In some situations, Six Sigma practitioners find a Y that is discrete and Xs that are continuous. How can a regression equation be developed in these cases? Black Belt training indicated that the correct technique is something called logistic regression or binary regression. But this tool is often not well understood.…
The two-sample t-test is one of the most commonly used hypothesis tests in Data Analytics or Lean Six Sigma work. The two-sample t-test offers the statistics for comparing average of two groups and identify whether the groups are really significantly different or if the difference is due instead to random chance.…
Measurement error is unavoidable. There will always be some measurement variation that is due to the measurement system itself.
Most problematic measurement system issues come from measuring attribute data in terms that rely on human judgment such as good/bad, pass/fail, etc. This is because it is very difficult for all testers to apply the same operational definition of what is “good” and what is “bad.”…
Not continuous improvement nor innovation have to start with massive initiatives. To the contrary, it needs to be part of the DNA of an organisation if you want to ensure that your aforementioned initiative is successful and lasting. …
Our business simulation is intended to show the business impact of improving and even redesigning a rather simple business process – the effect of Business Process Re-engineering (BPR). Basic yet powerful tools come to play. Process KPIs as well as customer satisfaction and customer KPIs are a gauge for the degree of improvement. We have been running this simulation nearly a hundred times with teams from different industries.…
When Uwe asked me whether I would like to go to Gemba in order to help understand the client’s process we have been studying, I looked it up on Google. To my surprise, Gemba is not a secluded, unknown part of Singapore. Gemba (现场) is a Japanese word that means “the real place”. Japanese detectives use Gemba to point to the crime scene.
In a coaching or mentoring relationship, finding the right moment for performing the coaching is critical. Often, coaching attempts go wrong because the moment is just not right. But, how do you know whether it is a good time for coaching? Just ask yourself whether you have the right essentials for coaching someone.…
Some twenty years ago, just after I was hired by General Electric Capital and tasked to implement something as strange to a bank as continuous improvement in their newly acquired, yet dusty German banking environment, life was not walk in the park anymore. Gaining the skills for the new job with the help of the outstanding GE Capital people development engine was challenging but rewarding. But I never learned about Management by Walking About (MBWA).
When I joined General Electric Capital many years ago, I asked them why they would hire an engineer with no prior banking knowledge. The answer was quite a pleasant surprise: “We have enough people who understand banking. Unfortunately, we do not have those with a process mind-set.”
Now I know, banking is a productivity gold mine.…
Waiting for the next “great innovative product idea” may never get you one step closer to a higher level of customer satisfaction, more revenue and consistent business growth. Instilling an innovative mind-set facilitated by some simple creativity tools that are supported by empowerment does. Innovate – every day.…
Strategic workforce planning is the process of matching workforce demand and supply over a foreseeable time period. Organisations conduct workforce planning that builds upon quantitative activities such as headcount planning and workforce analytics, and use these data as part of qualitative decisions to support and implement organisational strategies.
“Bob is not doing his job. Always mistakes. What should I do with him?”
“Mary has messed up our relationship with a key client. I had to step in to save the day.”
Having done a multitude of projects in all kinds of private and public organisations, we have frequently encountered these and other remarks by managers about their staff.
Recently, I had coffee with Edward, an old friend – or better: one of my mentors. He is approaching seventy and yet is in the pink of health. So I asked whether he plays golf 24/7. His response came a bit as a surprise.…
Whenever I entered the management team meeting at MyBank, I had my state-of-the-art PowerPoint pitch showing the performance of each department and its core processes as part of our dashboard. Every month, we got the latest underlying data together, aggregated them and displayed an overall dashboard of how the business was doing. With that, we had a clear Line-of-Sight.…
Given today’s need for HR professionals to be Strategic Business Partners, to be a ‘Voice of Conscience’ to the CEOs as well as Champion for the Employees, those with background in proven management methodologies and tools such as Lean, Six Sigma or Kaizen have a great advantage. …
