What are the tools and techniques for creating and updating a dependency matrix?

1 Why use a dependency matrix?

A dependency matrix can be a valuable tool in sprint planning, offering several benefits such as clarifying the scope and requirements of each task or feature, identifying potential risks that may affect delivery, aligning expectations and commitments of your team and stakeholders, optimizing resource and time use, and tracking and communicating progress and status.

2 How to create a dependency matrix?

Creating a dependency matrix involves several steps, such as assigning a unique identifier and short description to each item, listing them in a table or grid, and marking the dependencies between the items. Additionally, you need to indicate the type and direction of the dependencies, such as finish-to-start, start-to-start, finish-to-finish, or start-to-finish. Furthermore, you may want to add any additional information that may be relevant, such as priority, owner, due date, or status.

3 What are some examples of dependency matrix tools?

Depending on your needs and preferences, you can use different tools to create and update your dependency matrix. Spreadsheets, such as Excel or Google Sheets, can be used to create a simple and flexible matrix, while formulas, filters, and conditional formatting can be used to automate and customize it. Alternatively, a diagramming tool like Visio or Lucidchart can be used to create a graphical and interactive matrix with shapes, lines, and icons. Lastly, a project management software like Jira or Trello can be used to create a digital and collaborative matrix with features such as cards, boards, labels, and links.

4 How to update a dependency matrix?

A dependency matrix is not a static document, but a dynamic and evolving tool that reflects the changes and progress of your project. Therefore, it is essential to keep it up-to-date by regularly and consistently reviewing the status and completion of each item, updating the dependencies and information, resolving any conflicts or issues, communicating the changes and updates to your team and stakeholders, and adjusting your plan and actions based on the updated matrix.
