Application lifecycle management (ALM) is the process of conceiving, developing, deploying, managing, maintaining and retiring software applications.
ALM involves DevOps and business teams working together for the entire application lifecycle to deploy and deliver functioning applications that meet business objectives. It encompasses numerous related disciplines including requirements management, computer programming, software development, software testing and maintenance, change management, continuous integration, project management and more.
Application development is a collaborative process that works best when all stakeholders have visibility into the process. ALM tools streamline the creation of applications through a defined methodology intended to create quality products. Application lifecycle management tools help IT operations automate processes and workflows that lead to faster deployment and better maintenance throughout the application lifecycle.
Implementing a successful application lifecycle management strategy requires an understanding of the stages of ALM and the creation of a clear strategy and plan for development, deployment and beyond. For a successful product launch, teams must treat every step of the process with equal importance. Because organizations are increasingly reliant on applications to achieve business objectives, it's important to have tools and technologies that can help deliver apps that meet users' needs.
There are five stages of application lifecycle management, each requiring a separate set of tools and expertise to effectively achieve. Project managers must also define a workflow for ALM. Two common workflows include:
In the first stage, stakeholders clearly define why they need an application and what business use cases it solves. Stakeholders identify intended users, plan the design of the application user interface, and consider legal compliance standards. Having a detailed and holistic understanding of business requirements during this stage can help avoid bottlenecks down the line.
During this phase, project managers draft timelines, set clear responsibilities for different teams, and establish clear pathways of communication.
Once the application requirements are made clear, development teams begin building the application. Though the development phase is highly technical, business teams, including product marketing and sales teams, should remain involved to make sure the product meets the wanted objectives. Teams establish timelines and requirements for testing during the development stage.
When the application is built, robust test cases make sure that the product meets business and regulatory requirements, including security and privacy requirements. Testers bring bugs or errors discovered during the process to the development team. Business team members should also be involved in the testing phase to ensure that the application meets expectations.
Test management and DevOps teams employ continuous integration (CI), a process that automates the building and testing of new code. CI helps developers integrate new code and quickly identify any issues. Testing and quality assurance should continue once a product is deployed.
After the sufficient testing of an application, it is deployed to users. Part of the release management plan involves a defined structure for maintenance and making future updates to the application. After release, the application requires constant monitoring to maintain application health.
When applications are released, they encounter real users and use cases that might create errors or flaws that were not identified before deployment. Application performance management software and solutions help enterprises monitor application performance in real-time. Configuration management tools help maintain the systems, servers and devices that run applications. This helps organizations meet business objectives and enhance user experience.
Also, new technologies or business cases might require updates to existing applications. DevOps teams often deploy continuous delivery (CD) pipelines to automate the process of maintaining and automating apps. When a developer creates new code for an application, continuous delivery solutions automate the process of creating a testing environment for the new code. If new code meets the testing requirements, it is automatically deployed. CD enables teams to make updates and correct errors more quickly, which reduces application downtime.
When implemented correctly, ALM streamlines the process of application and software development while making sure that all stakeholders have input.
Development and maintenance tools used in application lifecycle management help DevOps teams better streamline and automate the process of developing, deploying and monitoring new applications.
ALM solutions offer end-to-end tools for the creation and management of applications. These tools, often deployed as SaaS (software as a service) or cloud-based solutions, help manage the increased number of applications that enterprises rely on. Governance tools offer project managers solutions for maintaining communication and feedback loops across teams.
They also provide ways to organize the requirement management process, which helps ensure that organizations meet all business objectives while creating estimated timelines and cost analysis for any particular project. ALM tools provide greater visibility into the application lifecycle, which helps break down silos and allow for more efficient application production.
Two of the main challenges in implementing ALM processes are efficient scalability and consistent visibility. Deploying updates, fixes and new code across a complex system of applications while providing continuous service to users is a difficult task.
This task becomes more challenging when applications and workloads are distributed across multicloud and hybrid cloud platforms, and critical aspects of application management, such as compliance, are siloed to specific departments with their own subject matter experts. These silos can make it difficult to make real-time updates to an application while maintaining compliance, performance and other key factors.
To overcome such challenges, organizations must implement ALM solutions that provide visibility across various departments and insights that team members with different fields of expertise can understand. ALM solutions integrate existing tools and platforms to give users a centralized view of data.
Monitoring the lifecycle of applications, software or other technology means managing it from conception to end of life. There are a few other development methodologies that use the term “lifecycle” including software development lifecycle and product lifecycle management. There are differences between theses processes, and the terms should not be used interchangeably. A quick break down of how they differ:
This process refers to the methodology used to build high-quality software. Software development teams focus on the technology, testing and deployment of a specific piece of software. SDLC is one of the stages of application lifecycle management, which focuses on the software development process. ALM is a broader term that involves planning, developing, deploying and optimizing an application.
This process manages the design, development and sale of a particular product. Unlike ALM, PLM often implies the manufacturing of a physical product in addition to software. PLM also gives greater focus to the packaging, marketing and sales of a product with the goal of speeding time to market.
