Work Content (WC)
WC = Time of Value Added throughout the process.
Total WC = Sum of Time of all activities that add value
Waste Elimination in Business Processes

• Eliminate bureaucracy • Eliminate duplication
• Simplify
– – – Combining similar activities Re-sequencing of steps for smoother flow Rearranging data in a more user-friendly format
Required Output: Product or Service
Business Processes are similar to Manufacturing Processes – Both typically have Non Value Added Activities (Waste) and disruption to flow (Inventory/ Delays)
• Error-proof the process
• Reduce process time
– – – – Performing activities in parallel instead of sequentially Reducing interruptions (especially in bottleneck areas) Eliminating redundancy Eliminating loops
• Identify and eliminate non-value added activities
• Standardize
