Day in the Life Of (DILO)

Introduction: DILO

A Day in the Life Of (DILO) study is a Lean and process improvement tool used to capture and analyse how employees, teams, or roles spend their time during a typical working day. It provides a detailed view of activities, highlighting inefficiencies and opportunities for improvement.

Background

The DILO technique is widely applied in Lean Six Sigma projects to build a factual understanding of current work practices. By distinguishing between value-adding and non-value-adding activities, it helps organisations design processes that reduce waste and increase productivity. DILO studies are also valuable in change management, as they create awareness of how time is actually used versus how it is expected to be used.

Key Elements/Features

• Scope Definition: Identify the role or function to be studied.
• Observation or Logging: Record activities through shadowing or self-reporting.
• Activity Categorisation: Classify tasks as value-adding, necessary non-value-adding, or waste.
• Analysis: Summarise time allocation and uncover bottlenecks.
• Recommendations: Suggest improvements such as automation, reduced waiting, or streamlined meetings.

Applications/Examples

• Lean Projects: Establishing baselines for current-state process maps.
• Time Management: Supporting individuals in optimising daily routines.
• Process Mapping: Linking individual work to broader value streams.
• Change Management: Demonstrating inefficiencies to engage employees in improvement.

Relevance/Impact

DILO studies deliver concrete insights into work routines and inefficiencies that are often invisible. They empower employees to take ownership of improvements and form a measurable basis for before-and-after comparisons. For example, a DILO of a maintenance technician might reveal that only 30% of time is spent on actual repairs, prompting scheduling and stock changes to increase productive time.
