A software development process can be divided into several stages. First of all, it is planned, and then created; the next steps involve analyzing the results, correcting them, if necessary; then the product is made available to its users who begin to exploit it, and marketing department staff analyze user demand.
When the product will occupy the place in a given market, so to say its market niche, the developers think how to improve it, make changes to its architecture and design, etc. There can be dozens of new software versions released and the product finally become obsolete and will be replaced by a fundamentally new product. All this is an uneasy product life path, which starts with the very first idea of the software development process, which comes to the authors’ minds and ends with shipping the products’ to their customers, is called a life cycle.

The product life cycle includes many stages. Usually, most information sources describe these as sequential interdependent processes, as if they followed one after the other in order, – but, in fact, they do significantly overlap.
Here Are Five Main Phases of The Software Life Cycle:
- Planning
- Design
- Coding and documentation development
- Testing and bug fixing
- Maintenance (after the release) and modification
When using independent software testing services, you can be sure that your products will be thoroughly verified and you will have clear idea of their quality. At that, your expenses will be lower than that of in-house specialists.
The book “Software Maintenance” contains information on relative cost of each phase. Here are the figures:
Development Phases Stage of the Process
Requirements Analysis 3% Industrial production and maintenance 67%
Specification 3%
Design 5%
Coding 7%
Testing 15%
All these figures were firstly published in 1979. According to the experts, maintenance of post-release software is the most expensive of the phases. A little bit less expensive is a testing phase – 45% of the total cost of the development process is spent on the validation & verification. In the maintenance phase, a significant portion of the costs is also spent on testing while fixing bugs and making improvements to the software. Again, in the development process, the personnel of a penetration testing company are hired to identify and eliminate security breaches. This service helps to protect sensitive data from cyber attacks.
