Making Sense of the Wilcoxon Test

At MyInsurance, survey results have been collected in 2017, 2018 and 2019. The rating was done on a 10-point Likert ranging from 1 … very poor to 10 … outstanding. As always, the upper 3 points, i.e. 8, 9 and 10, are seen as customer is satisfied. All other ratings are undesirable. How did MyInsurance do over the years?

Demystifying Lean Six Sigma

MYTH: LEAN SIX SIGMA HAS MANY TOOLS I DO NOT NEED. Certainly, life is much easier without the need to choose between 50 advanced tools for problem solving. However, if the only tool available is a hammer, everything looks like a nail. In reality, there is a multitude of process problems that need more than a hammer…

Beware the Hawthorne

“We have great news for you. Our project is delivering results already.” The team is all smiles when they give this update during the project meeting. The carefully prepared graphs unveil a remarkably shorter time for the whole process, from customer request to delivery of results. “We have applied a hypothesis test and the result is significant with a p-value of flat zero!”

"Moment

Do You Know About Your Moment of Truth?

The Moment of Truth is the short timeframe when a customer experiences the product or service that many people have often prepared over months. It is the moment when a small, often unintentional mishap has the huge potential to spoil the result of hard work by others in the organisation behind the scenes.

Continuously Innovating Highly Effective Processes

Just some weeks ago, I filed my tax in Singapore. It took me about twelve minutes at my computer at home on a Sunday afternoon in April. It was not straight forward, I needed to make some amendments and additional inputs to what IRAS had already prepared for me. Yet, it was really easy to understand, very effortless to do and I have the strong feeling I did not make a mistake. Twelve minutes. Really.

Making Sense of Test For Equal Variances

Three teams compete in our CHL business simulation. After completing Day One, it looks like the teams show a very different performance. Although the means look very similar, the variation is strikingly different. To test this assumption of different variation among the teams, the Test for Equal Variances is deployed.

Make Use of Your Survey Data – Kano Them

Survey data should be analysed with different tools at the same time in order to find the most appropriate method to show “patterns in data” that lead to conclusions. The Kano analysis or the Jaccard index offer additional insights into survey data.
Remember: Attaining the data is expensive, analysing them is cheap.

Manager as Coach

To be a good coach is hard work. Coaching requires a set of skills that need to be built. The journey as a coach is a long but rewarding one. How will we know when we have arrived? “With the best of leaders, when the work is done, the project is completed, the people all say, ‘We did it ourselves.’” Lao Tzu

"Two

Making Sense of the Two-Proportions Test

Consider a production process that produced 10,000 widgets in January and experienced a total of 112 rejected widgets after a quality control inspection (i.e., failure rate = 1.12%). A Six Sigma project was deployed to fix this problem and by March the improvement plan was in place. In April, the process produced 8,000 widgets and experienced a total of 63 rejects (failure rate = 0.79%). Did the process indeed improve?

Working Capital Meets Lean Six Sigma

Working capital is influenced by a complex system consisting of external and internal factors as well as strategic decisions. External drivers are composed of economy, cost of capital, regulations and market position. Strategic decisions include geographies of customers and suppliers, customer mix and vertical integration. Tactical factors are policies, processes and metrics, systems and tools and also the degree of execution of the former.

"Competencies

Beyond HR Data Analytics – Competencies HR Professionals Should Possess

Given today’s need for HR professionals to be strategic business partners, to be a ‘Voice of Conscience’ to the CEO as well as champion for the employees. Those with background in proven management methodologies and tools have a great advantage. HR Professionals who can present their business case for HR strategies and interventions with a compelling return on investment, supported by rock-solid data, will be well respected and regarded.
