What is a Work Package in Project Management?

A work package is a subset of the total scope of work required to complete a project. Work packages represent the most granular level of the work breakdown structure (WBS), breaking down high-level deliverables into smaller, more manageable components.

While a deliverable may be big and broad, a work package contains a specific set of work that must be done to complete part of a deliverable. Work packages are essentially mini-projects within the larger project.

Some key characteristics of work packages include:

• They are derived from higher WBS levels and represent the work required for a deliverable.

• They contain a definable amount of work that can be assigned and managed.

• They have a defined start and end date and measurable deliverables.

• They have an assigned budget and resource requirements.

• They can be monitored for progress and completion.

In summary, a work package is a clearly defined unit of work to be done as part of a project. It is the smallest component of a project that can be planned, managed, monitored and controlled.

Why Are Work Packages Important for Project Management?

There are several key reasons why developing and managing work packages is so critical for project management success:

Work Packages Break Down Project Scope

One of the biggest benefits of work packages is that they provide a structured way to break down the overall scope of a project into manageable chunks. This supports more accurate estimating, scheduling, resource planning and budgeting.

By breaking project deliverables down into work packages, you gain greater visibility into the effort needed and can more easily track progress. This ensures important project work doesn't get missed.

Work Packages Enable Better Planning

Work packages are essential for project planning activities like creating a realistic schedule, estimating costs, and planning resources.

You can use work packages to identify work dependencies that impact scheduling. Having defined work packages also allows you to more accurately estimate the effort and resources needed.

Overall, work packages give you the detail you need for more precise planning and scheduling. This leads to more attainable project plans.

Work Packages Support Effective Task Execution

Another major advantage of work packages is that they provide a structure for executing tasks efficiently.

Work packages can be easily assigned to team members, clarifying responsibility and accountability. Their defined scope and end goals support focus. Team members understand exactly what must be delivered and can work semi-autonomously to complete their work package assignments.

This delegation of work in packages leads to faster and higher quality task execution.

Work Packages Enable Better Monitoring and Controlling

Work packages are invaluable for monitoring and controlling project work. Their progress and completion metrics allow you to regularly assess status.

This visibility into work package progress versus plan makes it easier to identify delays or issues early. You can then take any necessary corrective actions to keep the project on track.

Work packages also integrate seamlessly with earned value management, a project performance measurement technique. More on this benefit later.

Work Packages Improve Communication

Detailed work packages allow for better collaboration and communication within project teams.

When team members have clarity on work package objectives, scope, timelines and standards, they can work together more efficiently. Work packages essentially provide a shared roadmap.

Well-defined work packages also facilitate better communication with stakeholders. You can clearly articulate status by work package to demonstrate progress and flag any needs for adjustment.

In summary, work packages provide a crucial structure for planning, executing, monitoring, controlling and communicating project work. Leveraging them effectively is key to project management success.

How Do Work Packages Relate to the Work Breakdown Structure?

To use work packages, it's important to understand their relationship to the work breakdown structure (WBS). The WBS is a hierarchical decomposition of all project deliverables into manageable work components. It divides the total scope of work into layers, with each layer providing more detail.

Work packages represent the most granular layer of the WBS. They break high-level WBS elements like deliverables down into bite-sized pieces of work.

While the WBS provides the overall structure, work packages contain the actual tasks and activities to be executed. Every work package should roll up into a parent WBS element.

For example, if a house construction project has a WBS deliverable for "Build Foundation", the related work packages would represent the actual work needed like "Pour Concrete Footings" and "Construct Foundation Walls."

So in essence, the WBS allows you to organize the full scope of work, while work packages detail the required tasks within each WBS element. The WBS and work packages work together to provide a complete picture of project work.

Best Practices for Developing Work Packages

Careful development of work packages is critical for reaping their benefits. Here are some best practices to follow when creating work packages:

• Break down deliverables into logical pieces - Leverage the WBS to divide high-level deliverables into related work package groupings that make sense. Similar work should be bundled.

• Make work packages a manageable size - Work packages should represent between 40-80 hours of effort on average. Too large or small makes monitoring and managing difficult.

• Define clear scopes and objectives - Every work package should have a well-defined objective and scope of work to support execution.

• Include required resources - Identify the labor, equipment, and materials needed to complete the work package.

• Estimate duration - Estimate the time required to complete the work package, leveraging past data.

• Determine dependencies - Identify predecessor and successor work packages that impact scheduling.

• Assign ownership - Assign each work package an owner responsible for completion. This provides accountability.

• Monitor ready for start - Ensure prerequisites are complete before starting work on a package.

Following these best practices will help you develop work packages that set your project up for success.

Tips for Managing Work Packages Effectively

Once you've developed your project work packages, you need to manage them closely throughout project execution. Here are some tips for effective work package management:

• Review work package status regularly in team meetings. Assess progress against the baseline plan.

• Act quickly on any work package delays or issues. Develop a course correction when needed.

• Verify work package completion and quality before closing. Have the owner sign-off.

• Update the project schedule as work package statuses change. Reflect reality.

• Keep work package documentation current. Record any scope or resource changes.

• Monitor overall work package health. Watch for trends that could impact the project.

• Control changes tightly. Follow a change control process for any work package changes.

• Communicate work package status clearly to stakeholders. Increase visibility.

These work management disciplines will help you deliver each package successfully and gain maximum value from your upfront planning.

Integrating Work Packages with Earned Value Management

Earned value management (EVM) is a project performance and progress measurement technique that integrates extremely well with work packages.

EVM looks at schedule and cost performance together by combining 3 key metrics:

• Planned Value (PV) - The budgeted cost of work scheduled to be completed by a certain point.

• Earned Value (EV) - The budgeted cost of work actually completed.

• Actual Costs (AC) - The actual costs incurred for work done.

By comparing PV, EV and AC you can objectively assess schedule and cost performance. Work packages make measuring EV easier - when a work package is complete, you can mark its budgeted amount as EV.

So EVM leverages the planning foundation provided by work packages to support performance measurement and management. It adds crucial visibility into schedule and budget adherence at the work package level.

Integrating work packages and EVM methodology provides the detail needed to catch performance issues early and course correct. It's a best practice for controlling project work.

Key Takeaways and Summary
