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.
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.
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.
