MAP-01-011 – HFI Technical Guide (STGP 11)• Not as resource intensive as other techniques.• Disadvantages• Validity and reliability of the technique is questionable.• The use of such a simplistic technique in the design of a military commandand control may be questioned.• Whilst the techniques simplicity is the main advantage associated with itsuse, this leads to criticisms regarding depth of the analysis.• Although TCSD is not as resource intensive as other techniques, it is still atime consuming technique to apply.• Assembling the TCSD team may prove difficult. For example, a TCSDanalysis for the design of a military command and control system wouldrequire numerous specialists (Human Factors, military, design, systemoperators etc). Getting such a team together in one place at one timecould prove very difficult.• TCSD generates huge amounts of data.A3.3.5Design Scenario AnalysisDesign Scenario Analysis uses a storyboard approach to assist designers topropose, visualise, evaluate and modify design concepts. In its classic form, themethod identifies actors, assumptions about the environment, goals, objectives,sequences of actions and events. The questions Who, What, Why, Where andWhen are used to create the storyboard. Design Scenario Analysis is a flexible,powerful, low-cost vehicle to evolve and communicate system design information.The method requires appropriate scenarios to be defined and a multi-disciplinedteam to contribute to the process.• Advantages• Scenario analyses offer a quick and easy method of seeing the designconcept working in future contexts. This can help highlight any designflaws and future problems associated with the initial design.• Scenario analysis is a very flexible technique.• Scenario type analyses promote broad thinking.• Scenario analyses can provide a format for communicating designconcepts and issues between designers and design teams.• Quick, cheap and easy technique to apply.• Scenario type analysis can also be used to develop operator mentalmodels.May 2006 Page A3-22 Issue 4
