Analyzing our Value Stream we identify a number of constraints that limit its effective capacity. The most visible constraints are the capacity of the different steps. But there are other, not so obvious, constraints such as the capacity variation of some steps. Process variation has been described as a virus infecting the value stream: it causes chaos and it is often undetected.     Dice Throwing Exercise A bottleneck limits the effective capacity of the whole line. Bottlenecks caused by variation are more subtle and difficult to detect and act upon. Process simulation can help us experience the effects of different types of constraints, try solutions and detect possible side effects. Process simulation helps us understand the value stream dynamic behavior: how variation affects key process metrics such as WIP, Lead time, Throughput, Cycle time, On Time Delivery, etc. Understanding these dynamic effects will enable us to get to the root cause of problems implementing def...

Course objectives: Understand the importance of process orientation Apply Six Sigma DMAIC (Define, Measure, Analyse, Improve, Control) methodology Experience the negative effects of variation, see ways to measure and reduce it Find out different types of process factors: dependent, independent, controllable or not Ask the right questions to get to the root cause of problems Identify potential problems before they actually take place Apply this methodology and tools to one's own process with an improvement project IASSC Green Belt Lean Six Sigma Body of Knowledge 1. Define What is important? What is the problem? Project Scheduling Project charter: Goals, objectives, scope, justification, project participants Current status: go to Gemba Problem definition: SMART The voice of the customer: translate it to process specs Process map and flow chart: SIPOC Process Value Stream Map with MS Excel. 2. Measure What to measure?: Voice of the customer, Voice of the process, Business results P...

  The COVID pandemia we have suffered worldwide has changed many ways of doing things both at work and in the home. A common practice of sharing reporting terminals in the manufacturing lines has become an unacceptable risk. One alternative to solve this problem is to bring  your own device (BYOD) to do the reporting. BYOD is making significant inroads in the business world, with about 75% of employees in high-growth markets such as Brazil and Russia and 44% in developed markets already using their own technology at work. One major advantage of using your own phone is that the skill is already there: a new IT device would require training.   Some Possible Business Uses for an Employee's Own Smartphone Workplace data collection in real time Incident reporting anywhere any time Repair action reporting from anywhere when it is complete Value Stream Map building and validation in Gemba (where the action is) Real-time Statistical Process Control Real time project or manufac...
