Scrum is a Design Framework, meaning that its approach is Empirical. It’s not like a Process that must be strictly followed. Scrum is to be seen as principles that tend to promote the concept of agility based on the Agile Manifesto.
The Agile Manifesto was originally aimed for software development but it’s principles can actually be used for any kind of development.
Nowadays Scrum is used for Software development as well as for Hardware development and seen as one of the best Framework to reach customer satisfaction, as well as meeting deadline.
Six Sigma DFSS / DMAIC
There are two kind of “Six Sigma“; one (1) for Designing new products or processes and the second (2) for Improving existing products or processs.
(1) The first one called DFSS (Design For Six Sigma) can be split in two parts;
– One is about discovering and qualifying the VOC (Voice Of the Customer),
– One is about designing the solution and making it robust against variation.
(2) The second one (called DMAIC from its roadmap) is typically faster and easier because the product or process to be improved already exists. Thus:
– The VOC is simply about verifying it’s well qualified
– The second part is about improving based on what can be done considering the age of the equipment and its return on investment.
Triz is systematic creativity process; meaning that it follows some steps that go from clarifying the problem to finding the invulnerable solution called Ideal Final Result or IFR.
Since its creation in 1946 it has grown and now includes other creativity methods for Diverge Thinking such as Osborn, De Bono, Herrmann, Reverse thinking … and for Converge Thinking such as Choice of Sparks, Lighting, Affinity Diagram, Pugh … and it’s now internationally recognized as the most powerful innovation process.
Innovation means the creation of something new and includes development of new products such as hardware or software but also production processes, measuring methods, new management practices, etc.
Lean aims to improve Processes and it’s a term that has been coined after the Toyota Production System and means slender or slim.
It’s a figure of speech to contrast efficient enterprises from those ‘fat’ from poorly managed stocks. Stocks are to be seen as indicators of bad Process efficiency.
The Lean effort is to reduce stock levels to the bare minimum using the Just-In-Time management working practice.
The Lean principles are: (1) Identify value (called VOC in Six Sigma) (2) Map the flow of this Value (3) Identify and remove constraints (4) Empower Employees (5) Continuously Improve.
