I have chosen this topic for today to help individuals to understand in a better way the differences and similarities between the software development methods:

• Waterfall (traditional);
• First Generation of Agile (XP, Scrum);
• and Second Generation of Agile (Lean, Kanban, BDD).

    As Agile Software Development gains more and more ground in the IT world, I thought it may be a good idea to write a few personal opinions about this topic.

    It is clear for everybody that nowadays we have an increased competitiveness in our global economy, so this is a great reason to considering to transform your businesses to Lean and Agile.

    After Lean Principles and Six Sigma Principles,  I think it might be a good idea to approach Lean Six Sigma Principles topic.

    When a company needs a Lean Six Sigma Professional, we can say that its executives are aware of "what's going on" inside that company and need professional help. Usually, the problems are in the range of "low job satisfaction", low morale for employees and, as a result, poor production. The help which come from the Lean Six Sigma professionals would be to eliminate waste, streamline the internal and/or the external processes, while improving their output quality.

    Every good thing starts with a set of principles. It is known that Lean Software Development is world-wide used more and more. This is a methodology with the origins in Lean Thinking.
