The Power of Activity and Project Networks: Ensuring Timely Completion

Share this resource:

Activity networks, sometimes called project networks, are like roadmaps for projects, providing a visual representation of tasks and their dependencies. They help in understanding the big picture, planning effectively, and ensuring the timely completion of projects.

What are Activity Networks?

Activity networks are diagrams that map out all the tasks involved in a project and how they connect. Imagine you’re building a treehouse. Tasks like gathering wood, designing the structure, and assembling pieces must happen in a certain order. An activity network visually organises these tasks and their dependencies, showing the sequence of activities required for project completion.

Key Terms in Activity Networks

  1. Activity Network: A diagram representing project tasks and their dependencies.
  2. Precedence Table: Lists tasks and their immediate predecessors, showing task dependencies.
  3. Dummy Activities: Arrows in the network clarifying dependencies when multiple activities share some, but not all, predecessors.

Building an Activity Network: A Practical Example

Let’s plan a surprise birthday party as an example. We have tasks like baking the cake (A), decorating the venue (B), buying supplies (C), setting up decorations (D), picking up the birthday person (E), and guests arriving (F).

  • Start by drawing a start node and arrows for tasks without predecessors.
  • For tasks with predecessors, draw arrows from the completion of those tasks.
  • Use dummy activities when multiple tasks share some, but not all, predecessors.

Real-World Applications of Activity Networks

Activity networks are used in various fields:

  • Construction: Planning tasks from foundation laying to fixture installation.
  • Software Development: Outlining steps in coding, testing, and deployment.
  • Event Planning: Ensuring smooth coordination from venue booking to catering.
  • Everyday Life: Implicitly used in trip planning, wedding organisation, and daily routines.

Mastering Activity Networks for Success

By understanding and utilising activity networks, we empower ourselves to:

  • Plan effectively, identify critical tasks, and ensure timely completion.
  • Build accurate networks using precedence tables and dummy activities.
  • Navigate complex projects with confidence and achieve successful outcomes.

Embrace the power of activity networks in project management to transform your approach, increase efficiency, and reduce the risk of delays.
