Week in the Life Of (WILo)

Introduction: WILo

Week in the Life Of (WILo) is a Lean and process improvement technique used to analyse how time and resources are spent within a role, team, or department. It provides a detailed snapshot of a typical working week, revealing how much effort is dedicated to value-adding work versus wasteful or low-value activities. WILo helps organisations understand real work patterns and identify opportunities for improvement.

Background

WILo was developed to make hidden inefficiencies visible by tracking daily work in a structured way. It is based on the Lean principle of focusing on value creation and eliminating waste (muda). By categorising activities into value-adding, necessary non-value-adding, and pure waste, teams gain a clear view of how effectively time is used. This method is often applied in Lean transformations, time management studies, and organisational redesign projects.

Key Elements/Features

• Purpose: To identify the proportion of time spent on value-adding versus non-value-adding tasks and highlight improvement opportunities.
• Method:
  1. Define Scope: Select the role, team, or process to study.
  2. Track Activities: Record daily tasks in time blocks (e.g., 15–30 minutes) over a full working week.
  3. Classify Work: Categorise each activity as value-adding, necessary non-value-adding, or waste.
  4. Analyse Results: Identify bottlenecks, duplication, or waiting times.
  5. Implement Improvements: Target changes such as automation, workload balancing, or process simplification.
• Outputs: Data-driven insights into workload distribution, inefficiencies, and improvement priorities.

Applications/Examples

• Lean Projects: Establishing a baseline before process improvement initiatives.
• Time Management: Helping individuals and teams optimise daily routines.
• Process Redesign: Identifying redundant approvals, rework, or delays.
• Change Management: Raising awareness of current practices and promoting engagement in improvement efforts.

Relevance/Impact

WILo creates visibility into how time is actually spent, enabling evidence-based improvement. It helps teams challenge non-value-adding activities, balance workloads, and focus on tasks that contribute most to customer value. By basing change on real data, organisations achieve greater efficiency, productivity, and employee engagement.
