RPA is expected to grow faster with AI getting stronger. Image Analysis and Text Analysis, for example are two areas within RPA that will be more successful as it is infused with Machine Learning capabilities. Reliable Artificial Intelligence can make more processes RPA-ready in future. Large number of processes today are considered unsuitable for RPA because of good percentage of exceptions in them. If Artificial Intelligence can reduce these exceptions significantly, or ideally eliminate them, RPA will become the preferred mechanism for such processes.

Hi Ronaq, this can vary depending on whether Six Sigma is growing or diminishing within the company.

Bench highlights that Customer Satisfaction is linked with Employee Satisfaction, which in turn is driven by monotony at work. Monotony in turn depends on extent of standardization at the work place which increases when more Lean Six Sigma projects are done. If there are more people like Mark, there will be more Lean Six Sigma projects. He expects Mark to join the dots. Any views on this one?

I do see some companies asking for domain specific knowledge. Our experience has been largely different. Majority of the global leaders that we have worked with were our first client in that sector. This has happened in several domains - here are a few - FMCG, Shoes, Aircraft, Starch, Soft Drinks, Liquor, Web Search, e-commerce, Fintech, Navigation, and Real Estate Management Services. I have seen hundreds of professionals shifting to highly unrelated sectors, for example, Telecom to Hospitality, Manufacturing to IT, Banking to IT, ITES to Banking and so on.

Bench's company has been working hard and making small cost reductions year on year while Mark's company created a new offering that brought down the cost drastically. Mark's team used the power of DFSS. DFSS (Design for Six Sigma) is a methodology that is used for designing new products and services. This methodology is not very popular as only companies with long term thinking can make good use of it. A small number of our clients ask for DFSS and then make sure they design robust products and services to take a lead in the market place.

Description - Bench happily highlights that while planning his career, he had considered the choice between being a Generalist or a Specialist early in his life. Mark wants to know about the decision that he took. Bench says that he decided to keep options open for himself and proclaims himself as a "very general Generalist". After listening to Bench, Mark says that he has realized that he has taken a path different from the two options. He considers himself as a "specialized Generalist" or what can be considered as a "generalized Specialist". Bench want to understand what this means. Mark explains that he is a Business Excellence Master Black Belt. He calls himself a generalized Specialist as he specializes in problem solving which he can do in any sector. He further explains that he could be considered a generalist too as he can work with large variety of processes but in a specialized way. This cartoon depicts that Lean Six Sigma and Business Excellence competencies allows one to be specialized without dependence on a specific industry or functional domain.
