Top 5 Software Development Methodologies

top-5-software-development-methodologies

A software development is the process of dividing software development work into distinct phases to improve design, product management, and project management. It is also known as a software development life cycle (SDLC). Top 5 Software Development Methodologies may include the pre-definition of specific deliverables and artefacts that are created and completed by a project team to develop or maintain an application.

According to a study, it is found that the number of Software Development Companies in USA is largest, but India holds maximum number of talented software engineers. Most modern development processes can be vaguely described as agile. Other methodologies include waterfall, prototyping, iterative and incremental development, spiral development, rapid application development, and extreme programming.

Software Development Methodologies

  1. Waterfall
  2. V-Shaped
  3. Spiral
  4. Incremental and Iterative
  5. Agile and Scrum

5 Software Development Methodologies in detail:

#1.  Waterfall model:

The waterfall model is a sequential approach, where each fundamental activity of a process represented as a separate phase, arranged in linear order.

When To Use?

In principle, the waterfall model should only be applied when requirements are well understood and unlikely to change radically during development as this model has a relatively rigid structure which makes it relatively hard to accommodate change when the process in underway.

Top 5 Software Development Methodologies

Salient Features-:

  • It is considered as the traditional method of explaining software development process.
  • It is also known as linear sequential life cycle model.
  • In this model the next phase in the development process won’t begin until and unless the previous phase is completed. The phases don’t overlap each other.
  • It is best suitable where requirements are predictable and stable.
  • It is best suitable for small projects.

Advantages and Disadvantages-:

Advantages Disadvantages
  • Ease in understanding.
  • It is a structured approach.
  • Stages and activities are well defined.
  • Helps in proper planning and scheduling of activities.
  • Early detection of errors, as it allows verification at every stage.
  • Poor anticipation of possible outcomes.
  • It’s challenging to go back to any stage    once it’s finished.
  • Limited flexibility.
  • Huge cost of implementation.
  • It doesn’t specify the guidelines of how to handle the change in requirements

#2. V-Shaped model:

An extension of the waterfall model, this SDLC methodology tests at each stage of development. As with waterfall, this process can run into roadblocks.

What it is:

The V-shaped software development process is a take on the classic Waterfall method that makes up for its biggest downfall: A lack of testing.

Who it’s for: Teams working on smaller projects with a tight scope.

Who it’s not for: Teams who want more flexibility and early input from users.

Phases:

  • Requirements
  • Specifications
  • High-level design
  • Low-level design
  • Development
  • Unit testing
  • Integration testing
  • System testing
  • Acceptance testing

Salient Features:

  • It is considered as an extension of Waterfall model.
  • It is also termed as Verification and validation model.
  • Every phase in developmental cycle is supported with testing phase.
  • It is best suitable for projects where technology and requirement is stable. The major difference between v-shaped model and waterfall model is the early test planning in v-shaped model.

Advantages and Disadvantages:

Advantages Disadvantages
  • It is simple and easy to use.
  • Each phase has specific deliverables.
  • Higher chance of success over the waterfall model due to the development of test plans early during the life cycle.
  • It is best suitable for small projects.
  • It is rigid.
  • Formation of prototypes of the software happens at implementation stage.
  • Model doesn’t provide a clear path for problems found during testing phases.
  • Requires updating of test project if any changes happen in mid-way.

#3. Spiral Method:

 

Top 5 Software Development Methodologies

Salient Features:

  • It is a composite of Waterfall Model and Iterative Model.
  • Each phase of the software development process leads to the formation of spiral with many loops.
  • It is favorable for broad, premium and complicated projects.
  • Each phase is marked with and ends with client examining the project.

 Advantages and Disadvantages:

Advantages Disadvantages
  • It involves two way communications between client and developer, so the client feedback is always invited.
  • Formation of prototypes happens at early stage, so cost estimation becomes easy.
  • Changes can be performed at later stage.
  • Requirements can be predicted more accurately.
  • Strict adherence to spiral model protocols.
  • It is not feasible for small projects.
  • Huge documentation is required because of intermediate phases.
  • Requires appropriate risk assessment.

#4. Iterative and incremental Model:

They’re suited for large projects, less expensive to the change of requirements as they support customer interactions with each increment.
Initial versions of the software are produced early, which facilitates customer evaluation and feedback.

What it is:

The incremental and iterative software development processes are a middle-ground between the structure and upfront planning of the Waterfall process and the flexibility of Agile. While both follow the idea of creating small bits of software and exposing them to users for feedback, they differ in what you create during each release.

Salient Features-:

  • It is developed to overcome the weaknesses of the waterfall model.
  • It starts with an initial planning and ends with deployment with the cyclic interactions in between. The basic idea behind this method is to develop a system through repeated cycles (iterative) and in smaller portions at a time (incremental), allowing software developers to take advantage of what was learned during development of earlier parts or versions of the system.
  • It consists of “mini waterfalls” cycles.
  • It is used in shrink-wrap application and large system which built-in small phases or segments. Also can be used in system has separated components, for example, ERP system. Which we can start with budget module as first iteration and then we can start with inventory module and so forth.

Advantages and Disadvantages

Advantages Disadvantages
  • Generates working model at the early stage of development cycle.
  • Effective utilization of scarce resources through proper increment definition.
  • Can accommodate some change requests between increments·
  • Reduction of initial delivery cost.
  • Involvement of client at each stage.
  • Heavy dependency on pre planning.
  • Follows a defined set of processes.
  • Defines increments based on function and feature dependencies·
  • It is more expensive than waterfall model.
  • Integration between iteration can be an issue if this is not considered during the development.

#5. Extreme Programming (Agile Development):

What it is:

The Spiral software development process combines the V-shaped process’ focus on testing and risk assessment with the incremental nature of Iterative, Incremental, and Agile.

This SDLC model emphasizes repetition. Developers create a version very quickly and for relatively little cost, then test and improve it through rapid and successive versions. One big disadvantage here is that it can eat up resources fast if left unchecked.

Phases:

  • Planning
  • Risk Assessment
  • Development and validation
  • Evaluate results and plan next “loop”

Salient Features-:

  • Its sole mission is to improve customer satisfaction and process adaptability.
  • It can be used with any type of the project, but it needs more involvement from customer and to be interactive.
  • Also, it can be used when the customer needs to have some functional requirement ready in less than three weeks.
  • It is based on adaptive approach.
  • We at Dreamsoft4u work on the same model.

Advantages and Disadvantages

Advantages Disadvantages
  • It is a realistic model of software development.
  • Boost cross training and team work.
  • Best suitable for dynamic environment.
  • Awards flexibility to developers.
  • Requires exclusive skills for the team.
  • Documentation is done at later stage.
  • Reduce the usability of components.
  • Lack of documentation.
