1、Designation:E134005(Reapproved 2010)An American National StandardStandard Guide forRapid Prototyping of Information Systems1This standard is issued under the fixed designation E1340;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the
2、 year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This guide covers a rapid prototyping method fordeveloping information systems that is particularly relevant tosys
3、tems for the healthcare sector.Intended readers of this guideare people who develop information systems,and students andteachers of system development methods.1.2 Rapid prototyping is an approach to developing infor-mation systems which produce a working model more quicklythan conventional approache
4、s.Where conventional methodsconcentrate on preparing Requirements and design documentsthat describe the needed system,rapid prototyping methodsconcentrate on preparing a working prototype.Users anddevelopers learn the functional requirements and an appropri-ate system design by interacting with a se
5、ries of prototypes,each of which is rapidly produced from a starting framework orfrom an earlier version.A prototype can evolve into anoperational system,it can serve as an exact behavioral speci-fication of an operational system,or it can be used to explorethe feasibility of a new idea or design wh
6、ich can be incorpo-rated in a larger system.The method is rapid in preparing eachversion of the prototype,but the overall time required forsystem development may be more or less than the timerequired with conventional methods.1.3 Rapid prototyping is most appropriate when the Re-quirements or design
7、 for a system are not well understood,orwhen experimentation is required to explore some aspect ofsystem behavior.It is not appropriate in hazardous settings,orwhen the requirements are well understood.1.4 The guide recommends use of prototyping tools,but it isnot a standard for the tools themselves
8、.It does not coverexecutable specification tools.Transforming a prototype that isused to clarify Requirements into an operational system isdiscussed briefly in Section 8 and in detail in other referencedstandards(see 2.1).1.5 This standard does not purport to address all of thesafety concerns,if any
9、,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ANSI Standards:ANSI/MIL-STD-1815A Ada Programming Language2ANSI X3.9 P
