Both the software engineering and the user experience design skillset is essential for the creation of high quality software products. Project managers must recognize when the user interface is important for the
success of the software. And they must have some methods & tools on
the list that support project success.

This enables you in decision making and leading the project in the right direction.Project Management with Usability Engineering Methods | Dr. Thomas Memmel 7. February 2012 Slide 13 © Zühlke 2012
  14. 14. Project Management TasksExamples• Requirements management • Definition of requirements• Scope management • Understand vision and needs• Change Request management • Build the right solution• Cost management • Assess and decide about changes• Time management • Goal-oriented spending• Quality management • Delivery, time-to-market• Communications management • Software quality (e.g. ISO 9126, Usability)• Risk management • Common denominator • Stakeholder management • Efficient team collaborationProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.

  15. 15. Challenges in Project ManagementTypical Issues in PMP Life• Poor quality of requirements • Quality of the software and the user interface is evaluated too late• Inaccurate project vision • Bad user acceptance• Communication gap between Business & IT • Little interdisciplinary teamwork across disciplines (e.g. design vs. development• Pressure of time, especially in vs. business) case of error• Consequences of unexpected events• Costly changes at later stage• Test management• Conflicts among stakeholdersProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.

  16. 16. Challenges in Project ManagementCosmetic Software Surgery User interface cosmetics will not change the behaviour of the software, but only add, move or hide pixels across the screen Surface alteration is costly and difficult. The chance of failure is high – and may result in an even more fake or ugly look & feelProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.

  21. 21. Contextual InquiryBasisData Gathering with Users for Decision Making on FRs / NFRsGoal• Understand users and their needs (also tacit knowledge)• Understand current work styles and processes• Be objectiveSimple Approach• Go where the users are doing their work• Observe users during their work• Talk with users About their work• In “empirical partnership”Project Management with Usability Engineering Methods | Dr. Thomas Memmel 7. February 2012 Slide 21 © Zühlke 2012
  22. 22. Contextual Inquiry • Find hard facts • Listen to users – Instead of listening to assumptions • Check interpretations of the development team and stakeholders (e.g. sources of requirements) with real users within the context of use • Deduce consequences for product vision and design from the given evidence • Document implications • Have traceability from design to learned facts and vice versaProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.

February 2012 Slide 31 © Zühlke 2012
  32. 32. Paper Prototyping • Rapid feedback while the design is still (literally) “on the drawing board" • Clarify requirements through simulation • Detect misunderstood requirements and usability problems very early • Promote communication between designers and users • One of the cheapest and fastest visual techniques • Useful for any type of human-computer interface • Only minimal resources and materials requiredProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.

  34. 34. Analyse & Specify User RequirementsFor Example Relevant During Benefits / ROI, e.g.• Definition of requirements • Reflect implementations with persons• Decision making • Know your users (needs)• Solution design • Personas are cheap “on-site users”• Development • Discuss ideas with non-technical stakeholders • Communicate informally • Externalize designs • Reduce risk – Build the right productProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.

  37. 37. Why UI Prototyping?Beyond Text-Based Requirements & Specifications • Text has limited expressivity with regards to interaction design • Tons of paper make needs & requirements intransparent • People do not see the wood for the trees • Consequences of requirements not realized until they can be experienced • Make the impact of changes to requirements obviousProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7. February 2012 Slide 37 © Zühlke 2012
  38. 38. Why UI Prototyping?See and interactions before they are built • Don’t loose time discussing intangible requirements • Visualize ideas in front of users and stakeholders • See and interact with applications before they are built • Consider alternate designs • Avoid premature decisions • Visualize and change requirements as long as it is cheap and easyProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.

  51. 51. Agile + UsabilityThe Best of Two WorldsSome goals of Agile projects• Deliver in defined time and budget…• Develop the simplest but most functional solution…• …that fulfils the requirements of the customerOne important goal of Usability Engineering• Develop software that works and deliver the best possible usabilityCombined• Do not just deliver the simplest solution in the most efficient way (Agile)• But to also reach a high usability and user experienceProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.

  52. 52. Agile + UsabilitySome Facts• Scrum & UX methods demand a product vision in the beginning• The agile way of handling requirements in a non-waterfall fashion perfectly matches with UX• Design space is kept open• Developers and UX experts learn from small releases and can continuously improve the product quality• Delivered releases can be usability tested and assessed while applied in the context of useProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.

  53. 53. User Stories with Usability Description of user needs (e.g. reference to persona) User Story Discussion about requirements in detail Card (btw. user/customer and developer). Conversation Supported by prototyping. Confirmation Acceptance tests, e.g. also usability tests based on usability goals etc.Project Management with Usability Engineering Methods | Dr. Thomas Memmel 7. February 2012 Slide 53 © Zühlke 2012

  56. 56. Project Management with UsabilitySummary / Discussion• Develop the right product • Additional complexity for the project• Define scope and • Additional costs for UX personnel deliverables with real users • More changes: user feedback is• Create usable and iterative aesthetically pleasing results • Demands more agility• Improve software quality • Not all feedback is valuable• Reduce risk due to high user • Some stakeholders will know it better acceptance and validation• Reduce textual specification and Documentation Effort Applied in the right way – UX• Bridge the Gaps with Visual ROI will be significant artefacts and CommunicationProject Management with Usability Engineering Methods | Dr. Thomas Memmel 7.
