MAP-01-011 HFI Technical Guide - Human Factors Integration ...

MAP-01-011 – HFI Technical Guide (STGP 11)information (e.g. associated HFI activities and associated standards and guides)has been omitted for clarity.A3.1.1System Design ApproachesModel system design approaches exist, such as that defined inBS ISO/IEC 15288 ‘Systems engineering - System life cycle processes’ [Ref 34]and work is being conducted by the HFI DTC (2005), which is seeking to developa generic Defence Acquisition system design model.However, individual acquisition projects will be delivered through a variety ofcontractual arrangements (eg purchaser-prime supplier and sub-contractors,purchaser / provider alliances or possibly PFI arrangements) and differentproviders will adopt different approaches to the system design.Therefore this Annex does not assume any particular approach to system designand information is provided that will be common to many, if not all, designapproaches.A3.1.2The Impact of Applying a Technique etcThe techniques, method and tools described here constitute a portfolio ofresources that are available to support HFI development, realisation andvalidation. There is no suggestion that all or any of these techniques etc must beused, see also Sect A3.1.3 below. Whether or not a particular technique etc isneeded, or the extent to which a technique etc needs to be applied, is a projectspecificconsideration, requiring informed Human Factors Specialist input.Each technique, method or tool has associated resource and time implications.When considering the applicability of a particular technique etc to a givenAcquisition project, the reader should note that in most cases, the resourcesrequired to apply many of the listed techniques etc will be in proportion to the sizeand complexity of the project. Where a technique, method or tool is generallyresource-friendly, this is stated in the text. A much more important discriminatoris the dependency of many of the techniques etc on adequate source data orprior analysis, such as task analysis. These factors may differ depending onwhether a project is a green field design, or whether there is access to legacydata and experience. This should be taken into account when assessing thesuitability of a technique, method or tool to a particular application.The reader must note that inclusion in this Annex of a particular technique,method or tool does not constitute formal MoD approval or endorsement. Thesuitability of any HF technique etc must be re-assessed for each proposedproject-specific application, with input from HF professionals. Likewise, exclusionof a technique, method or tool from this Annex does not signify MoD disapproval.Additional information on design and assessment techniques, methods and toolsis available in Stanton et al ‘Handbook of Human Factors and ErgonomicsMethods’ [Ref 35].May 2006 Page A3-6 Issue 4
