What is ALM?
Application Lifecycle Management is the creation and maintenance of product until its lifecycle. It involves multiple process, tools and people working together.
Why it’s so important?
- A product is developed with multiple stakeholders involved such as system, software, design, code developer and tester.
- Standardized environment that everyone could use to communicate and collaborate
- Flow of requirements shall be inherited from one level to another level. Ie., information flow across V model
- Any change done at higher level will be notified to below level
- Monitor the progress and keep track of all changes
What is ALM used for?
ALM provides a framework for setting requirements and establishing processes, rules and methodologies before deploying software. Thus, it helps to develop, test and maintain the software.
What is ALM Process:
The ALM process is backbone of DevOps operation,
- Helps to set and manage requirements with the process established
- Supports in managing the compliance and standards
- Helps to control the access across the projects and documents
- Helps to maintain project planning and roadmap
- Maintains the source code repositories
- Maintains test documents, test environment and test results
- Finally helps in handling maintenance activities
Building Software Lifecycle
Requirement
- Gathering requirement from customer in form of ReqIF, RIF, PDF, XML, Excel or Word to User need document
- Writing High level system requirements for customer delivered requirements, by means of L3/L2 level Requirement Documents
- Breaking down of high level into detailed software requirement, by means of L1 Requirement Documents
Design
- Creating design document by means of Specification documents (UML tools like Enterprise Architect or Cameo)
- Allows to maintain model based design element created via Matlab Simulinks via Model document types
Planning
- Mangers plan the Release for delivery to customer
- Helps in creating new Change Request for implementable customer requirements
- Maintains the bug reports in the form of Problem Reports
- Categorize the collection of works from Change Request as Tasks
- Support ticket to get help from support team
Implementation / Maintenance
- Script developed to meet customer requirements shall be maintained in the form of Version Control
- Set of files used for internal testing, customer release maintained in the form of check-pointed backup
- Controls and monitor each and every changes to the file for a Task in the form of Change Package
Testing
- Requirements are validated by means of test cases
- Planning for collection of test cases in a session/test set for testing the software
- Updating the results of test cases done via EXAM, SIL, HIL, QAC, Polyspace, Tessy, Lint tools via test result editor or Test runs
- Executing the test plan and validating the test report
