Hi Jeniffer, Education, Transport, Education, Software, BPO etc are included in the links above. Please review them.

Hi Venkatesh, There are a few reasons why it has not succeeded as much as it should have. Small farmlands make it hard to reduce risks. The government initiative is limited. People who own agri-fields have limited education to understand and absorb such concepts. Any Agri-University in India has not tried to scale it up. It is not as if results are not available to India. Companies like Syngenta and Monsanto have been partnering with Agriculturists to reap the benefits in a partnering fashion.

Hi Sathiyaraj, That is a good explanation!

Hi Devang, Many companies including some of the e-commerce leaders that we work with have such Supplier Management functions. We conduct a full-fledged program on Vendor Managed Operations for such functions. This program covers efficiency in four sections. The outline can be seen here - https://www.benchmarksixsigma.com/corporate-programs/vendor-managed-operations-efficiency/. There is a large scope for cutting waste in each area. Hope this helps.

Whether machines can behave like humans or not has been an intriguing question for a long time. Why do we want to know this? The quest can be divided into into two parts - 1. Can machines behave as rationally as humans can? Since IBM’s Deep Blue had beaten Kasparov in a game of chess, more powerful computers have come in. The latest chess software called Komodo has an Elo rating as high as 3304 which is 450 above any human. Such evaluation and mastery is certainly of interest to the excellence community. 2. Can machines imitate humans and be similar even in irrational behaviours? This question is of interest to security experts who want to know if certain actions are being taken by computer (viruses, for example) instead of humans. Many times computers fail to behave irrationally and give away their presence due to patterns. As an example, computer virus can bring in thousands of fictitious members into a forum or online community by creating fake email ids and even clicking on verification emails by logging in to those email addresses. Google and other online companies have been creating anti spam solutions by figuring out patterns that the computers fail to match with humans. Most of the times computers tend to be more rational than humans as they have an algorithm driving them. Only time will tell if the fight with viruses will be won by well meaning humans or not.

Some of tools that allow for customisation and enhancements in themselves are as follows - Kanban board - This provides endless opportunities for improvement in terms of breaking up of tasks, marking expedite lanes, adding tasks on kanban cards etc. Online Kanban board platforms provide even more methods of customisation and tool improvement. Future VSM - The extent and format of details that are to be captured in a future VSM have unlimited opportunities for improvement. Andon Boards - Andon boards have infinite methods of adding details in terms of who should get alerts of what kind with what kind of escalation and how will resolution feedback be re-circulated (etc) Kaizen - The way in which Kaizens are identified, planned, executed and the way feedback and efficiency is tracked provides continuous improvement opportunities. The Lean Champion needs to be on the lookout for methods and approaches that make Lean tools more effective and therein lies the opportunity of maximising the value generation for a Lean Enterprise.

Q. 142 Turing test checks if a machine can imitate intelligent and unintelligent behaviors of humans.
