What is the software development process and what does it look like in practice?

The software development process (Software Development Life Cycle) involves a number of stages, from requirements analysis to maintenance of the finished product. The article discusses various methodologies and techniques that help development teams create efficient, reliable and customized solutions. Learn how to effectively manage each stage to achieve high-quality software and accelerate the delivery of new functionality.

The software development process is an end-to-end approach to creating IT systems, covering all stages from conception to implementation and maintenance. According to the State of Agile 2023 report, 94% of organizations now use formalized manufacturing processes, which translates into 23% higher project delivery efficiency compared to ad-hoc companies.

An effective manufacturing process is characterized by precisely defined phases, roles and responsibilities, and metrics for success. Standish Group research indicates that organizations using structured processes achieve a 35% higher rate of successful projects.

Flexibility and the ability to adapt the process to the specifics of the project and the organization are key in the modern approach to software development. McKinsey Digital (2023) highlights that companies capable of rapidly adapting their manufacturing processes achieve, on average, a 28% higher return on investment in software development.

What are the key stages of software development?

The standard software development process consists of several key stages, the proper implementation of which determines project success. According to PMI’s Pulse of the Profession (2023), organizations using clearly defined milestones achieve a 27% higher rate of projects completed on time.

First, business and technical analysis is carried out, which according to Gartner (2023) should consume about 15-20% of the total project budget. This is followed by architecture and detailed solution design, which accounts for another 20-25% of resources.

Implementation and testing are usually the largest part of the process, taking 40-50% of the time and budget. System implementation and stabilization is the last 15-20% of the process, although these proportions can vary depending on the specifics of the project and the methodology adopted.

What does the software life cycle include?

Software Development Life Cycle (SDLC) is a comprehensive model that describes all phases of an IT system’s existence. According to research by IEEE Software (2023), a properly defined SDLC can reduce the time it takes to make changes to a system by up to 40%.

A key element of the SDLC is requirements management, which according to Standish Group accounts for 30% of the factors affecting project success. The process must be continuous and iterative, taking into account changing business and technology needs.

The modern approach to SDLC pays particular attention to aspects of DevOps and continuous integration. The State of DevOps Report 2023 indicates that organizations using advanced DevOps practices achieve 96 times more frequent deployments while reducing bug fix time by 76%.

What is the software development process?

The software development process is a comprehensive approach to developing information systems, covering all stages from conception to implementation and maintenance. It is a structured way of working that allows for efficient management of resources and minimization of project risks.

An effective manufacturing process is characterized by precisely defined phases, roles and responsibilities, and metrics for success. Proper documentation and communication between all parties involved is also critical.

In the modern approach to software development, special attention is paid to the flexibility and adaptability of the process to the specifics of the project and the organization. This allows rapid response to changing business and technological requirements.

What are the key stages of software development?

The standard software development process consists of several key stages, the proper implementation of which determines the success of the project. Each of these stages requires appropriate team and resource commitment.

The first step is always a business and technical analysis, during which the main objectives of the project, functional and non-functional requirements and technical constraints are identified. Close cooperation with business stakeholders is crucial at this stage.

The next phase is the design of the architecture and detailed solutions. This is the moment when key technical decisions affecting the future scalability and maintainability of the system are made. Here, experienced architects lay the foundation for future application development.

What does the software life cycle include?

The Software Development Life Cycle (SDLC) is a comprehensive model that describes all phases of an IT system’s existence – from initial conception, through implementation, to decommissioning. According to the “State of DevOps 2023” report by Google Cloud, organizations that follow mature DevOps practices achieve significantly better results in terms of system stability and speed of change implementation.

A key element of the SDLC is requirements management, which must be done continuously and iteratively. This allows the project to remain flexible while maintaining consistency and direction.

The modern approach to SDLC pays special attention to aspects of DevOps and continuous integration. These practices allow for faster error detection and more efficient implementation of new functionality.

What does the analysis and planning phase of the project look like?

The analysis and planning phase is the foundation of any IT project. At this stage, the project team focuses on understanding the client’s business needs and determining how to meet them. The involvement of all stakeholders – from business representatives to the technical team – is key here.

During the analysis, special attention is paid to identifying business processes to be automated or streamlined. The analysis team creates process maps, documents use cases and defines key business scenarios. A practical tool here is workshops with end-users, during which detailed information is collected about the way they work and what they expect from the system.

Project planning includes creating a schedule, defining milestones and defining the team structure. A risk management plan is also created at this stage, taking into account potential technical and organizational risks.

How are the requirements for new software determined?

The process of defining requirements is a key element in determining the success of a project. Requirements are divided into functional, describing what the system is supposed to do, and non-functional, specifying how the system is supposed to work in terms of performance, security or scalability.

Effective requirements gathering requires a variety of techniques. Stakeholder interviews are fundamental, but equally important is the analysis of existing documentation, observation of business processes or prototyping. A good practice is to use the “user story mapping” technique, which allows visualization of functionality from the user’s perspective.

Each requirement should be described according to the SMART principle – it is to be specific, measurable, achievable, relevant and time-bound. This helps in later verification that the system actually meets the customer’s expectations.

How does the system design stage proceed?

System design is the process of translating business requirements into specific technical solutions. At this stage, architects and designers create a detailed system architecture, taking into account both functional and non-functional aspects.

The key element is to choose the right application architecture. It can be a monolithic, microservices or serverless-based architecture – the choice depends on the specifics of the project, performance requirements and development plans. According to the CNCF’s “Cloud Native Survey 2023” report, microservices architecture is currently the dominant choice in new enterprise projects.

Designers also focus on creating the data model, defining APIs and designing the user interface. All of these elements must work together to create a cohesive and effective solution.

What is the software implementation phase?

Implementation is the stage where concepts and designs are transformed into working code. This process requires close collaboration between developers, architects and business analysts to ensure that the solution being developed is consistent with the design intent. The development team works according to established coding standards to ensure code consistency and maintainability.

A key element of the implementation phase is proper source code management. Teams use version control systems, most commonly Git, to track changes and enable effective collaboration among multiple developers. The code review process is standard practice, allowing for early detection of potential problems and knowledge sharing within the team.

Implementation usually proceeds in iterations, where each iteration delivers a specific business value. This approach makes it possible to quickly receive feedback from users and make necessary adjustments. The practice of continuous integration ensures that new code is regularly integrated into the main branch of the project and automatically tested.

What is the process of testing new software?

Testing is a multi-stage process of verifying the quality of software being developed. It starts at the level of writing code through unit tests and ends with comprehensive acceptance testing with the customer. An effective testing strategy combines different types of testing to ensure full coverage of system functionality.

Unit tests, written by developers, verify the correctness of individual components. Integration tests verify cooperation between different parts of the system. At a higher level, system and end-to-end tests are conducted, which verify the operation of the entire application. Performance and security tests play a special role and should be conducted regularly during system development.

Test automation is a key component of the modern manufacturing process. It allows to quickly detect regressions and ensure system stability. Automated tests are an integral part of the CI/CD pipeline, providing immediate feedback on the quality of changes being made.

What are the most important aspects of implementing the system?

System implementation is a critical moment in the software life cycle, requiring careful planning and coordination. The process involves not only the technical aspects of getting the system up and running, but also preparing users and the organization for change. It is crucial to develop a detailed implementation plan that takes into account various scenarios and potential problems.

An important element is the preparation of the production environment, which must meet all performance and security requirements. The implementation process should be automated as much as possible, which minimizes the risk of human error. Equally important is the preparation of a contingency plan (rollback plan), allowing a quick restoration of the previous version of the system in case of problems.

User training and documentation preparation are an integral part of the implementation process. Users must be properly prepared to work with the new system, and the support team should be ready to respond to potential problems. A phased approach is often used, where the system is implemented gradually in different parts of the organization.

What are the differences between popular software development methodologies?

There are various methodologies in the world of software development, each with its own unique characteristics and applications. The basic division includes traditional (cascading) and agile (agile) methodologies. The choice of the appropriate methodology depends on the specifics of the project, customer requirements and the maturity of the organization.

The cascade methodology is characterized by a sequential progression through the phases of a project. Each phase must be completed before the next one begins, ensuring accurate planning and documentation. This type of approach works especially well for projects with clearly defined, unchanging requirements, such as banking or medical systems.

In contrast, agile methodologies, such as Scrum or Kanban, are based on iterative and incremental value delivery. They allow rapid response to changes in requirements and regular delivery of working software. This approach is particularly effective in a dynamic business environment, where requirements can change frequently.

What are the advantages and disadvantages of the cascade methodology?

The cascade methodology, although often criticized for its rigidity, is still applicable to certain types of projects. Its main advantage is process transparency and accurate planning. It works well in projects where security and documentation are a priority, such as business-critical systems.

One of the key advantages of this approach is the precise definition of scope and budget at the beginning of the project. This facilitates resource management and long-term planning. In addition, the extensive documentation produced during the project provides a valuable resource for future maintenance teams.

However, the cascade methodology also has its limitations. The biggest challenge is the difficulty of responding to changes in requirements during the project. In addition, the client sees the results of the work only at the end of the manufacturing process, which can lead to discrepancies between expectations and the delivered solution.

Why use agile software development methodologies?

Agile software development methodologies respond to today’s IT market challenges. Their primary advantage is the ability to respond quickly to changing business requirements. Thanks to the iterative approach, the team regularly delivers working fragments of the system, which allows early detection of potential problems and adjustment of the product’s development direction.

The agile approach places special emphasis on communication within the team and with the customer. Daily standup meetings, regular sprint reviews and retrospectives allow for ongoing monitoring of progress and continuous improvement of the manufacturing process. This transparency builds trust between all project stakeholders.

An important aspect of agile methodologies is also the emphasis on technical quality. Practices such as continuous integration, pair programming and regular code reviews are built into the manufacturing process. This ensures that the resulting software is not only functional, but also easy to maintain and develop.

How does the Scrum methodology work in practice?

Scrum is one of the most popular agile methodologies, offering clearly defined roles, events and artifacts. At the center of the methodology is the scrum team, consisting of the Product Owner, Scrum Master and development team. Each of these roles has precisely defined responsibilities, ensuring effective project execution.

Work in Scrum is organized in sprints – usually two- or three-week periods during which the team completes planned tasks. Sprints begin with planning, where the team, together with the Product Owner, selects tasks from the product backlog and sets the sprint goal. Daily meetings (daily scrum) allow the team to synchronize activities and react quickly to obstacles that arise.

A key element of Scrum is the sprint review, during which the team presents the completed functionality to stakeholders. This meeting provides valuable feedback and allows the team to adjust the direction of the product. The sprint ends with a retrospective, where the team analyzes its way of working and identifies areas for improvement.

How do you ensure the quality of the software you develop?

Ensuring software quality is a process that must be built into the entire manufacturing cycle. It begins at the planning stage by properly defining acceptance criteria for specific functionality. The development team uses practices such as coding standards, code reviews and pair programming to help maintain technical quality.

Test automation is a fundamental part of the quality assurance process. Unit, integration and end-to-end tests are performed automatically with every change in the code. In addition, regular performance and security tests help detect potential problems before they occur in the production environment.

Managing technical debt is also an important aspect. The team must regularly spend time refactoring the code and updating the technologies used. This helps keep the code in a condition for effective development and minimizes the risk of technical problems in the future.

What are the most common challenges in the software development process?

The software development process involves many challenges, both technical and organizational. One of the key ones is managing changes in requirements. Even in agile methodologies, frequent changes can affect a project’s schedule and budget. It is crucial to develop a process that allows flexible response to changes while maintaining project stability.

Communication among team members and with stakeholders is another significant challenge. For dispersed or international teams, time and cultural differences can further complicate collaboration. Regular meetings, clear documentation and the use of appropriate communication tools help overcome these difficulties.

Managing technical debt requires striking a balance between the speed of delivering new functionality and maintaining high technical quality. The team must make informed decisions about refactoring and code modernization, taking into account both short- and long-term consequences.

How to effectively manage changes during software development?

Change management is one of the key elements of the software development process. Every change, whether in business requirements or technology, must be properly evaluated and planned. Effective change management requires the development of a transparent change process that balances flexibility with project stability.

In practice, the change management process begins with proper change analysis. Each change proposal should go through an assessment of the impact on the system, schedule and budget of the project. The technical team analyzes the impact of the change on the system architecture and existing code, while the Project Manager assesses the impact on time and resources. The Product Owner, on the other hand, verifies the business value of the proposed change.

Communication of changes to all stakeholders is also an important aspect. Any approved change must be properly documented and communicated to the team. For significant changes, it is a good idea to hold dedicated planning sessions where the team can discuss together the best approach to implementation.

How do you measure the progress of software development?

Measuring progress in IT projects requires a comprehensive approach that combines various metrics and indicators. The primary metric in agile methodologies is team velocity (velocity), which shows how much work a team is able to complete in a single sprint. However, velocity alone does not give a complete picture of progress – it needs to be supplemented with qualitative metrics.

It is critical to monitor code quality through automated metrics such as test coverage or the number of bugs detected by static code analysis tools. Equally important is tracking the time spent fixing bugs and resolving technical debt. These metrics help assess whether the team is striking the right balance between delivering new functionality and maintaining high technical quality.

A burndown chart that visualizes the remaining work in relation to time is also a valuable tool. This allows you to quickly identify potential delays and take appropriate corrective action. For larger projects, it is also useful to track the achievement of milestones and key business objectives.

What does it look like to work with a client when developing dedicated software?

Effective cooperation with the client is the foundation of a successful IT project. It is crucial to establish regular communication channels and a clear decision-making process. In agile methodologies, the role of intermediary between the team and the customer is played by the Product Owner, who is responsible for prioritizing requirements and ensuring that the resulting solution delivers the expected business value.

Regular progress presentations, usually in the form of sprint reviews, allow the client to keep the system development up-to-date and provide feedback. It is important that these meetings are well prepared and focus on the business value of the functionality being delivered. Demonstrations should be conducted in the context of business goals, not just the technical aspects of the implementation.

For more complex projects, it’s also a good idea to hold strategy workshops with the client to discuss long-term goals and directions for the system. Such meetings help the team better understand the business context and make better technical decisions.

What determines the success of an IT project?

The success of an IT project depends on many interrelated factors. Of fundamental importance is a proper understanding of the client’s business needs and translating them into a technical solution. Equally important is building a competent and motivated team that can effectively collaborate and adapt to changing requirements.

Proper project risk management also plays a key role. This requires regular identification of potential risks and preparation of plans to mitigate them. Special attention should be paid to technical risks, such as integrations with external systems or scalability of the solution, and organizational risks, such as availability of key team members or changes in business priorities.

An organizational culture that supports continuous improvement and open communication is also important. Teams that regularly analyze their way of working and actively look for areas for improvement are more likely to deliver a valuable solution. It is also important to foster an atmosphere of trust and cooperation, both within the team and in the relationship with the client.

What are the key roles in a software development team?

The success of an IT project largely depends on the proper distribution of roles and responsibilities within the team. Each role requires specific competencies and experience, and their proper interaction creates an effective project team.

The Product Owner plays a key role in determining the direction of product development. He is responsible for maximizing the business value of the delivered solution. The Product Owner works closely with business stakeholders, gathers and prioritizes requirements, and ensures that the team understands the business context of the functionalities being implemented.

The Scrum Master or Project Manager is responsible for the smooth functioning of the manufacturing process. His job is to remove obstacles, facilitate team meetings and ensure continuous improvement of the process. In the case of more traditional methodologies, the Project Manager is additionally responsible for planning and controlling project execution.

Architects and Tech Leads define the technical foundation of the solution. Their role is to design the system architecture, make key technology decisions and ensure the technical integrity of the solution. In addition, they support the team in solving complex technical problems.

Developers are the core of the manufacturing team. They are responsible for implementing functionality according to requirements and technical standards. Today’s developer must combine programming skills with an understanding of business processes and the ability to work as a team.

The QA (Quality Assurance) team ensures the quality of the delivered solution. Testers work with developers from the beginning of the manufacturing process, helping to define acceptance criteria and design tests. Their role goes beyond just testing – they are the guardians of the quality of the entire manufacturing process.

DevOps Engineers take care of infrastructure and process automation. Their work includes configuring environments, automating deployments and monitoring the running system. In modern teams, the line between DevOps and development roles is often blurred, following the “You build it, you run it” philosophy.

What is the organization of work in large software development teams?

Managing large software development teams requires a special approach to work organization. For projects involving dozens of people, it becomes crucial to properly divide the team into smaller, autonomous units.

A popular approach is based on the concept of feature teams, where each team is responsible for a specific functional area of the system. This division minimizes dependencies between teams and speeds up the manufacturing process. Each team has a set of competencies necessary to deliver business value independently.

Coordination between teams requires appropriate structures and processes. Practices such as Scrum of Scrums or regular coordination meetings allow work to be synchronized and problems to be solved at the interface between teams. Common manufacturing standards and practices also play an important role, ensuring technical consistency across the solution.

Knowledge management in large teams is a separate challenge. It is necessary to create effective knowledge-sharing mechanisms, such as internal training, technical documentation or knowledge-sharing platforms. It is also important to build an organizational culture that supports knowledge sharing and mutual learning.

The aspect of communication in large teams requires special attention. A balance must be struck between ensuring that everyone has access to the necessary information and avoiding being overwhelmed by excessive communication. Knowledge and communication management tools are helpful here, as are clearly defined processes for making and communicating decisions.
