Scaled Agile Framework is completely based on Lean-Agile Mindset which is combination of beliefs, assumptions, and actions of SAFe leaders and practitioners who hold the concepts of the Agile Manifesto and Lean thinking. Lean Thinking which is chiefly defined through SAFe’s ‘House of Lean’ and was derived from Lean manufacturing inspired by Toyota’s ‘Houses of Lean’. It was then applied to software products and solutions development. Implementation of any model targets to deliver value to its stakeholders/customers, hence, in the SAFe’s ‘House of Lean’, the top most thing is the GOAL: Value, then we have pillars on which this Goal stands. Optimize the Whole is a part of fourth pillar in the house of lean – Relentless Improvement. It talks about optimizing the organization and the development process as whole and not in parts. It encourages learning and growth through continuous retrospection and process improvements.
