Software configuration management (SCM) is a process that helps you track and control changes in your software, from the initial design to the final deployment. SCM can help you improve your productivity, quality, and collaboration with your team members and stakeholders. But how can you master SCM in a simple and effective way? Here are five easy steps that you can follow to become a SCM pro.
Step 1: Identify your configuration items
The first step in SCM is to identify your configuration items (CIs), which are the components of your software system that you want to manage and control. CIs can include source code, documentation, test cases, configuration files, libraries, tools, and more. You should give each CI a unique name and version number, and store them in a central repository, such as Git, SVN, or Mercurial. This way, you can easily access, update, and track your CIs throughout the software development life cycle.
Step 2: Establish baselines
The next step in SCM is to establish baselines, which are snapshots of your software system at a certain point in time. Baselines can help you define the scope, requirements, and deliverables of your project, and serve as reference points for future changes and releases. You should create baselines at key milestones of your project, such as the start, end, or review of a phase. You can use tools like Docker, Terraform, or Ansible to create and manage your baselines in a consistent and automated way.
Step 3: Implement change control
The third step in SCM is to implement change control, which is a process that regulates and documents the modifications to your software system. Change control can help you prevent errors, conflicts, and inconsistencies in your software, and ensure that only authorized and approved changes are implemented. You should set up a change control board (CCB), which is a group of people who are responsible for reviewing and approving change requests. You should also use tools like Jira, Trello, or Asana to track and manage your change requests, and tools like GitHub, Bitbucket, or GitLab to implement and review your changes.
Step 4: Perform configuration status accounting
The fourth step in SCM is to perform configuration status accounting, which is a process that records and reports the status and history of your software system. Configuration status accounting can help you monitor the progress, performance, and quality of your software, and provide visibility and transparency to your team members and stakeholders. You should use tools like Jenkins, Travis CI, or CircleCI to automate and integrate your build, test, and deployment processes, and tools like SonarQube, Codecov, or Codacy to measure and improve your code quality and coverage.
Step 5: Conduct configuration audits and reviews
The fifth and final step in SCM is to conduct configuration audits and reviews, which are processes that verify and validate the correctness and completeness of your software system. Configuration audits and reviews can help you ensure that your software meets the specifications, standards, and expectations of your project, and identify and resolve any issues or defects. You should conduct configuration audits and reviews at regular intervals, such as before or after a release, or during a phase transition. You should also use tools like Selenium, Cucumber, or Postman to automate and execute your functional and non-functional tests, and tools like Slack, Zoom, or Teams to communicate and collaborate with your team members and stakeholders.
