Mobile App Onboarding Experience

Acceptance Criteria Analysis: Mobile App Onboarding

Criterion 1: “Tutorials should be engaging”

Status: ❌ NOT TESTABLE
Issues:

• “engaging” is subjective and unmeasurable
• No definition of what engagement looks like
• No behavioral or quantitative metrics

Testable Rewrites:
✅ Option A (Completion Rate):
“At least 80% of users complete the tutorial sequence without skipping”

• Measurable: Yes (80% completion threshold)
• Observable: Yes (analytics track completion vs skip)
• Specific: Yes (defines engagement as completion behavior)

✅ Option B (Interaction Time):
“Users spend at least 30 seconds on each tutorial screen before proceeding”

• Measurable: Yes (30 seconds per screen)
• Observable: Yes (time tracking)
• Specific: Yes (defines engagement as attention duration)

✅ Option C (User Feedback):
“Tutorial receives satisfaction rating of 4.0+ out of 5.0 from users who complete onboarding”

• Measurable: Yes (4.0/5.0 threshold)
• Observable: Yes (post-tutorial survey)
• Specific: Yes (defines engagement through satisfaction)

Recommendation: Option A (completion rate is strongest indicator of engagement)

Criterion 2: “Navigation should be intuitive”

Status: ❌ NOT TESTABLE
Issues:

• “intuitive” is subjective
• No measurable usability metric
• No definition of navigation success

Testable Rewrites:
✅ Option A (First-Time Success):
“90% of users complete onboarding without tapping ‘Back’ or ‘Help’”

• Measurable: Yes (90% threshold, specific actions)
• Observable: Yes (track navigation patterns)
• Specific: Yes (defines intuitive as linear progression)

✅ Option B (Task Completion):
“Users reach the final onboarding screen within 5 minutes without errors”

• Measurable: Yes (5 minute threshold, zero errors)
• Observable: Yes (time tracking and error logging)
• Specific: Yes (defines success path)

✅ Option C (Platform Consistency):
“Onboarding uses standard iOS/Android navigation patterns (swipe, Next button, progress indicators)”

• Measurable: Yes (presence of standard elements)
• Observable: Yes (visual verification)
• Specific: Yes (follows platform conventions)

Recommendation: Use Option A + Option C for both behavioral success and design standards

Criterion 3: “Performance should be smooth”

Status: ❌ NOT TESTABLE
Issues:

• “smooth” is subjective
• No performance metrics defined
• No device compatibility specified

Testable Rewrites:
✅ Option A (Frame Rate):
“All animations and transitions run at 60 FPS on iPhone 12+/Samsung S21+ devices”

• Measurable: Yes (60 FPS, specific devices)
• Observable: Yes (frame rate monitoring tools)
• Specific: Yes (defines smoothness as frame rate)

✅ Option B (Animation Timing):
“Screen transitions complete within 300ms with no visible lag”

• Measurable: Yes (300ms threshold)
• Observable: Yes (can be timed)
• Specific: Yes (defines transition performance)

✅ Option C (Touch Response):
“Touch interactions (tap, swipe) trigger visual feedback within 100ms”

• Measurable: Yes (100ms threshold)
• Observable: Yes (response time verification)
• Specific: Yes (defines interaction responsiveness)

Recommendation: Use all three to comprehensively define “smooth” performance

Criterion 4: “Loading should be reasonable”

Status: ❌ NOT TESTABLE
Issues:

• “reasonable” is subjective
• No time thresholds defined
• No loading context specified

Testable Rewrites:
✅ Option A (Initial Load):
“Onboarding first screen loads within 2 seconds after app launch”

• Measurable: Yes (2 second threshold)
• Observable: Yes (load time tracking)
• Specific: Yes (defines initial experience)

✅ Option B (Screen Transitions):
“Each subsequent onboarding screen loads within 500ms”

• Measurable: Yes (500ms threshold)
• Observable: Yes (can be timed)
• Specific: Yes (defines navigation speed)

✅ Option C (Asset Loading):
“Tutorial images and videos load within 1 second on 4G connection (10 Mbps)”

• Measurable: Yes (1 second, specific network speed)
• Observable: Yes (asset load time monitoring)
• Specific: Yes (defines media loading expectations)

Recommendation: Use Option A + Option B for comprehensive loading coverage

Summary

Original Criteria: 4 statements, 4 not testable (100% vague)
Testable Criteria Generated: 12 specific, measurable alternatives

Testability Standards Met:
✅ Clear pass/fail conditions for all criteria
✅ Measurable thresholds defined (seconds, percentages, FPS)
✅ Observable behaviors specified (what QA can verify)
✅ No subjective terms remaining

Recommended Final Acceptance Criteria:

1. At least 80% of users complete the tutorial sequence without skipping
2. 90% of users complete onboarding without tapping ‘Back’ or ‘Help’
3. Onboarding uses standard iOS/Android navigation patterns (swipe, Next button, progress indicators)
4. All animations and transitions run at 60 FPS on iPhone 12+/Samsung S21+ devices
5. Screen transitions complete within 300ms with no visible lag
6. Touch interactions (tap, swipe) trigger visual feedback within 100ms
7. Onboarding first screen loads within 2 seconds after app launch
8. Each subsequent onboarding screen loads within 500ms

Quality Improvement: From 0% testable → 100% testable
