Software Product Development Life Cycle—Full Guide For 2022

Software Product Development Life Cycle—Full Guide For 2022 | OmiSoft

Curious about the software product development life cycle? Then look no further as we got everything you should know about the life cycle of software. Let’s start with some basics.

What’s a product development life cycle? SDLS—is a period of time that begins with the decision to create a software product and ends with the moment of its complete withdrawal from service.  Simply put:

The concept develops into a marketable product 

As a rule, SDLS has 4 main stages:

  1. Entry stage
  2. Growth stage
  3. Maturity stage
  4. Decline stage

However, there are different types of the software life cycle that facilitate the design, development, and release of a high-quality software product.

But how to choose among all of the options? Let’s explore the main methodologies used in the product development process.

#1 Waterfall model (aka cascade)

In this model, each phase of the project is carried out once, in order. To start the next stage, you must finish the previous one.

Pros Cons
  • A clear sequence of all project stages
  • Hard to make clear requirements
  • Easy to plan the deadlines and resources needed
  • No way to change requirements
  • No change of requirements throughout the cycle
  • Users can’t check the product’s quality until the development process is complete

#2 V-model

This model can help to eliminate the shortcomings of the cascade model, which was used before. This model makes it possible to test processes at all stages so that transitions between levels can occur smoothly.

Pros Cons
  • No room for wiggle—strict phasing
  • Hard to adapt if client’s requirements change
  • Risks minimization with early testing
  • Development takes a long time
  • Improved time management
  • No risks analysis

#3 Incremental model

The incremental model of software development is based on a linear sequence of stages, with each stage being divided into several increments (versions). This way of planning software development is more flexible than the cascade method.

Like other software development models, the incremental model is composed of several stages. However, unlike other models, the increments (versions) are created all along the way. This allows you to see product improvements and fixes as they are being made.

Pros Cons
  • Client’s feedback is possible for each version of the product
  • To give iterations functions must be fully defined at the start
  • Cost and time risks review is possible
  • Constant changes might break the system’s structure
  • Gradual implementation of the new technology, so the client doesn’t have a “change shock”
  • Delivery deadlines might extend if the resources are limited (developers, finances)

#4 Spiral model

In the spiral model, the life cycle of a product under development unwinds in the shape of a spiral, beginning at the planning stage. Each step of development brings us closer to a tested prototype that meets all requirements. After many iterations, we have a finished product that meets all our requirements.

Pros Cons
  • Special risk management
  • Assessment of risks is not cheap
  • No probs to add extra features later on
  • Constant client feedback may lead to constant iterations and therefore delay in product development
  • Possibility of flexible design
  • Works better for large projects and is less effective for small ones

#5 Agile model

Agile development is a pack of different methods of software development, some of which involve iterative development (e.g, Scrum). Each iteration, or sprint in the product development life cycle Agile, is considered to be a miniature software project. One of Agile’s main ideas is collaboration within the team and directly with customers.

Pros Cons
  • No decision-making block thanks to constant communications
  • Product development increases with a large number of meetings and discussions
  • Minimization of risks
  • Harder to plan with constantly changing requirements
  • Fewer documentation headaches
  • Rare for large projects

OMIBONUS: Scrum

Scrum is a software development methodology that provides a framework for teams to manage their projects. Clear roles (Scrum Master, Product Owner, Team) allow for a simple distribution of responsibilities in the development process. 

  • The Scrum Master is accountable for the success of the methodology in the project and is the tying component between the team and management. 
  • The Product Owner sets tasks and makes final decisions for the team; they also develop products that customers want. 

The team works together in short time periods called sprints. At the end of every Sprint, the team shows results of it.

Pros Cons
  • Fast expert feedback
  • Some people can become indispensable, as documentation isn’t provided during the development process
  • Testers are involved in the work, so the product can be launched with min functions
  • You can’t plan ahead, as everything depends on the completion of the previous sprint
  • Team is fully independent and self-organized
  • Hard to get for not devs. To understand clients need to do some good “reading”

As you can see, you’ve got many options for software development models. The choice depends on the specifics and requirements of the particular project and the payment system you like to use. You may notice that some methodologies overlap and are alike, but still, each is loved by some developers and clients.

Conclusion 

Depending on the size of the product and the detailed study of the technical task, you can choose the most suitable methodology. If you feel like you are not in control of the product development life cycle management, you may need to review the chosen development methodology.
