Resource Utilization Trap

In many organizations, the people who do the work are treated like economic resources (think: iron ore) and it’s felt that they have a price, and so must be utilized to maximize their value. Except these resources are actually human beings. Labelling it “human resources” is far more ironic than helpful.

Thinking of people as resources reduces them to common, replaceable parts. It also leads to the mindset that, to deliver the most value, they must always be busy. This is known as the Resource Utilization Trap. People aren’t machines or assembly lines, and if they always look busy, much of their work will be low value.

• With the emphasis on busyness, quality is sacrificed. The team look to ensure that they’re seen ticking off tasks from their list. Whereas things that improve quality (e.g. pair programming, improving simplicity, refactoring, etc. See: Agile Engineering Practice), don’t show up on task lists and so lose focus.
• Bottlenecks ensue when tasks wait for a team member who is already busy (or utilized) on another task.
• Both Cycle Time and Lead Time get worse.  The bottlenecks ensure that most work items take longer to complete. When quality is harmed, there are more defects. As the number of defects goes up, the team spend more time solving bugs than building new things, and so the Cycle Time increases.
• **Throughput or Velocity will also decrease.**
• There is minimal, or no, improvement. Process Improvement and learning requires time for reflection, experimentation and learning. A focus on busyness, doesn’t leave room for improvement.
• Dealing with innovation and complexity requires slack. The slack is used by team members to adapt as the work evolves. Complex problems and innovation require dealing with a large amount of uncertainty. Without room to manoeuvre, teams generally stop innovating altogether.

Organizations that focus on utilization and busyness are not resilient. These groups struggle to adapt when faced with change. The problem is often further compounded by violating the core constraint of Scrum that says team members can be a member of only one team.
