beta testing keynote speech mua november2011
DESCRIPTION
This was a keynote speech delivered by Dr Sanjoy Sanyal to the students, faculty and administration at the MUA Research Symposium in Fall (November) 2011 in Medical University of the Americas, Nevis. Two clinical systems, developed by the author himself, were also demonstrated; Automatic Staging of Breast Cancer and Determining the Risk of Cardiovascular Event in 5 Years.TRANSCRIPT

Contents• Hitchhiker’s Guide to the Galaxy – Insanely great!
• Technological Systems in Medical Settings
• Systems Development Processes
• Systems Testing Processes
• Usability / Usefulness, Usability Testing Instruments
• InQsit Online Examination System: CSUQ, ETC, Beta testing, Score Grading, Preliminary results
• InQsit for Faculty
• Demonstration of 2 Clinical Systems (External)
• Conclusion – What was that again?
SMART: A project should be
• Simple
• Measurable
• Achievable
• Realistic
• Time-bound
Three projects are described
• Beta testing of an Online Examination system
• System for Automated staging of Breast cancer
• System for giving adjusted risk of CV event
Systems defined
Technological systems• Medical care settings:
Strategic (DSS, EIS); Tactical (MIS); Operational (PAS; Clinical EMR / EHR / EPR, CPOE, ETP, LIS, PACS)
Technological Systems• Telemedicine –
Telematics systems
• Subject / Task based systems (OT, Admission-Discharge systems); Simulation systems (Acute capability model, Pollution Asthma project, Renal services simulation)
• Medical education setting: Many of above; LMS (Moodle); Online lecture systems; Online Exam systems (Questionmark, InQsit)
Systems Development
Systems Develop
ment
• Multiple iterations till Alpha / Internal Acceptance Testing
Testing ProcessesAlpha (α) testing: Internal Acceptance Testing
• Simulated / actual operational testing by independent team at developers' site
• It is a form of Internal Acceptance testing, before it goes to Beta (β) testing
Beta (β) testing:
• Comes after Alpha (α) testing
• β versions released to limited audience outside programming team, or made available to open public to increase number of feedback
• Ensures product has few faults / ‘bugs’
Beta testing
Testing processes(External) Acceptance testing:
• Can be conducted by end-user, customer or client
• Whether or not to accept product
Regression testing:
• After modifying S/W, re-run previously passing tests
• Ensures modifications have not caused regression of previous functionality
– Sanity testing: Quickly checking for bizarre behaviour
– Smoke testing: Testing for basic functionality
INQSIT online exam system
Usability – Usefulness – Users –Qs• Usability: How easy is it for me to use the system?
• Usefulness: Does it make my work easier?
• Users: Consultative; Representative; Consensus
Usability Testing Instruments• QUIS (27): Questionnaire for User Interface Satisfaction –
Chin et al
• PUEU (12): Perceived Usefulness and Ease of Use – Davis
• NAU (5): Nielsen’s Attributes of Usability – Nielsen
• NHE (10): Nielsen’s Heuristic Evaluation – Nielsen
• CSUQ (19): Lewis
• ASQ (3): After-scenario Questionnaire – Lewis
• PHUE (13): Practical Heuristics for Usability Evaluation – Perlman
• PUTQ (100): Purdue Usability Testing Questionnaire – Lin et

Score gradingScore 19 - 56
Dis-satisfied
We are concerned that you are not entirely satisfied with the online examination system. We would like you tell us about it in more detail.
57 - 95
Neither +/-
It seems you are still double-minded about the new online exam system. Is there anything we can do to help you make up your mind?
96 - 133
Satisfied We are happy to note that you are satisfied with the new online exam system. We can assure you, your faith in the system is quite justified.
Beta test preliminary results
Beta Test Preliminary Results• Average
question-wise score = 5.33 / 7 (Mildly-Moderately agree)
• Average total score = 101.2 / 133 (Satisfied)
Beta Test Preliminary Results
• Qs 9: The system gives error messages that clearly tells me how to fix problems (This was an ambiguous question)
