RACI Matrix

The RACI Matrix is a chart used to determine who is responsible for what. In software development projects, it’s far too easy for tasks to fall through the cracks because everyone assumes someone else is handling it. RACI addresses that by giving every task a clear set of "owners." 

RACI stands for Responsible, Accountable, Consulted, and Informed. Here is how that breaks down:

Responsible: 

This is the person (or people) actually doing the graft. They are the ones with their hands on the keyboard or the tools.
Example: If the task is "Write the automation scripts," the Testers or SDETs are responsible. You can have more than one person in this bucket.

Accountable: 

This is the most important one. The Accountable person is the one who has to answer for the work if it goes wrong and signs off on it when it’s right.
The Golden Rule: You can only have one Accountable person per task. If you have two, you have none. It’s about having clarity to ensure things actually get finished to the right standard.

Consulted: 

These are the people you need to talk to before or during the task. They have the expertise or the context you’re missing. It’s a two-way street—you ask for their input, and they give it.
Example: If you’re setting up a new test environment, you’d consult the DevOps team to make sure you aren't about to break the network.

Informed: 

These folks just need to know the result. They don't need to help or give permission. They just need a heads-up once the job is done. This is one-way communication.
Example: Once a release is live, the Customer Support team is informed so they know what to tell users if they get a call.

RACI isn't just about bureaucracy. When a team knows who is driving (Responsible) and who is ultimately answering for the journey (Accountable), decisions get made faster, and there’s less "blame game" when things get tricky. It’s a simple way to build TeamEx by removing the friction of ambiguity.
