This approach carries less risk than a traditional Waterfall approach but is still far more risky and less efficient than a more Agile approaches.
In Iterative model, iterative process starts with a simple implementation of a small set of the software requirements and iteratively enhances the evolving versions until the complete system is implemented and ready to be deployed.

The term "Software Development Life Cycle" (SDLC) refers to a methodology for producing high-quality software that includes well-defined processes. The phases of software development that the SDLC approach focuses on in depth are as follows:
Comparing Various SDLC Models On The Basis Of Available MethodologyIJMER
There are various SDLC models widely accepted and employed for developing software.
SDLC models give a theoretical guide line regarding development of the software. Employing proper
SDLC allows the managers to regulate whole development strategy of the software. Each SDLC has its
advantages and disadvantages making it suitable for use under specific condition and constraints for
specified type of software only. We need to understand which SDLC would generate most successful
result when employed for software development. For this we need some method to compare SDLC
models. Various methods have been suggested which allows comparing SDLC models. Comparing SLDC
models is a complex task as there is no mathematical theorem or physical device available. The essence
of this paper is to analyse some methodologies that could result in successful comparison of the SDLC
models. For this we have studied various available tools, techniques and methodologies and have tried
to extract most simple, easy and highly understandable method for comparing SDLC models.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

2. INTRODUCTION TO SDLC
SDLC Stands for Software Development Life Cycle.
The software development life cycle (SDLC) is
a framework defining tasks performed at each step in
the software development process.
It consists of a detailed plan describing how
to develop, maintain and replace specific software.
3. OBJECTIVE OF SDLC
SDLC has Three primary objectives:
Ensure the delivery of high quality systems.
Provide strong management control.
Maximize productivity.
5. Phase 1: Planning
Determine if a new system is needed
Three primary tasks:
Define the problem.
Suggest alternative solutions.
Prepare a short report.
6. Phase 2: System Analysis
In depth study of the existing system to
determine what the new system should do.
In addition to observation and interviews,
examine:
Formal lines of authority (org chart)
Standard operating procedures
How information flows
Reasons for any inefficiencies
7. Phase 3: System Design
It takes the initial input
For each requirements design elements will be
produced
It describes the software features and includes
hierarchy diagrams , screen layout diagrams
The output of the stage describe the new
system as a collection of modules or
subsystems.
8. Phase 4: System Development
Build the system to the design specifications
Develop the software
Acquire the hardware
Create manuals for users and operators
9. PHASE 5: SYSTEM TESTING
Test the new system
Module (unit) test - tests each part of
system
Integration testing - tests system as one
unit
10. Phase 6: System Implementation
Convert from old system to new system.
Train users
Compile final documentation
Evaluate the new system
User Training
11. Phase 7: System Maintenance
Physical repair of the system.
Correction of new bugs found.
System adjustments to environmental changes.
Adjustments for users’ changing needs
(adaptive).
Changes to user better techniques when they
become available (perfective).
12. SDLC MODELS
A framework that describes the activities performed at
each stage of a software development project.
Waterfall model
Iterative model
Prototyping model
Spiral Model
V model
13. WATERFALLMODEL
TheWaterfall Model was first Process Model to be introduced. It is also
Referred to as a linear-sequential life cycle model .
14. Strengths of Waterfall model
Strengths
Structure minimizes wasted effort.
Works well for technically weak or in
experienced staff.
Minimizes planning overhead.
Weakness
Inflexible
Only final stage produces documentation.
Backing up to address mistake is difficult.
15. Iterative Model
In Iterative model ,iterative process start with a simple implementation
Of a small set of the software requirements and iteratively enhances
the Evolving version until the complete system is implemented and
ready to be deployed
16. Strengths of Iterative model
Results are obtained early and periodically.
Parallel development can be planned.
Progress can be measured.
Less costly to change the scope/requirements.
Testing and debugging during smaller iteration is
easy.
17. WEAKNESS OF ITERATIVE MODEL
More resources may be required.
Although cost of change is lesser but it is not
very suitable for changing requirements.
More management attention is required.
System architecture or design issues may arise
because not all requirements are gathered in the
beginning of the entire life cycle.
Defining increments may require definition of
the complete system.
19. Strengths& weakness of Prototyping model
Strengths
Customers can see steady progress.
This is useful when requirements are changing
rapidly.
Weakness
It is impossible to know how long it will take.
There is no way to know the no of iterations
will be required.
20. Spiral Model
The Spiral model combines the idea of iterative development
With the systematic , controlled aspects of the waterfall model.
21. Strengths &Weakness of Spiral model
Strength
Early iterations of the project are cheapest
Risk decreases.
All iterations meets the project needs
Weakness
Complicated
Require attentive & knowledgeable
management
22. V- Model
The V-model is SDLC model where execution of processes happens in a
sequential manner in V-shape. It is also known as Verification and Validation
model.
23. Strengths of V model
Emphasize planning for verification and validation
of the product in early stages of product development
Each deliverable must be testable
Project management can track progress by
milestones
Easy to use
24. WEAKNESS OF V MODEL
Does not easily handle concurrent events
Does not handle iterations or phases
Does not easily handle dynamic changes in
requirements
Does not contain risk analysis activities
25. SOFTWARE DEVELOPMENT LIFE CYCLE:
THE ROLE OF TESTING
Software development life cycle (SDLC) is an integral
part of any software application development. Testing
has a lot of influence in SDLC.
In every company, testing is the most vital and precious
stage in the software development life cycle. But, the
technique by which it is performed, dissimilar from one
company to another company.
26. SDLC TESTING PHASE
The SDLC Testing phase is notionally designed to be
carried out after system development is complete.
With the help of different type of testing (e.g. assimilation tests,
element testing, user recognition testing system testing and
regression tests etc.) coder may produce a consistent and
reliable application. Testing also includes some process e.g. test
analysis, test plan, test design and test execution.
.
27. WHAT IS THE SDLC TESTING LIFE CYCLE?
SDLC Test Analysis Phase
SDLC Test Design Phase
SDLC Test Execution Phase
28. MOST IMPORTANCE OF TESTING IN SDLC
Recognition of Error and Faults
Resolves the errors and faults in the software application. These
errors may be in unit level or in system level.
Statistics to Shareholders and Status of Organization
Helps to know the condition of product and work standards.
Enhancement in Product Standards
Helps to know the real result and the probable result. It also helps to
pick up the standards of the software.
Technical Significance
Significant for technical characteristics of any SDLC as the software.
Free from any Risk
Free everyone from any risk.
29. CONTD…
Confirmation and Corroboration
Compare among standards of several software application.
Demonstrate Accessibility and Feasibility
Application is delivering to a select assembly of users and their
functioning with the application is noticed.
Avoid fault immigration
Prohibited all faults from immigrating to the following
progress stage.
30. WHATARE THE TYPES OF SDLC TESTING?
Acceptance Testing –
Alpha Testing –
Beta Testing –
Functional Testing –
Independent Verification and Validation –
Load Testing –
Security Testing –
31. SECURITY IN SDLC
Integrating security into the SDLC is essential for
developing quality software. While there are no standard
practices, these guidelines can help you develop a
custom process for a secure software development life
cycle.
Each phase of the SDLC is mapped with security
activities
Requirements Gathering
Security Requirements
Determine security needs
Determine privacy needs
32. Design
• Identify Design Requirements from security
perspective
• Architecture & Design Reviews
• Threat Modeling
Coding
• Coding Best Practices
• Perform Static Analysis
Testing
• Run security test cases
• Perform dynamic analysis
33. Deployment
• Server Configuration Review
• Network Configuration Review
Maintenance
• Continually monitor application security and update
as needed
• Utilize response plan as needed
34. SECURITY-ENHANCING LIFECYCLE
PROCESS MODELS
Enhance security through a repeatable and measurable
process
Provide guidance on secure software activities
Provide secure software development reviews
Include tactical resources
Provision the use of automation tools
Suggest roles for conducting the activities
Integrate with foundational software development
activities
35. FREE FLOW MODEL
In the framework of Free Flow the development process
of a software is augmented at every stage by incorporating
different matrices and allowing free flow of control in the
software development hierarchy in order to save time in
situations where the testing team need to interact with the
another team.
37. FREE-FLOW SDLC FEATURES
Requirement Capture
Prototype and High Level Diagrams
Module releases
–
Check-List Method
Well-Defined Architecture
Task and bug tracking system
38. CONCLUSION
There are many SDLC models such as, Waterfall, spiral,
iterative, V-shaped etc. used in various organizations depending
upon the conditions prevailing there
In this paper we have compared the different software
development life cycle models on the basis of certain features
like- Requirement, specifications, Risk involvement, User
involvement, Cost etc.
On the basis of these features for a particular software project
one can decide which of these software development life cycle
models should be chosen for that particular project. Selecting the
correct life cycle model is extremely important in a software
industry as the software has to be delivered within the time
deadline & should also have the desired quality.
39. FUTURE WORK
The new proposed framework is a Comparative
Analysis of Free Flow software methodology
with different SDLC model.
Free-Flow Model eliminates the risks and errors
in early stages through pipelined flow of processes
and control more than other SDLC model.
Number of matrices added to make the system
robust and increase its efficiency.
