Exceptional projects start with an exceptional vision. Like any other multifaceted system, software development requires extensive planning, preliminary work, and management, especially if you have to manage multiple processes. Let's see what are the most important points to take into consideration.
For the project to go smoothly, a rigorous system is needed that makes the entire engineering effort effective and allows the software development team to achieve excellent results in a timely manner. The software development cycle (SDLC) is critical in this context.
The SDLC, with its structured methodology, makes it possible to identify and correct development errors right from their inception, minimizing the risk of delays and additional costs. Through careful planning and efficient resource management, the SDLC provides a clear roadmap for project success.
Therefore, a competent software development company should have a solid understanding of the different SDLC models and select the one that best suits the project context and business needs to maximize the efficiency and quality of the software product.
As already outlined, the software development cycle represents the process that a software project follows and includes a detailed plan that describes how to develop, maintain, replace, modify or improve specific software. This life cycle defines a methodology for improving the quality of the software and the entire development process. This approach is widely adopted by software development companies to ensure efficient project management and obtain successful production results.
But what does SDLC imply in software practice? Basically, it's about implementing best business practices for creating technological solutions. As a result, teams are able to produce high-quality software that meets or exceeds customer expectations. The software development cycle also allows companies to perform a detailed analysis of each phase, increasing efficiency and minimizing costs during the entire software development process.
There are usually six phases of software development: analysis, planning, architecture design, development, testing and maintenance. Some Project Managers may decide to combine, divide, or skip certain phases depending on specific project requirements. However, these phases are considered essential components for all software engineering projects.
The software development cycle is a fundamental concept in IT projects. Project managers use SDLCs to define the different phases of development and ensure that they are completed in a timely manner and in the correct order. This methodology is essential to ensure efficient delivery of software systems, while minimizing the presence of defects.
In addition, the software development lifecycle can also be exploited by system analysts during the design and implementation of new information systems.
As already mentioned, the number of phases of software development may vary depending on the methodology applied and the preferences of the development team or company. Consequently, the Agile development process embraces constant variation through an iterative workflow, and each iteration takes into account the next piece of the engineering puzzle. Usually, an iteration lasts from one to four weeks depending on the team and the time of completion. Therefore, the purpose of each iteration is determined by the duration assigned, resulting in a different set of phases for each software product.
On the contrary, the Waterfall methodology is a linear and documentation-rich project management process, with terminal phases. This implies that each phase must be completed before the next one can begin, and there is no overlap between the phases. The Waterfall methodology is usually divided into seven steps, which require careful planning using a Gantt chart. The only way to resume a phase is to start over from phase one.
During this phase of the software development lifecycle, specialists meticulously collect precise requirements from the customer to present a solution tailored to their needs.
Any ambiguities need to be clarified only at this stage. The analysis phase also collects business requirements and identifies any potential risks. This step in the SDLC also includes a feasibility study, which defines all the strengths and weaknesses of the project to assess the overall viability of the project.
The objectives achieved in this phase are identified as the system of functions that your company needs or wishes to develop and implement.
For this, software developers complete three main tasks:
The analysis phase includes:
In this way, you can define the main requirements, which tools and approaches to use and how to achieve your business objectives more efficiently.
Then, the analysis phase helps to understand the main business needs and what to do to meet them.
The purpose of the second phase is to outline the scope of the problem and identify solutions. Resources, costs, time and other aspects should be taken into account here. The planning phase of the software development lifecycle is also when the project plan is developed that identifies, prioritizes, and assigns the tasks and resources necessary to build the structure for a project.
With that said, the passage culminates in a detailed project plan.
The third phase involves two additional steps: High Level Design (HLD) and Low Level Design (LLD). The result of the former is the future architecture of a software product, while the LLD step describes how every single feature of the product should work. It is also at this stage that the database specification is developed to decide on the management and storage of data for future treatment, retrieval or evaluation.
Among other things, the development team will reflect on the main components, structure, treatment, and procedures of the system to achieve the stated objective. This design phase lays the foundation for the next step in the life cycle, namely development.
Software development transforms project requirements and prototypes into a tangible solution. Therefore, engineers begin to create the entire system by processing the code using the required technology. During this phase of the software development lifecycle, customers will be able to get a first look at the future product.
And at the end of the construction process, customers will have operational functionality to share with customers.
In the fifth phase, all pieces of code are tested to verify and validate a software product. The testers then perform software lifecycle activities to monitor the system for bugs and defects. This is done to verify the correspondence between the actual and expected behavior of a program.
The testing phase and the initial phases of the SDLC can be performed both with internal software development and with outsourcing, since they require interaction with the end user.
Once the system is implemented, it is possible to make any updates, improvements and changes, implementing new functionality in the operating software. It is crucial to maintain and modernize the system regularly so that it can adapt to future needs.
When the company is faced with the complexity and disorganization of its management processes, this can be the tangible sign that the time has come to seriously consider adopting software. This transition becomes crucial when one realizes that activities must be monitored across different platforms and that the time spent on frequent refresher meetings is excessive.
There are several situations that may suggest the need for more advanced tools:
Although in the past many small businesses have managed their projects using tools such as spreadsheets such as Microsoft Excel, it's important to understand that such solutions often become obsolete as the size of the company grows.
Implementing dedicated software offers the opportunity to access advanced functionality, such as automated report management, real-time data updating, and scalability to meet business growth needs. This transition is not only a step towards greater efficiency, but also a strategic investment for the future of business project management.
