SDLC is primarily focused on the development phase.
ALM is concerned with the entire application life cycle. (governance, development, and maintenance)
eg:
- Jira is an enterprise-grade ALM tool with features to manage complex application lifecycles.
- TFS is a Microsoft tool that we should use to implement ALM, while as mention before it's a part of Visual Studio Team System.
Project governance is the management framework within which project decisions are made. The accountabilities and responsibilities associated with an organization's BAU activities are laid down in their organizational governance arrangements.
In software engineering, a software development process is the process of dividing software development work into smaller, parallel or sequential steps or subprocesses to improve design, product management. It is also known as a software development life cycle (SDLC).
(Most modern development processes can be vaguely described as agile. Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming.)
A common perception of maintenance is that it merely involves fixing defects. However, one study indicated that over 80% of maintenance effort is used for non-corrective actions. This perception is perpetuated by users submitting problem reports that in reality are functionality enhancements to the system.
ALM vs PLM <link to plm>
ALM is focused solely on software development and the lifecycle of an application, while PLM encompasses the entire product lifecycle, including design, development, manufacturing, distribution, and service. Complexity – Because PLM covers a broader range of activities, it is typically more complex than ALM.
