Guided Lab: Source Control and Change Management in DevOps Foundations
DevOps Foundations — Source Control and Change Management lab: Map a small change from commit through build/test to a disposable deployment, record wait/failure points, and automate one manual verification step.
Outcome summary
Know what success looks like before you begin
Save verification evidence: the module-specific command, output, test, rendered state, query result, log, or measurement that proves the exercise worked.
- I completed the module-specific practice task.
- I produced a working source control and change management exercise with a documented technical result.
- I saved the module-specific command, output, test, rendered state, query result, log, or measurement that proves the exercise worked.
- I diagnosed and corrected one realistic Source Control and Change Management failure.
Stop before using production credentials, important data, shared permissions, live infrastructure, or destructive commands that are not required by the lab.

Lab brief
Know the problem and the evidence you need
Map a small change from commit through build/test to a disposable deployment, record wait/failure points, and automate one manual verification step.
a working source control and change management exercise with a documented technical result
Complete the task, verify the module-specific command, output, test, rendered state, query result, log, or measurement that proves the exercise worked, then diagnose one failure that is specific to Source Control and Change Management.
Shorten and stabilize the path from code change to user value by versioning changes, automating build/test, treating infrastructure as code, measuring reliability, and improving from feedback.
Safety and setup
Prepare before changing anything
Have this ready
- Open a small local project or disposable lab environment.
- Confirm the runtime, toolchain, or service needed for the module.
- Prepare one valid input and one invalid or boundary input.
Field checks
0 of 5 checks completeRun the lab
Complete one check at a time. Record the evidence before moving on.
Interpret results
Match the evidence to the next action
If you seeNext action
The expected result appears and the boundary case behaves correctly
Save the result and continue to the module checkpoint.
The normal case works but the failure or boundary case does not
Return to the diagnostic step and inspect the module-specific state or output before changing more code.
The result changes between runs
Compare the relevant input, dependency, configuration, data, state, or runtime version for this module.
Choose the next action
Complete the lab when you can reproduce the working result, explain the important module decision, and recover from the tested failure.
