Application Lifecycle Management (ALM)

Application development from start to finish

Application Lifecycle Management (ALM) is the monitoring of an application over its entire life cycle. In the course of digitization, the topic of ALM is becoming more and more important for companies. Business processes, business models and products are constantly changing. As a result, IT departments within companies must adapt their systems ever faster and establish new ones. 

ALM is intended to increase the overall quality of the software. Standardization of the individual steps ensures greater efficiency and better cooperation between the development team and users. The overall process is divided into different phases, which are explained in more detail below 

The ALM Phase Model

ALM handles and inter meshes application development (requirements, design, and development) and application operation (roll-out, operation and optimization) equally. The phase model ensures that the individual steps of implementation are observed and continuously checked. The individual areas are described in more detail below. 

1. Requirement Phase

The initial phase of Application Lifecycle Management includes a requirements analysis. This includes the determination and analysis of requirements. The basic orientation of the application is usually oriented to the strategic planning of the company. For this reason, it is particularly important in the first phase to understand as concretely as possible what the company wants to achieve with the application. In addition, it should be determined which components the application should have in any case and which can be added later. 

The result of this phase is a specification sheet clearly defining the contents and implementation guidelines. In addition, the first mock-ups and design drafts can be made. 

FROM OUR BLOG: #1 In the beginning was the idea…
The 1st phase of software development begins with the requirement analysis. First, project managers and stakeholders define the various requirements and check their feasibility. Read more »

2. Conception phase

In the conception phase, the requirements from the first phase are translated into functionalities and the required architecture is defined. The focus is on the selection of suitable solutions. During this phase, it can always come back to the requirements phase if details have not been worked out well enough. 

The result of the conception phase is a rough and a detailed concept. Concepts for design, software architecture, release management and test management can be added. 

FROM OUR BLOG: #2 App Design Planning
The 2nd phase of software development is dedicated to design and planning. This is where the first mock-ups are created according to the previously defined requirements and the architecture of the application is prepared. Read more »

3. Development Phase 

The development phase includes the implementation of the application and architecture. Important milestones of this phase are setting up the development and acceptance environments, developing the software, documentation and installing the solutions in the integration environment. 

The results of this phase are various manuals for installation, administration and operation as well as demand oriented test scenarios and unit tests carried out by the developer. 

FROM OUR BLOG: #3 App implementation
In the 3rd phase of software development the implementation takes place. With the prototypes already well advanced, much of the work is already taken over in the design phase. Read more »

4. Quality Assurance Phase

The quality assurance phase starts with the completion of the actual software development and programming work and the start of the acceptance process. The developer tests the software in a development or integration environment. Furthermore, all created documents and test scenarios are checked again. If errors are found during this process, a feedback process takes place. The errors are documented and mirrored back to the implementation team. Rework and inspection phase alternate until no more errors are found in the application. 

Once the development team has given the green light, acceptance can be given to the company or the user. If no more defects are discovered here either, the quality assurance phase is regarded as completed. 

The results of this phase are an internally and externally tested application and an acceptance protocol. 

Now that the app has been developed, the 4th phase of software development is ready for testing. Here, the application is put through its paces ad compared with the requirements before it is released to the end users. Read more »

5. Product-Release Phase

In the product release phase, the roll-out and go-live takes place. In addition, there is versioning, which must ensure that every version remains maintainable by the user or company and that bug-fixes can also be carried out in the future. 

In addition, all users should be familiarized with the software during this phase and, if necessary, training courses should be held. 

FROM OUR BLOG: #5 App Release
Once all errors have been detected and the app is reliable, it is time for the 5th phase of software development in which the app is published and made available to the end users. Read more »

6. Maintenance and Optimization Phase

The maintenance and optimization phase usually takes place in the background without the user noticing. While the application is already in use, it is maintained by a support team in order to quickly correct any errors that may occur. 

FROM OUR BLOG: #6 App Maintenance
In the 6th phase of software development, a company must take care of the maintenance of its app. Read more »
