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.

When a Toyota industrial engineer named Taiichi Ohno was investigating ways to optimise production material stocks in 1953, it struck him that supermarkets already had the key. Their customers purchased food and groceries on a just-in-time basis, because they trusted continuity of supply. This enabled stores to predict demand, and ensure their suppliers kept the shelves full.
The Kanban system that Taiichi Ohno implemented included a labelling system. His Kanban tickets recorded details of the factory order, the delivery destination, and the process intended for the materials. Since then, Ohno?s system has helped in many other applications, especially where customer demand may be unpredictable.
Optimising Workflow in Call Centres Optimising workflow in call centres involves aiming to have an agent pick up an incoming call within a few rings and deal with it effectively. Were this to be the case we would truly have a just-in-time business, in which operators arrived and left their stations according to customer demand. For this to be possible, we would need to standardise performance across the call centre team. Moving optimistically in that direction we would should do these three things:
Make our call centre operation nimble
Reduce the average time to handle calls
Decide an average time to answer callers
When we have done that, we are in a position to apply these norms to fluctuating call frequencies, and introduce ?kanbanned? call centre operators.
Making Call Centre Operations Nimble The best place to start is to ask the operators and support staff what they think. Back in the 1960?s Robert Townsend of Avis Cars famously said, ?ask the people ? they know where the wheels are squeaking? and that is as true as ever.
Begin by asking technical support about downtime frequencies, duration, and causes. Given the cost of labour and frustrated callers, we should have the fastest and most reliable telecoms and computer equipment we can find.
Then invest in training and retraining operators, and making sure the pop-up screens are valuable, valid, and useful. They cannot do their job without this information, and it must be at least as tech-savvy as their average callers are.
Finally, spruce up the call centre with more than a lick of paint to awaken a sense of enthusiasm and pride. Find time for occasional team builds and fun during breaks. Tele-operators have a difficult job. Make theirs fun!
Reducing Average Time to Handle Calls Average length of contact is probably our most important metric. We should beware of shortening this at the cost of quality of interaction. To calculate it, use this formula:
Total Work Time + Total Hold Time + Total Post Call Time
Divided By
Total Calls Handled in that Period
Share recordings of great calls that highlight how your best operators work. Encourage role-play during training sessions so people learn by doing. Publish your average call-handling time statistics. Encourage individual operators to track how they are doing against these numbers. Make sure your customer information is up to date. While they must confirm core data, limit this so your operators can get down to their job sooner.
Decide a Target Time to Answer Calls You should know what is possible in a matter of a few weeks. Do not attempt to go too tight on this one. It is better to build in say 10% slack that you can always trim in future. Once you have decided this, you can implement your Kanban system.
Introducing Kanban in Your Call Centre Operation Monitor your rate of incoming calls through your contact centre, and adjust your operator-demand metric on an ongoing basis. Use this to calculate your over / under demand factor. Every operator should know the value on this Kanban ticket. It will tell them whether to speed up a little, or slow down a bit so they deliver the effort the call rate demands. It will also advise the supervisor when to call up reserves.
Total Quality Management (TQM) is another business management approach that focuses on the involvement of all members of the organisation to participate in improving processes, products, services, and the culture in which they work in. It is important that every team member realises how each individual and each activity affects, and in turn is affected by, others.
With the use of combined quality and management tools, TQM also aims to reduce losses brought about by wasteful practices, a common concern in most companies. Using the TQM strategy, business would also be able to identify the cause of a defect, thereby preventing it from entering the final product.
Deming’s 14 Points
At the core of the Total Quality Management concept and implementation is Deming’s 14 points, a set of guidelines on quality as conceptualised by W Edwards Deming, one of the pioneers of quality. Deming’s 14 points are as follows:
Create constancy of purpose for improving products and services.
Adopt the new philosophy.
Cease dependence on inspection to achieve quality.
End the practice of awarding business on price alone; instead, minimise total cost by working with a single supplier.
Improve constantly and forever every process for planning, production and service.
Institute training on the job.
Adopt and institute leadership.
Drive out fear.
Break down barriers between staff areas.
Eliminate slogans, exhortations and targets for the workforce.
Eliminate numerical quotas for the workforce and numerical goals for management.
Remove barriers that rob people of pride of workmanship, and eliminate the annual rating or merit system.
Institute a vigorous program of education and self-improvement for everyone.
Put everybody in the company to work accomplishing the transformation.
But if you were to reduce to bare bones the TQM philosophy from Deming’s 14 points, it would all come down to two simple goals:
To make things right the first time; and
To work for continuous improvement.
As with all other quality management process, the end goal is to be able to offer products and services that meet and even exceed customer’s expectations.

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.
