8. INTRODUCTION
Why Requirements Gathering & Analysis?
What Is Requirements Gathering?
Types of Software Projects
Requirements & Features
Types of Requirements

9. WHY REQUIREMENTS GATHERING &
ANALYSIS?
This common sense seems to disappear!
“Measure twice, cut once”
“Look before you leap”
 What do these sayings have in common?
They're about Thinking before Acting
 Why?
Because it Saves time, money and effort
It's plain common sense
Yet, when it comes to software development…

10. WHAT IS REQUIREMENTS GATHERING?
 A Process of Collecting the user needs
to Solve a problem or issues
and Achieve an objective
 An important Phase in a project life cycle
If the Requirements Gathering is not done properly
All below phases get incomplete
No matter how good the Design is
Requirements are the foundation of any Project
If you don’t know where you’re going, any road will take
you there!

11. TYPES OF SOFTWARE PROJECTS
 New Development: services & products
 Implementation: customization on existing software
(service or product)
 Research: proof of concept for new ideas
 Bug Fixing & Modifications: on existing software
(service or product)
 Maintenance & Support: on existing software
(service or product)

12. WHAT IS A REQUIREMENT?
 A requirement is a capability that a product must
possess to satisfy a customer need or objective
 A key component of any business project
 They help a project team define
 Goals
 Scope of the work
 They provide objective ways to measure the
project's success

13. BUSINESS REQUIREMENT
 A series of needs that must be fulfilled to achieve a
high-level objective
 Clear business requirements help ensure that the
end result of a project fulfills the stakeholders'
needs

14. FUNCTIONAL REQUIREMENT
 A detailed breakdown that explains how the
outcome of a project will operate to meet the
specified business requirements
 Include a list of the steps that each user will take in
the new system
 The functional requirements for a project are
defined and developed after the project's business
requirements have been established

15. BUSINESS REQUIREMENT VS. FUNCTIONAL
REQUIREMENT
Upgrade the manual payroll process by switching to an
automated payroll process
 Business requirements
“Implement a computerized system that reduces errors and
increases efficiency by calculating employees' wages,
withholding required deductions and paying the employee the
amount she is owed.”
 Functional requirements
 How many employees the system must accommodate
 Are they hourly, salaried or both
 What a pay period is
 What states' tax

16. NON-FUNCTIONAL REQUIREMENTS
 What an organization needs to do to support the
project's outcome during and after implementation
 Examples:
 Hardware
 Software
 Performance
 Number of normal and concurrent users
 Page response time
 Usability
 Cultural aspects
 Availability
 Reliability
 Maintainability
 Extensibility
 Security…

17. WHAT IS A FEATURE?
 A set of logically related requirements that allows
the user to satisfy an objective
 A feature tends to be a higher-level objective than a
requirement
 A requirement tends to be granular, and is written
with the implementation in mind
 A feature is something you’ll print on a detailed
datasheet of your product

18. FEATURE VS. REQUIREMENT
 Feature
 Online shopping cart
 Requirements
 User shall be able to add books to online shopping cart
 User shall be able to remove books from online
shopping cart
 User shall be able to view books in the online shopping
cart at any time
 User shall be able to start his checkout from the
shopping cart

19. I’m trying to write a DOS bat file that runs an Access
macro to import a CSV output file from my COBOL
program. Any help would be appreciated!

20. TYPES OF REQUIREMENTS
 Conscious Requirements
Stakeholder is aware of
 Unconscious Requirements
Stakeholder knows the requirement so well that he
thinks that it's not worth mentioning
 Undreamed Requirements
Stakeholders does not ask for, either because he
thinks they are not possible or because they are new
ideas that have occurred to them

21. COMMON ISSUES & CHALLENGES
Why Do Projects Fail?
Requirements Gathering Challenges
Requirements Volatility Causes
What Causes Changes to Requirements?
Scope Creep

22. The sooner you begin coding the later you
finish

23. WHY DO PROJECTS FAIL?
A Standish group research report says that:
 31% of all projects are cancelled before they ever
get completed
 53% of projects cost almost twice their original
estimates

24. REQUIREMENTS GATHERING
CHALLENGES
A user is somebody who tells you what they
want the day you give them what they
asked for

25. STAKEHOLDERS ISSUES
 Users don't understand what they want
 All requirements are critical, no priority is defined
 Scope and Vision not clearly defined
 Users won't commit to a set of written requirements
 Users change requirements after the cost and schedule
have been fixed
 Communication with users is slow
 Users often do not participate in reviews
 Users are technically unsophisticated
 Users don't understand the development process
 Users don't know about present technology

26. ENGINEER/DEVELOPER ISSUES
 Technical personnel and end users may have
different vocabularies
 Consequently, they may wrongly believe they are in
perfect agreement until the finished product is
supplied
 Engineers and developers may try to make the
requirements fit an existing system or model, rather
than develop a system specific to the needs of the
client
 Analysis may be often carried out by engineers or
programmers, rather than personnel with the
people skills and the domain knowledge to
understand a client's needs properly

27.  What if these challenges were not beaten?
The final product will not be Delivered to the customer
Successfully in Time
 Why?
Because the impact of the above points is huge in the
product’s life cycle

28. “What if users developed their own applications?!”

29. What is not on paper has not been said

30. REQUIREMENTS VOLATILITY CAUSES
 Internal Factors
 Not capturing requirements from all relevant
stakeholders
 Not using right requirement capturing technique
depending on the context
 Not capturing all relevant details
 Not having measures such as check-list to ensure
completeness of requirements captured
 Not having measures to ensure clarity
 External Factors
 Market driven

31. WHAT CAUSES CHANGES TO
REQUIREMENTS?
 Requirements errors, conflicts and inconsistencies
during analysis
 Evolving customer/end-user knowledge of the system
 Technical, schedule or cost problems
 Changing customer priorities
 Changing business environment
 Emergence of new competitors, staff changes, etc.
 New laws, regulations
 Environmental changes
 Organizational changes
 Changes in structure and processes
 New technology (technology push)

32. SCOPE CREEP
 Refers to uncontrolled changes or continuous
growth in a project's scope
 This can occur when the scope of a project is not
properly defined, documented, or controlled
 It is generally considered harmful

33. WHO IS THE BUSINESS ANALYST?
The Analyst Job
Responsibilities
Business Analyst Qualifications

34. THE ANALYST JOB
 Demonstrate the ability and inclination to tolerate
 chaos
 ambiguity
 and lack of knowledge
 and to function effectively in spite of them

35. RESPONSIBILITIES

43. HOW TO DO THE JOB?
Software Development Lifecycle (SDLC)
Requirements Management Process
Requirements Gathering Activities
Change Management
Requirements Traceability
Signoff

44. SOFTWARE DEVELOPMENT LIFECYCLE (SDLC)

45. REQUIREMENTS MANAGEMENT PROCESS
Elicitation
Analysis
Recording
Validation
Change Management
Traceability
Signoff

46. REQUIREMENTS GATHERING ACTIVITIES
Eliciting Requirements
Communicating with users to determine their requirements
Analyzing Requirements
Determining whether the stated requirements are unclear, incomplete,
ambiguous, or contradictory and then resolving these issues
Recording Requirements
Requirements may be documented in various forms
 Natural-language documents
 Use cases
 User stories
 Process specifications
Validating Requirements
Checking that a product, service, or system meets requirements and that it
fulfills its intended purpose

47. A user will tell you anything you ask about,
but nothing more

48. CHANGE MANAGEMENT
 The process of managing the changes to
requirements
 Hard problem because of continuous changes
during development process
 The principal concerns are
 Managing the relationships between requirements
 Managing priorities between requirements
 Managing changes to agreed requirements
 Managing the dependencies between different
documents
 requirements document
 other documents produced in the systems engineering process

49. REQUIREMENTS TRACEABILITY
 Requirements cannot be managed effectively
without traceability
 Traceable means knowing about
 Who suggested the requirement
 Why exists the requirement
 What requirements are related to it
 How relates that requirement to other information such
as:
 Mockups
 System design
 Implementations
 User documentation

50. SIGNOFF
 Final & most important step in requirements
gathering process
 Requirements should be freezed
 Later request for changes should be treated
separately
 Technical opinion should be involved
 Review with customer before signoff

51. REQUIREMENTS GATHERING
TECHNIQUES
Requirements are the What
Design is the How

52. REQUIREMENTS GATHERING TECHNIQUES
 4 out of 5 software development projects go over
time, over budget or don’t deliver expected results
 Poor requirements account for 71% of software
project failures
 It pays to put in the effort upfront to minimize the
risk of failure
 The question is, how do we achieve this?
 There is no perfect method for gathering and analyzing
requirements
 If there was, we'd all be using it
 Rather, there are many approaches to choose from…

53. REQUIREMENTS GATHERING TECHNIQUES
 A structured approach to requirements
management resolves these problems
 Develop SMART objectives which nearly
guarantees the success of the project
 Scientific approach requires a constant description
of all activities, objectives and corrective measures
to counter potential loopholes

54. REQUIREMENTS GATHERING TECHNIQUES

Observes the
business users
Understands the day
to day activities
Capture/documents
the requirements
Get signoff from
customer

81. TOWARDS A BETTER OUTPUT
Guidelines
Tips

82. GUIDELINES
Users don't know what they want until you show it to them

83. GUIDELINES:1
 Focus & clarity
 Clearly state the objective & define the scope
 Clarify what the project does and does not cover
 A format for specifying requirements
 Use whichever method works for you
 Understanding is the most important outcome
 Not all formats of requirements documentation are equal
 Requirements document author
 Writing skills
 Balance understanding the project domain against
understanding the process of software development

84. GUIDELINES:2
 Requirements language
 Use the same language as your client
 If the language is consistent, it greatly lowers the risk of
requirements misinterpretation
 Accuracy is critical
 Accurately reflect client needs
 Walk the client through the requirements
 It costs more to fix things in testing than in the requirements
phase
 Minimize the risk of errant interpretation
 Ensure everyone has the same understanding
 Use diagrams, pictures, or sample data illustrating
requirements meaning
