2. Estimation
How to plan everything

3. Why?

4. Why do we need estimate our tasks?
• Resource Allocation
• Project Planning
• Quality Assurance
• Stakeholder Communication
• Risk Management

5. Problems?

6. Common Issues in Test Estimation
• Underestimation
• Overestimation
• Lack of Clarity
• Volatile Requirements
• Technical Challenges
• Skill Gaps
• Ignoring Non-Functional Testing
• Ignoring Features-Dependencies

7. What?

8. Factors Influencing Test Estimation
• Complexity of the Project
• Level of Quality of the Project
• Team Experience, Trainings, Education
• Tools and Technologies Used
• External Dependencies
• Stability of Project Team

9. Factors Influencing Test Estimation
• Historical Data From Previous Projects
• Process Maturity
• Test Data Management
• Test Environment Management
• Project Documentation Management
• Custom Hardware or Software Availability
• Release cycle
• Technical debt
• Tests flakiness

10. When?

11. When do we need to estimate?
• Start of the Project
• Ongoing Tasks
• Test Closure

12. New project

13. New project
• Review Software Design Document
• Domain Specific Onboarding
• Creating Test Plan, Test Strategy
• Risk analysis
• Setup Project Framework (template)
• Configure Local Test Environment
• Configure CI/CD

14. Ongoing project
• Planning
• Analysis
• Test design
• Test implementation
• Test execution
• Bug reporting and retesting

15. Test closure activities
• Test Reports Generation
• Test Cases Delivering
• Delivery Report Generation
• Retrospective View

16. How?

17. Techniques for Test Estimation
• Intuition
• Tester/Developer Ratio
• Comparative Estimation
• Expert Judgment
• Use Case Point Method
• Wideband Delphi
• Three-Point Estimation
• Function Point Analysis
• Test Point Analysis
• Work Breakdown Structure (WBS)

19. Techniques for Test Estimation
• Tester/Developer Ratio

20. Techniques for Test Estimation
• Comparative Estimation

21. Techniques for Test Estimation
• Expert Judgment

22. Techniques for Test Estimation
• Use Case Point Method

23. Techniques for Test Estimation
• Wideband Delphi

24. Techniques for Test Estimation
• Three-Point Estimation
• E = (O + P + 4*M) / 6
• S.D. = (P - O) / 6
• Approx.time = E±S.D.
