How Dependencies Affect Capacity Planning

Imagine this: your team is ready to deliver a big project. Everyone has their tasks assigned, hours estimated and everything seems to be on track. Then all of a sudden, things stall. Why? Dependencies.

Dependencies are the hidden threads in every project. They’re not always obvious when you’re looking at the list of hours or tasks. Yet, ignoring them can make even the most carefully planned go to waste.

In capacity planning, dependencies refer to any tasks, resources, or external factors that your work relies on. Some common examples:

• - Task dependencies: Task B can’t start until Task A is finished.
• - Resource dependencies: A designer can’t start a mockup because the copywriter hasn’t delivered content.
• - External dependencies: Waiting on the approval from a client or vendor.
• - Skill-based dependencies: Only certain people can perform a specific task.

Even if you think your team has enough hours in a week, dependencies can make those hours meaningless if they’re not properly accounted for.

Capacity planning usually starts with the assumption that resources are independent. In reality, work is rarely independent. Dependencies create bottlenecks that you can’t notice simply by looking at the calendar.

Some ways this happens:

• 1. Invisible delays: One delayed task can have a domino effect on the whole team. Certain people are waiting instead of working, and your “full” capacity is wasted.
• 2. Overloaded key resources: When only a few people can do a task, their availability becomes crucial for the continuation of work. Even if others have free hours, work can’t progress.
• 3. Missed priorities: Dependencies often make teams react instead of plan. Last-minute changes can affect plans and priorities.

In short, ignoring dependencies might seem like filling a bucket that has holes: it might look full, but the water is constantly leaking.

You can plan around dependencies and here’s how you can do that:

• 1. Map out your dependencies early
  Before estimating capacity, make a simple dependency map. Who or what needs to finish before work can start? Identify both internal and external blockers.
• 2. Plan for “buffer capacity”
  If a task can’t start until someone else finishes, some team members might end up waiting. Leave extra time in the plan for these waiting periods instead of scheduling everyone at 100%.
• 3. Prioritize critical dependencies
  Some dependencies matter more than others. Identify the tasks that could cause the largest domino effect if delayed. Give those tasks the highest priority so they can be finished on time.
• 4. Use cross-team visibility
  Many dependency issues happen across teams, so make sure to see the other team’s workload. Tools like CapaPlanner help you visualize capacity and dependencies across multiple teams. This way, you can forecast workload peaks before they happen.
• 5. Monitor and adjust in real-time
  Dependencies are dynamic. A task might get delayed, or a resource becomes unavailable. Track your capacity daily and adjust your plan as things change.

Dependencies aren’t small details; they can totally change your plans. A team might be fully utilized but then hidden dependencies can leave work idle and projects delayed. By mapping, prioritizing, and monitoring dependencies, you can make capacity planning more realistic and actionable.

While thinking about dependencies might seem like extra work, it saves time in the long run. There are always tools you can leverage, i.e. CapaPlanner, which make the whole process much easier.
