Software Development Life Cycle
                     SDLC
SOFTWARE DEVELOPMENT LIFE CYCLE
What is SDLC Process?
The process defines different phases that are needed to deliver an application.
Planning Stage Analysis Stage Design Stage
The phase in which Gather all the specific Outline overall 
developers will details required for a application details, 
plan for the new system & alongside UI, 
upcoming project. prototype ideas Database, coding, etc.
Development Stage Testing Stage Integration Stage
Write code and Track bugs or Different modules & 
build the defects. Fixed designs will be 
application as per them, and later integrated into the 
design and outline. retested. primary source code
LAUNCH
Purpose
 Lead to good software
 Reduce risk
 Enable visibility and measurement
 Enable teaming
KEY ELEMENTS IN ANY SDLC

 Development
 Validation
 Evolution/Maintenance
SDLC Models
 Waterfall Model
 Iterative Model
 Evolutionary Model
 Prototype Model
 Spiral Model
 RAD Model
 Agile Model
 Incremental Model
1 Planning Stage
Requirements Analysis
 Requirements Analysis must be done before any 
custom software development work can begin. It is a vital part of 
the software life cycle process where requirements are gathered 
and analyzed by the business people who are responsible for 
implementing the application. 
 They will identify what they need from an application to do their 
jobs quicker, better and cheaper. Once the requirements have 
been identified, it is then possible to gather together the 
resources such as developers, testers, analysts and designers 
who will create the software. 
 By doing so, it gives them a clearer picture of how things should 
be implemented in order to achieve these objectives. This 
ensures a smoother and faster implementation of the customized 
and agile software development solution.
Planning
 In order to meet the quality standards, planning for the project is 
done in the early stages itself. Once the study of the market 
research is completed, we come up with recommendations 
regarding the feasibility of the product. Also, the feasibility study 
helps us to identify potential areas where we may face problems 
during implementation. We then go ahead and plan accordingly.
2 Analysis Stage
Defining Requirements
 Once the requirement analysis has been completed, the second 
step would be to clearly define and document these 
requirements, and ask those who approve the requirements if 
they are OK with them.
 This process is achieved through an SRS(Software Requirement 
Specification) or RFP (Request For Proposal). The RFP contains all 
the product requirements needed to be implemented during the 
project life cycle along with a detailed description as to how they 
should be met.
3 Design Stage
Designing the Product 
Architecture
 SRS is the key resource for product architects to work out how 
the product should be developed. Based on what's needed, the 
technical people develop a specification document outlining the 
product's features and functionality. From this document, they 
can propose multiple approaches to building the product. They 
present these ideas to the business people who then decide on 
what direction to take.
 This DDS is evaluated against a number of critical parameters 
before being recommended to the client. Based on these various 
factors, an appropriate design solution can be identified and 
incorporated into the project plan.
 A design approach clearly defines all of the product's 
architectural modules, as well as its communication and data 
flow representation with external and third-party modules (if 
any). The internal design of all modules of the proposed 
architecture should be clearly defined in DDS down to the 
smallest detail.
4 Development Stage
Building or Developing the 
Product
 During this stage of SDLC, the actual development starts, the 
Product is designed, the coding code is generated according to 
DDS, and then the project is rolled out on an iterative basis based 
on feedback gathered from users and stakeholders. We should 
expect issues to arise throughout the development cycle, so we 
should have a plan ready for each one. 
 These plans should be documented and communicated clearly to 
everyone who is involved in the process. Once the problem has 
been resolved, the next step is to roll back to the last working 
version of the code, and repeat the same steps until the desired 
functionality has been implemented.
 Developers should follow the standards set out by their 
organization and any development tool used. Compilers, 
interpreters, debugging tools, and so forth are used to create the 
source code. 
 A wide variety of programming languages can be used including 
C, Objective-C, C, Java, COBOL, BASIC, HTML, XML, XSLT, CSS, 
Perl, Python, PHP, Ruby, JavaScript, etc. The choice of 
programming language is dependent upon the type of application 
being made.
5 Testing Stage
Testing the Product
 This stage is usually included in all the processes of the SDLC 
model. The testing activities involve all of the stages of the SDLC 
model (Requirements Analysis, Design, Implementation, Testing, 
Maintenance).
 However, this stage is referred to as the testing phase of the 
product, where defects are reported, tracked and fixed, until the 
product meets the quality standards set out in the SRS.
6 Integration Stage
Deployment in the Market
 Once the product has been thoroughly tested and is ready for 
deployment, it is formally released in the relevant market. 
Product deployment may occur in stages depending on the 
organization's business plan. The product may first be introduced 
in a small market sector and tested in a real-world business 
setting.
 The product may then be released as is or with proposed 
enhancements in the targeted market niche depending on the 
feedback. Following the product's release to the market, it is 
maintained for the current client base.
