Understanding Task Types

Modified on Wed, 12 Jun at 5:38 PM

Understanding the different types of scheduled tasks is fundamental for effective time management and task prioritisation in project management. Differentiating between task types such as phase, deliverables, workstreams, actions and milestones is crucial for several reasons: 

  • Clarity and Structure: Each task type serves a unique purpose, providing clarity and structure to the project plan. For instance, phases divide the project into large, manageable sections, while actions break down these sections into specific tasks. 
  • Progress Tracking: Differentiating between task types allows for precise progress tracking. Milestones, for example, mark significant points of achievement and help monitor whether the project is on track, while deliverables ensure that tangible outcomes are being met. 
  • Prioritisation and Focus: Different task types help in prioritising work. Actions and deliverables might require immediate attention to ensure phases and milestones are completed on schedule. This helps in maintaining focus and ensuring that critical tasks are not overlooked. 

This article provides a comprehensive overview of the task types that can be selected in a schedule or project plan, essential for creating a structured and efficient project workflow.

Schedule Task Types

Each task type plays a specific role in project management, contributing to the overall success of the project. Below, we delve into the characteristics and applications of each task type, supported by practical examples.



  • Definition: Phases are distinct periods in the project lifecycle that represent a group of related activities or tasks necessary to achieve a specific set of objectives. 
  • Characteristics: They help to organise and manage the project by breaking it down into more manageable parts, each with its own focus and goals. Phases often conclude with a review or a milestone, ensuring that all necessary work has been completed before moving to the next stage. 
  • Example: In a Cloud Migration project, phases might include Planning, Data Profiling, Data Backup, Migration Design, and Execution. Each phase must be thoroughly completed and reviewed before progressing to the next, ensuring a systematic approach to the project.


  • Definition: Workstreams are parallel tracks of activities or tasks that progress concurrently within a project.
  • Characteristics: Each workstream is dedicated to a specific domain or aspect of the project. This approach enhances specialisation, allowing for focused expertise and efficient execution of tasks. Workstreams typically have their own set of deliverables and milestones, contributing to the broader project objectives. 
  • Example: In a Construction project, workstreams could be categorised by activities such as Site Preparation, Foundation, Structure, Plumbing, and Electrical. Each workstream operates independently yet synchronises with the overall project timeline to ensure cohesive progress and successful project completion.


  • Definition: Deliverables are tangible, measurable outcomes or results produced upon the completion of specific phases or workstreams. 
  • Characteristics: These are the critical outputs that represent the achievement of project objectives. Deliverables must be well-defined, with clear criteria for completion to ensure quality and alignment with project goals. They serve as key benchmarks for evaluating project progress and success. 
  • Example: In a sustainable energy development project, deliverables might include comprehensive site assessments, detailed compliance reports, procurement of materials, and the construction of infrastructure. These deliverables are essential for ensuring the project meets regulatory standards and achieves its intended outcomes.


  • Definition: Actions refer to specific, discrete tasks or activities that need to be completed to achieve a deliverable or advance the project. 
  • Characteristics: Actions are granular and detailed, forming the essential building blocks of larger workflows. Each action should have a clear objective, assigned resources, and a timeline for completion. Effective action management is crucial for maintaining project momentum and ensuring timely progress toward deliverables and milestones. 
  • Example: In a data centre development project, actions might include drafting architecture plans, conducting design reviews, and implementing security measures.


  • Definition: Milestones are strategically significant points within a project timeline that denote the completion of major deliverables or phases.  
  • Characteristics: Milestones represent key achievements and are used to monitor progress, ensuring the project stays on track. They enable project managers to exert greater control over the project lifecycle, facilitating timely interventions and adjustments. As vital communication tools, milestones provide clear checkpoints for reporting to stakeholders, ensuring transparency and alignment throughout the project. Additionally, by setting short-term goals, milestones help maintain momentum and boost morale within the project team. They also assist in identifying and mitigating risks early by ensuring that key deliverables are met before moving to subsequent phases. 
  • Example: In a new training website launch project, key milestones could include Securing application approvals, Completing content upload and Official website launch.
