UX from 30,000ft - COMP33512 - Lectures 17 & 18 - Week 9 - 2013/2014 Edition #comp33512

Published on

IRL - UX work design espoused by the ‘standard’ textbooks often assume perfection in the process. They assume that there are no limitations on the time required for the work to occur; they assume that there are no limitations on the skills required for the work to occur; and they assume that there are no limitations on the instruments required for the work to occur – to name but three.

  2. 2. Preamble In Real Life Break! Optimism Silver Bullets Wrapping Up Discussion Topics Coursework # 3 ‘Voice Loops as Cooperative Aids in Space Shuttle Mission Control’ [Watts et al., 1996] (10 Marks) this paper shows just how far UX and the techniques which it inherits from human computer interaction can go. We are mainly concerned with systems and objects which are purely commercial, however, in this case failures in the human interface can have serious consequences for a real-time mission, including the loss of the vehicle. Further, these kind of UX techniques can also be found in other critical interface components such as those controlling nuclear power stations or fly-by-wire aircraft.

  14. 14. Preamble In Real Life Break! Optimism Silver Bullets Wrapping Up Optimism We are Optimistic - we think we can create software that will help users / make their lives better / make us money (?-yuck!). We think we will bash every bug, satisfy every requirement, develop elegant and beautiful code. This Optimism can be our downfall! The User Experience from 30,000ft Optimism 14 / 25

  19. 19. Preamble In Real Life Break! Optimism Silver Bullets Wrapping Up Optimism – Lessons from Brooks Second System Effect ‘When it comes to creating the second version the developers are buoyed by their expertise and mastery of the first system and try to cram in as many of the flourishes and embellishments from the first system as is possible’ The User Experience from 30,000ft Optimism 17 / 25

  23. 23. Preamble In Real Life Break! Optimism Silver Bullets Wrapping Up Optimism – Lessons from Brooks Throwaway Project ‘You should plan to throw away the first version of anything that you create, be it a user interface design or an engineered interaction. The first version often enables an understanding of the system and aspects of the system development but it should not be confused with a real live deployable user experience.’ The User Experience from 30,000ft Optimism 19 / 25
  24. 24. Preamble In Real Life Break! Optimism Silver Bullets Wrapping Up Optimism – Lessons from Brooks Throwaway Project ‘Agile methods, and to some degree the iterative design cycle, makes accommodation for these constantly changing factors. But you should also realise that even though the project planner or manager may have agreed a specification, that specification is unlikely to be the one delivered.’ The User Experience from 30,000ft Optimism 19 / 25
  25. 25. Preamble In Real Life Break! Optimism Silver Bullets Wrapping Up Optimism – Lessons from David Parnas Changes Happen ‘One thing that has come out of the work of David Parnas, and in some cases may be transferred back, is the ability to think of a software project as a family of related products; Parnas suggests this method anticipates enhanced sideways extensions and versioning.’ The User Experience from 30,000ft Optimism 20 / 25
  26. 26. Preamble In Real Life Break!

  27. 27. Preamble In Real Life Break! Optimism Silver Bullets Wrapping Up Silver Bullets – Lessons from Brooks There is no single development, in either technology or management technique, which by itself promises even a tenfold improvement within a decade in productivity, in reliability, in simplicity; and We cannot expect ever to see two-fold gains every two years. The User Experience from 30,000ft Silver Bullets 21 / 25
  28. 28. Preamble In Real Life Break! Optimism Silver Bullets Wrapping Up Silver Bullets – Conclusions ‘While there might be no silver bullet (indeed the silver bullet may take away some of the challenge, and therefore our fun), the best advice I have is to always keep in mind the pessimistic view of an optimistic visionary ‘most people are fools, most authority is malignant, God does not exist, and everything is wrong.’.’ The User Experience from 30,000ft Silver Bullets 22 / 25
  29. 29. Preamble In Real Life Break! Optimism Silver Bullets Wrapping Up Pop Quiz for next week... 1. You are suffering from the ‘Too–Little–Time’ constraint and need to get a formative evaluation with 20 people (employees of the factory commissioning your new production line software) underway very quickly. At this stage you only need qualitative results – how would you go about getting this information in the fastest time possible, and why would you be cautious? 2. What are commissioning constraints? 3. What is real world work limited by? 4. Why is optimism often a bad mindset to have when it comes to planning UX work? 5. Describe the ‘Second System Effect’?
