Requirements Writing

SMART Criteria

Letter	Meaning	Test
S	Specific	Is it clear what's needed?
M	Measurable	Can we verify it's done?
A	Achievable	Is it realistic?
R	Relevant	Does it support objectives?
T	Time-bound	Is there a deadline?

Good vs. Bad Requirements

Bad	Problem	Better
"System should be fast"	Not measurable	"Page load < 2 seconds"
"Easy to use"	Subjective	"Complete task in < 3 clicks"
"Handle all cases"	Unbounded	"Support cases A, B, C"
"Similar to competitor"	Vague	"[Specific features listed]"
"Should probably..."	Uncertain	"Must" or "Should" (MoSCoW)

Requirement Attributes

Attribute	Purpose
ID	Unique identifier (REQ-001)
Description	What is required
Priority	MoSCoW or numeric
Source	Who requested it
Rationale	Why it's needed
Acceptance Criteria	How to verify
Dependencies	Related requirements
Status	Draft/Approved/Implemented

Elicitation Techniques

Technique Selection

Technique	Best For	Effort
Interviews	Deep understanding, complex topics	High
Workshops	Consensus, group decisions	Medium
Surveys	Broad input, quantitative data	Low
Observation	Understanding real workflows	High
Document Analysis	Existing systems, regulations	Low
Prototyping	Validating concepts, UI	Medium
Focus Groups	User perspectives, reactions	Medium

Interview Best Practices

Prepare questions in advance
Start broad, then specific
Use open-ended questions
Listen more than talk (80/20)
Probe with "Why?" and "How?"
Summarize and confirm understanding
Document immediately after

Workshop Facilitation

Phase	Activities
Open	Objectives, agenda, ground rules
Diverge	Brainstorm, generate options
Converge	Prioritize, decide
Close	Summarize, next steps, thank

Use Case Development

Use Case Template

Use Case: [UC-001] [Name]
Actor: [Primary actor]
Precondition: [What must be true before]
Trigger: [What initiates the use case]

Main Flow:
1. Actor does X
2. System responds with Y
3. ...

Alternative Flows:
2a. If condition, then...

Exception Flows:
2b. If error, then...

Postcondition: [What is true after]
Business Rules: [Applicable rules]

Use Case Levels

Level	Scope	Example
Summary	Multiple sessions	"Manage Customer Account"
User Goal	One sitting	"Place Order"
Subfunction	Part of a step	"Validate Address"

Process Analysis

Current State Analysis

Map as-is process (BPMN, swimlane)
Identify pain points
Measure current performance
Find root causes
Quantify improvement opportunity

Process Mapping Notations

Notation	Best For
BPMN	Detailed, technical processes
Swimlane	Cross-functional workflows
Value Stream	Lean analysis
SIPOC	High-level overview

SIPOC Template

Suppliers	Inputs	Process	Outputs	Customers
Who provides?	What's needed?	High-level steps	What's produced?	Who receives?

Gap Analysis

Gap Analysis Framework

Current State → Gap → Future State
     │           │          │
     ▼           ▼          ▼
  As-Is     What needs   To-Be
  Process   to change    Vision

Gap Categories

Type	Examples
Process	Missing steps, manual work
Technology	System limitations
People	Skills, capacity
Data	Quality, availability
Policy	Rules, compliance

Acceptance Criteria

Gherkin Format

Given [precondition]
When [action]
Then [expected result]
And [additional result]

Acceptance Criteria Checklist

Testable — Can write a test case
Clear — Unambiguous language
Complete — Covers happy path and edges
Independent — Doesn't require other criteria
Valuable — Ties to user need

Traceability

Traceability Matrix

Req ID	Business Objective	Design	Test Case	Status
REQ-001	OBJ-01	DES-005	TC-012	Passed

Traceability Benefits

Ensure all requirements implemented
Impact analysis for changes
Test coverage verification
Audit compliance evidence

Prioritization Techniques

MoSCoW

Priority	Meaning	Guidance
Must	Critical for success	~60% of effort
Should	Important, not critical	~20% of effort
Could	Nice to have	~20% of effort
Won't	Out of scope (this release)	Documented

Value vs. Effort Matrix

High Value │ Quick Wins │ Major Projects │
           │ (Do first) │ (Plan carefully)│
Low Value  │ Fill-ins   │ Avoid           │
           │ (If time)  │ (Don't do)      │
           └────────────┴─────────────────┘
             Low Effort   High Effort

Kano Model

Type	If Present	If Absent
Basic	Expected, no delight	Dissatisfied
Performance	More is better	Less is worse
Delighter	Unexpected joy	Not missed

Common BA Pitfalls

Pitfall	Prevention
Solution jumping	Ask "why" before "how"
Missing stakeholders	Stakeholder analysis early
Gold plating	Tie everything to objectives
Assumption blindness	Document and validate assumptions
Scope creep	Change control process
Analysis paralysis	Timeboxed analysis, iterate
