Top Software Development Methodologies

Top-SDLC-Methodologies-Differences-and-Comparison

Software development is not a task but a process that begins with communication between the client and the vendor and ends at support and maintenance. The entire software development cycle involves the use of one development methodology that decides end to end process of the software development. Process, such as structuring, planning, controlling, timelines, cumulative cost etc. There are many methodologies in the market but only a few have made their place successfully. Software development methodologies have been in the existence for a long time varying from old to new. This is how a software development process works:

It is rightly said that if the company uses an apt methodology then their software development process becomes faster and efficient. According to a survey conducted by Goodfirms, here is the list of top software methodologies.

software methodologies

As the graph shows people chose Agile the most, then Scrum and Waterfall, even if it’s too primitive. Other software development life cycle methodologies can be Kanban, Lean development and Extreme Programming.

Let’s discuss in detail:

Agile

Agile methodology garners for 61.5% in the survey conducted. This means maximum developers and dedicated development teams opt for Agile method. To explain better you need to know about Agile method first. It involves discovering requirements and developing solutions through the collaborative effort of all the teams from development to testing and beyond. Today Agile method is important for development teams be it .Net, java, Python or related to any other language or platform.

Here’s how an Agile module works:

Scrum

Scrum is an Agile framework, therefore the working in Scrum is similar as in Agile with a bit more stricter rules. Scrum helps the teams in working together by learning through experiences and continuously improving.

Waterfall

Waterfall model in software development life cycle is quite a primitive method but it is still practiced by 9.6% of the people surveyed. This means that it still has value. This methodology is linear or stepwise divided in stages and every stage has its own deliverables.

Comparing The 3 Main Methods In Tabular Form

AspectAgileScrumWaterfall
Working modelSprint basedSprint basedLinear or stepwise model
Development teamsWork collaborativelyWork collaborativelyPhase wise involvement
Project headProject head is main in carrying out the entire projectNo one team leader is responsible. Entire team addresses the issuesEvery phase has a separate team leader/head who takes care of that particular deliverable
Design and executionSimple design is recommendedDesign can be innovating and experimentalDesign is decided at the beginning of the project. No changes can be done in between
When to applyFor any-sized projectsLong-term, complex projectsFor fixed-size projects; enterprise software with clear requirements
Client’s interventionClient provides requirements & feedbackClient is main who defines the requirements, provides feedbackHigh during the discovery stage; lower in the next phases
Product deliveryContinuous delivery of the working productProduct delivery after completion of each sprintProduct delivery after final completion of the entire project
SpeedEfficient and fasterEfficient and fasterTraditional and may delay
AdvantagesOpen communication and flexible modelOpen communication and very flexibleSimple, analytical and easy to set budgets
Disadvantages No final price declaration before project begins.
Requires careful management
Requires regular client involvement
Teams lacking self-discipline often fail at it
Final product may vary from client’s expectations
Not at all flexible
