Task definition: Task I.1 Scope and bound the concept

  • I.1.1 Identify need, benefits and potential customers;

    I.1.2 Define desired output/control and input events that drive the application;

    Begin Task 1.1.2

  • I.1.2.1 FTR: Review written description of need

    I.1.2.2 Derive a list of customer visible outputs/inputs

    case of: mechanics

  • mechanics = quality function deployment
  • meet with customer to isolate major concept requirements;

    interview end-users;

    observe current approach to problem, current process;

    review past requests and complaints;

  • mechanics = structured analysis

  • make list of major data objects;

    define relationships between objects;

    define object attributes; mechanics = object view

    make list of problem classes;

    develop class hierarchy and class connections;

    define attributes for classes;

  • endcase

  • I.1.2.3 FTR: Review outputs/inputs with customer and revise as required;

  • endtask Task I.1.2

    I.1.3 Define the functionality/behavior that each major function is to perform;

    Begin Task 1.1.3

  • I.1.3.1 FTR: Review output and input data objects derived in task I.1.2;

    I.1.3.2 Derive a model of functions/behaviors;

    case of: mechanics

  • mechanics = quality function deployment
  • meet with customer to review major concept requirements;

    interview end-users;

    observe current approach to problem, current process;

    develop a hierarchical outline of functions/behaviors;

  • mechanics = structured analysis

  • derive a context level data flow diagram;

    refine the data flow diagram to provide more detail;

    write processing narratives for functions at lowest level of refinement;

  • mechanics = object view

  • define operations that are relevant for each class;
  • endcase

    I.1.3.3 Review functions/behaviors with customer and revise as required;

  • endtask Task I.1.3

    I.1.4 Isolate those elements of the technology to be implemented in software;

    I.1.5 Research availability of existing software;

    I.1.6 Define technical feasibility;

    I.1.7 Make quick estimate of size;

    I.1.8 Create a Scope Definition;

  • endTask definition: Task I.1


    Task definition: Task I.2 Develop a preliminary concept plan

  • U.1.1 Perform an adaptation criteria analysis;

    U.1.2 Select the software engineering task set;

    I.2.1 Make a rough estimate of work effort, duration, and other resources;

    I.2.2 Lay out a preliminary development schedule;

    I.2.3 Evaluate results of Tasks I.2.1 - I.2.2 to determine overall readiness;

  • endTask definition: Task I.2

     

    Task definition: Task I.3 Assess the technology/business risk

  • I.3.1 Identify technology/business risks associated with concept scope;

    I.3.2 Estimate the probability of occurrence for each risk;

    I.3.3 Estimate the project impact of each risk, should it occur;

    I.3.4 Develop a list of prioritized technology/business risks;

    I.3.5 Define an RM3 and update project plan to reflect risks;

  • endTask definition: Task I.3



    Task definition: Task I.4 Develop a proof of concept

  • I.4.Build a "concept model."1

    begin Task 1.4.1

  • review all concept documentation developed to date;

    case of: concept modeling approach

    concept modeling approach = paper model

  • I.4.1.1 Create a paper model (e.g., a mathematical model) of the technology or business concept;

    if concept can be modeled quantitatively then

  • determine quantitative features/parameters;

    build a mathematical model (e.g., spreadsheet);

    supplement with quantitative issues;

    incorporate risks (see Task I.3);

  • else

  • develop write-up (white paper) describing approach;

    address "why will this work?"

    incorporate risks (see Task I.3 );

  • endif

  • concept modeling approach = preliminary prototype

  • I.4.1.2 Create a mock-up prototype of the technology or business concept;

    define those characteristics that are user visible;

    if characteristics can be prototyped

  • then build preliminary prototype;

    else use different concept modeling approach;

  • endif

  • concept modeling approach = simulation model

  • I.4.1.3 Create a simulation model of the technology;

    define characteristics that can be simulated;

    if characteristics can be simulated

  • then build preliminary simulation model;

    else use different concept modeling approach;

  • endif

  • concept modeling approach = operational prototype

  • I.4.1.4 Build an operational prototype; {see also Task I.5}
  • endcase

  • endtask Task I.4.1

    I.4.2 Conduct a formal technical review;

    I.4.3 Make revisions based on the formal technical review;

    I.4.4 Re-assess risks based on lessons learned from concept model;

    I.4.5 Document the concept model;

  • endTask definition: Task I.4



    Task definition: Task I.5 Market the concept

  • I.5.1 Develop a "marketing presentation" for the concept.

    I.5.2 Reassess potential customers.

  • endTask definition: Task I.5



    Task definition: Task I. 6 Customer reaction to concept

  • I.6.1 Present concept representation to customers;

    I.6.2 If there are multiple potential customers, develop means for standardizing feedback;

    I.6.3 Record and analyze customer feedback;

  • endTask definition: Task I.6
