Summary
“Application Lifecycle Management systems, or simply management systems are systems in which the entire lifecycle of a certain product or project are being managed. Such systems include the requirements, definitions, backlog and bugs and issue tracking aspect of the developed product. Most common systems are Jira (by Atlassian), TFS (by Microsoft) and Rally (by CA).”
With ALM, organizations can ensure applications are designed, built, tested and maintained effectively to meet their goals and user needs, from initial planning to decommissioning and retirement.
Implementing ALM systems provides the following organizational benefits:
- Enhanced product quality through continuous testing and feedback loops, by breaking down organizational silos, and by standardizing product processes.
- Better customer experience through faster time-to-market, streamlined processes, agile methodologies and clear communication with customers about retirement.
- Improving collaboration across development, operations, security and business functions.
- Visibility into progress, version history, performance metrics and end-of-life.
- Reduced resource waste.
- Enhanced security by seamlessly integrating security into development processes and into the application lifecycle.
What are the Stages of Application Lifecycle Management?
ALM defines the end-to-end process of managing an application’s life, from its inception to its eventual retirement. This includes:
1. Planning and Requirements Gathering – Understanding the purpose, goals and requirements of the application. This includes identifying business needs and objectives, gathering and documenting functional and non-functional requirements, developing a project roadmap with timelines and milestones, and risk assessment.
Deliverables: Requirement specifications, project plan and initial budget.
2. Design – Translating requirements into a blueprint for the application. This includes defining system architecture and application design, creating wireframes, mockups, or prototypes for UIs and selecting technology stacks, frameworks and tools.
Deliverables: Design documents, architecture diagrams, and prototypes.
3. Development – Building the application. This includes writing and compiling code, implementing version control and collaboration tools, secure coding and unit testing.
Deliverables: Functional application code, development documentation, initial builds, and a system for devsec feedback.
4. Testing – Ensuring the application meets quality, performance, and security standards. This includes unit testing, integration testing, system testing, performance testing, functional testing, API testing, security testing and more.
Deliverables: Bug reports, test cases, and a validated build ready for deployment.
5. Deployment – Releasing the tested application to production environments. This includes setting up the infrastructure, deploying and initial monitoring.
Deliverables: A live application and end-user documentation.
6. Maintenance and Support – Ensuring the application remains functional and up-to-date. This includes comprehensive monitoring, bug fixing, patching and updating features based on user feedback.
Deliverables: Patches, updates, and performance reports. This is the longest step of the process.
7. Decommissioning – Retiring the application when it becomes obsolete. This includes notifying stakeholders, migrating and archiving data as needed and removing the application from prod environments.
Deliverables: Archived data, decommissioning reports, and updated documentation.
Best Practices in Application Lifecycle Management
ALM ensures efficient management, high-quality outcomes, and alignment between the application and organizational goals. Here are best practices that will help achieve these benefits:
1. Align with Business Objectives
Ensure the application delivers value to stakeholders. To do so, involve business stakeholders as early as the planning phase to gather requirements. Then, define clear, measurable goals and success criteria for meeting those requirements. Incorporate the requirements in the early phases and track after deployment. Optimize if needed. Make sure to continuously review the application’s alignment with evolving business needs over time.
2. Implement Requirements Management
Avoid scope creep and costly rework by managing requirements systematically. Gather detailed, actionable requirements in collaboration with all stakeholders. Use tools like Jira or Azure DevOps to manage and track requirements. Maintain a single source of truth for requirement documents.
3. Use Agile and DevOps Methodologies
Improve collaboration, speed up delivery and enhance quality through iterative development and feedback loops. This is mostly relevant for the development, testing, deployment and maintenance phases. For example, implement CI/CD pipelines for automated testing and deployment and systematically gather customer feedback and add new requirements to development sprints.
4. Prioritize QA
High-quality applications enhance user satisfaction and reduce maintenance costs. Make sure to embed testing at every stage of development and in production, and use automated testing tools for regression, performance and security testing. By encouraging a “shift-left” testing approach you will be able to catch issues early in the development cycle, but don’t neglect “shift-right” testing either.
5. Include Application Security
Incorporate security measures into your existing ALM processes, since they are an essential part of any application. This includes creating guidelines for secure coding, architecture, and deployment, integrating automated security testing into CI/CD pipelines using application security tools like SAST, DAST, SCA, etc., establishing DevSec communication and collaboration, and more.

6. Prioritize Collaboration and Communication
Teamwork reduces misunderstandings and improves outcomes. Foster an open culture where team members feel comfortable sharing challenges. Support this through collaboration platforms, regular meetings to align teams and share updates, an anonymized email inbox for issues and a non-blame approach to mistakes and incidents.
7. Monitor and Measure Performance
Monitoring insights into application health will help ensure application quality and prioritize areas for improvement. After establishing KPIs (best practice #1) set up monitoring tools to track performance metrics like uptime, response time and error rates. Generate recurring reports and set times in your schedule to track them and identify issues that need your attention. In addition, set up automated thresholds that alerts when performance is below the minimal accepted requirements, and set up a response plan for what to do when that happens.
8. Plan for Scalability and Maintenance
Your application should be able to adapt to future demands to remain functional. This includes, for example, maintaining detailed documentation to simplify future updates and using scalable cloud infrastructure to handle growing workloads.
9. Prepare for Decommissioning Early
Ensure a smooth transition when the application is no longer needed. This will ensure customer satisfaction and retention, compliance purposes and better government. Document decommissioning plans as early as the planning phase. Archive critical data for compliance and reference. Communicate retirement plans to stakeholders and users in advance and explain what they need to do to ensure they don’t lose their systems and data.
Application Lifecycle Management FAQs
Why is ALM important in software development?
Application Lifecycle Management provides a structured framework for managing the entire lifespan of a software application, from inception to retirement. This ensures that development, testing, deployment and maintenance are effective, cohesive and aligned with business objectives. This holistic approach reduces inefficiencies and enhances collaboration across teams, ensuring that the software remains high-quality throughout the development lifecycle and that users’ needs are met, in production and through retirements.
How does ALM differ from Software Development Lifecycle (SDLC)?
While ALM and SDLC are related, they serve different purposes. SDLC focuses on the step-by-step process of developing software, covering phases like requirements gathering, design, coding, testing, deployment, and maintenance. It’s primarily concerned with the creation and delivery of a software application.
ALM encompasses a broader scope, addressing not just the development process but also the ongoing management and eventual retirement of the application. ALM integrates the SDLC but extends to include governance, portfolio management and collaboration across various departments.
Essentially, ALM provides a continuous lifecycle view, whereas SDLC is a subset that focuses on the build phase of the lifecycle.
What tools are commonly used in Application Lifecycle Management?
ALM tools are used facilitate its various stages. Tools cover aspects like version control, requirements management, deployment, source code management, testing, and more. Some of the most common systems are Jira (by Atlassian), TFS (by Microsoft) and Rally (by CA). The choice of tools typically depends on organizational requirements, development methodologies, and team preferences.
How does ALM support agile development methodologies?
ALM offers tools and processes that promote flexibility, collaboration, fast feedback and rapid delivery cycles. For example, ALM tools support iterative planning, continuous testing, CI/CD and continuous feedback. It is up to the organization to choose the extent of agility to incorporate in ALM processes.
What are the benefits of implementing ALM in an organization?
ALM enhances application quality, user satisfaction and developer productivity. This is achieved by thorough planning, and by standardizing workflows and tools, like development, testing, monitoring and deployment. ALM also breaks down silos between development, operations and business teams, provides greater transparency and control, and ensures that applications remain scalable, secure and aligned with business needs.
