See the Whole
The 'see the whole' principle expands on the concept of examining the whole system not just individual sections when making decisions or changes. This approach encourages a comprehensive understanding of the overall system or workflow, taking into account every operation and process rather than viewing them in isolation. It brings attention to inefficiencies that may arise when processes are optimized separately, creating 'local optimizations' that could potentially harm the overall system. This principle emphasizes the importance of seeing a project from a larger perspective avoiding a concentration on a specific phase, feature or function.
Guide: See the Whole in Lean Software Development (PMI-ACP)
In the context of PMI-ACP (Project Management Institute Agile Certified Practitioner) and Lean Software Development, 'See the Whole' is about understanding the entire process and how the individual parts interrelate.
Why is it Important?
'See the Whole' is critical in Lean Software Development to avoid sub-optimization, where optimizing one part of the system actually causes poorer performance in the whole system. It promotes holistic thinking and decision-making.
What is it?
'See the Whole' is a lean principle that entails looking at the entire value stream or system, rather than focusing on individual components or steps.
How does it work?
This concept works by applying systems thinking, viewing the project or process as a unified whole instead of separate parts. Steps include mapping the value stream, identifying inefficiencies and reevaluating regularly.
