  11. 11. • Be Informed estimation general• Zooming in on fpa
  12. 12. Starting points Be Informed estimation discover• Combining different estimation techniques - usage of historic project metrics for model estimation - analogy estimation based on project archetype and model archetype define - model based FPA• In line with Be Informed implementation method: design - Estimation at end of Discover, Define and Design phase with increasing reliability and accuracy - Use right terminology for applied Be Informed patterns and characterization of business knowledge domains, business functions and components.• Support in project estimation of Be Informed implementation core - framing and qualifying of scope application - estimation of scale and scope - estimation of productivity and cost drivers• Support in project control of Be Informed implementation - managing project scope by monitoring characteristics - tracking of productivity vs. size (and therefore time) detail 12
  13. 13. Characteristics and Metrics• Characteristics describe a project on content properties  unambiguous characterization of project -> estimate based on analogy  enables monitoring on content properties• Metrics describe a project in quantitative properties  Metrics defined on substantive and statistical grounds -> estimate based on models/formulas  Enables monitoring on quantitative properties possible• Monitoring of characteristics by : • Repeated determination: holds the target operating model still the same components ? Is the number of core taxonomies still the same ? Do we still have the same number of experienced analysts ? • Relating to measurements of metrics: e.g. In the second increment we did 20 knowledge models in six weeks. Size Productivity Characteristics Knowledge service / taxonomy Application architecture, pattern, knowledge domain, teamexperience, projectmonitoring, products, business functions, Avalability of domain knowledge registrations Metrics Number & size core taxonomies Number of knowledge models / depth of norms, principles and concepts per core taxonomie, properties, activities, atribuutsets historical metrics, project WBS Derived metrics Number of knowledge models / Number of hours / knowledge model concepts or concept 13

  16. 16. • Be Informed estimation general• Zooming in on fpa
  17. 17. “ FPA is an implementation independent measure of the functional size. So: why would you need a Be Informed-specific guideline? ” 17
  18. 18. Model = Documentation = Application• Counting or estimating fp’s must indeed be performed implementation independent;• The system’s design should be used as input;• With model based development the design artifacts can differ greatly from what the standard NESMA guideline expects;• This is also the case with Be Informed designs. 18
  19. 19. Traditional design elements versus model• Online functions • Events, case• Selection lists screens, case tabs• Reports • Knowledge• Etc. instruments • Selection lists • Reports EI EO EQ EI EO EQ • Etc. ILF ILF EIF EIF External data Internal External data Internal data model, case model data model model definitions, core taxonomies
  20. 20. NESMA prescribed Rationale• Structure model • Identify data files• Data model identifying • Determine complexity of data files record types and data element types• Indication of the information • Distinguish between ILF and EIF system maintaining the data• Behavioral model of the system • Identify user transactions• Detailed description of the flow of • Determine complexity of user data element types and controls transactions
  21. 21. NESMA prescribed Be Informed provided• Identify data files • Case model and case meta model Knowledge model Datastores Service interfaces• Determine complexity of • n/a data files• Distinguish between ILF and EIF • Case (meta) model: ILF Knowledge models and interfaces: EIF Datastores: can be both (mostly ILF)• Identify user transactions • Events: EI, EO or both Selection lists, reports and documents: extra EO Case tabs and case screens are complex meta functions: EO• Determine complexity of user • n/a transactions
  22. 22. “ Why count knowledge models as data files? ” 22
  23. 23. • The standard guideline assumes that a system’s functionality can be described entirely in the form of functions and files;• With Be Informed a system’s functionality is described in the form of functions, files and taxonomies;• There is a parallel between the structure of data and the structure of Be Informed knowledge models;• Data has a principal structure that is expressed in entities;• Be Informed knowledge models have a principal structure that is expressed in taxonomies. 23
  24. 24. Be Informed function point analysis• Certified guideline• Accepted method in Dutch Government domain• Good method to determine size of application / solution• Scope creep detected by recalculation 24

  27. 27. Sizing related to productivityWide spread of productivity due to:• Productivity is measured from ‘design to acceptance’ Be Informed is direct model driven: there is no real distinction between design and build. The biggest effort however is in the design and not in the build.• Productivity strongly depends on the customer organization: • Maturity of requirements management; • Ability to take decisions.• The experience of the team is also an important productivity factor but this can more easily be taken into consideration 27
  28. 28. Function points for sizing Be Informed?• Good results with estimating and justifying functional size based on function points with models as design input but• FP are less relevant for estimating effort in early stages.Causes:1. Less design upfront;2. High impact of design choices on productivity and scope;3. Design itself has the most predictive value for productivity. april 2009 28
