page main image

Custom software development and design is the main activity of the enterprise. The main purpose of software development is to produce a software product that meets the functional and technical specifications of the customer, is quality-tested and flexible for future changes and maintenance. 

In this post, our goal is to familiarise you with different approaches to the software development process to help you understand the specifics of collaboration with IT vendors in each case.

Software Development Process

PNN Soft has 20 years of experience in software development for desktop, web and mobile solutions. Thanks to the old one, the company has a well-established process of realization of technical tasks. The success of a software development project largely depends on the correct methodology choice for its development and management. Depending on the project specifics, we use flexible software development methodologies and practices based on Agile, DevOps, CI, and other. Our specialists use effective and advanced methodologies, including: Scrum, RUP, CI and others.

What is a model in software engineering?

By types of software development models, here, we mean different development methodologies, which implies a structural understanding of the process and the sequence of actions the team needs to perform. In addition, selecting a particular development approach inevitably impacts testing – it specifies what testing technique will be used. 

If stakeholders do not have a plan for cooperation in mind, it frequently results in delays, differences in expectations and arising misunderstandings between businesses and engineering teams. Your first step implies understanding software development lifecycle phases (things should be done regardless of chosen collaboration model). Secondly, the aim is to decide a particular development methodology in line with your company’s needs. So let us consider the first topic in more detail. 

Main phases of the SDLC and their specifics

Depending on the size of employees/vendors, goals and the complexity of the project, some of them may run in tandem, complementing each other and being slightly modified. However, generally, the following stages are mandatory:

Project development models:finding a perfect fit

For whom may suit: large enterprises or governmental agencies, which prefer to sign documents on the project plan before proceeding with development.

For whom may suit: companies who want to test theories or deliver prompt updates to their customers.

For whom may suit: for teams who have precise requirements and expectations but still want to have more flexibility than Waterfall allows. 

For whom may suit: for businesses with a small project requiring a relatively tight scope.
