Deliverable
Any unique and verifiable product, result, or capability that must be produced to complete a process, phase, or project.
Breaking down the definition
Lets break this definition down so we can better understand its meaning, particularly the concept of being "verifiable."
Unique: A deliverable is distinct and specific to the project at hand. It isn't a generic output but something tailored to the needs and objectives of the particular project. The Project Management Body of Knowledge (PMBOK) notes that repetitive elements may be present in some project deliverables, but this repetition does not change the fundamental, uniqueness of the project.
Verifiable: This is a critical aspect of the definition. A deliverable being "verifiable" means that it can be measured, tested, or validated in some way to ensure it meets the required standards or specifications. Verification is the process of confirming that the deliverable has been produced according to the predefined requirements and is of the expected quality. This could involve various methods depending on the nature of the deliverable, such as:
Testing: For a product or software, testing could be used to verify that it functions as intended.
Review and Approval: Documents or plans might need to undergo a review process and be approved by relevant stakeholders.
Inspections or Audits: Physical constructions or organizational processes may be verified through inspections or audits.
Performance Metrics: For results like increased sales or improved performance, verification could involve comparing against specific metrics or KPIs (Key Performance Indicators).
Product, Result, or Capability:
Product: a tangible item like a machine, or intangible like a behaviour change.
Result: outcomes or benefits derived from the project, such as increased efficiency, market research findings, or educational achievements.
Capability: a new ability or capacity developed as a result of the project, like enhanced skills or new processes.
To Complete a Process, Phase, or Project: deliverables are essential for the progression or completion of a specific stage or the entire project.
In summary, a deliverable in project management is not just any output; it must be distinctive, confirmable through some form of validation, and crucial for the successful completion of a particular stage or the entire project. This ensures that all efforts are aligned towards producing outcomes that can be demonstrably shown to meet the project's goals and requirements.
The Role of Deliverables in the Work Breakdown Structure (WBS)
The Work Breakdown Structure (WBS) is a foundational tool in project management, used to divide and conquer the scope of a project. Deliverables play a pivotal role in structuring the WBS, serving as the primary building blocks for breaking down the project work.
How Deliverables Structure the WBS
The Work Breakdown Structure is structured by the project deliverables, with the major deliverables broken down into Work Packages.
In the WBS, a project is decomposed into smaller, more manageable components, with each level providing a more detailed breakdown of the work required. At the highest level of the WBS, the major deliverables are identified. These deliverables represent the significant outputs or results that the project is committed to producing. By focusing on deliverables rather than tasks, the WBS aligns the project team and stakeholders around clear, tangible outcomes, ensuring a results-oriented approach to project management.
Each major deliverable is then further broken down into smaller elements, eventually reaching a level of granularity where the work can be easily assigned, estimated, monitored, and controlled. This hierarchical decomposition of deliverables into smaller work packages is fundamental to effective project planning and execution.
