energy.
