Unveiling Value: A Qualitative Analysis of Process Efficiency

As we set out on the process improvement journey, it is important to visualize how it all looks like from the customer’s perspective. Be it in the information-rich process descriptions or Visual Stream Mapping in the current state, this is all centered around figuring out where the ‘added value ‘ is and establishing the lurking wastes that are embedded within processes. Indeed, it is a waste that is ultimately the root cause of the problems we are experiencing.

Understanding Value Added, Business Non-Value Add, and Non-Value Added

When disassembling the VSM or any other process depiction, we provide a list of acronyms to the steps to help us appropriately. The categorization includes:

  1. Value Added (VA): It involves the creation of worth directly.
  2. Business Non-Value Add (BNVA): The operations are vital, but not directly adding value.
  3. Non-Value Added (NVA): These form the wastage, or muda, of the process.

Waste Identification in Lean Methodology: Key Considerations and Questions

Lean methodology promotes the elimination of all kinds of wastes, including but not limited to the notorious 8 types of muda, variations – Mura, and overburden – Muri. The data collection and analysis start with waste identification and the following meaningful questions:

  1. Does this step bring value that is material – If not, should it exist, and can it be eliminated.
  2. Are there supplies or work in progress accumulations.
  3. Is its outcome unusable products or waste.
  4. Does this step perform as desired.
  5. Are tools and materials within reach and properly accepted.
  6. What is its cycle time relative to its capacity.
  7. Is it causing people to wait.
  8. How does the process handle time switching between products or services.
  9. Can the switching flow be smooth, or is this step a bottleneck?

Finally, it is crucial to comprehend the connection between process time and customer demand. During the root cause identification phase, it is necessary to prioritize. Make sure to rank the causes according to their influence on the identified problem, using the shared knowledge from the team.
