No Single (Design Solution) Size Fits All (Design Problems)!
      g

                       A set of reference solutions should each
                        address a class of design problems
                        (e.g. quadratic vs rectangual vs round roofs)
                       Reference solutions should be adaptable to
                        specific problems within that class
                        (e.g. building size, height)
                       Still all/many solutions might have certain
                        common elements/components
                       We designate
                         – such design solutions “situational”
                         – dimensions along which problem
                           classes are defined “design factors”
                            (roof shape. building height)
                                  shape
                         – resulting problem classes “situations”
                         – reusable solution components

Proposed Situational Method Engineering Procedure
 Phase 1: Analysis of existing design solutions
   – Goal: Understand artefact mutability within design problem class
   – Input: Set of design solutions; Potential design factors
   – Output: Relevant design factors; Design situations (incl. context
     types, project types)
   – St
     Steps 1-7
             17

 Phase 2: Derivation of situational design method
                                         g
   – Goal: Provide situated method support for relevant design situations
   – Input: Relevant design factors; Design situations (
       p                 g         ;     g             (incl. context types,
                                                                       yp ,
     project types)
   – Output: Design method fragments; Configuration rules (fragment-
     situation assignment)
   – Steps 8-11

                                                                  © Apr-11, IWI-HSG

Phase 1 (Analysis)
Steps 1-3
      13

1.
1 Delineate the design problem class (= EAM)
   Find appropriate definitions, envision the solution artifact and
   develop an idea about design goals.

2. Literature analysis: Identify potential contingency factors for
   EAM (= relevant stakeholders/concerns, scope, competences,
         (  l    t t k h ld /                         t
   etc.)

3. Conduct a field study in order to analyze design problems of
   that class in practice. As a result, the list of potential
   contingency factor candidates is reduced to a smaller set of
   relevant “design factors”. Design factors might be aggregates of
   several contingency factors that need to be semantically
   interpreted.

Potential EAM Contingency Factors

 Understanding of EAM
 Organisational embedding of EAM
   – Organisational units responsible / involved in EAM
   – Stakeholders and users of EAM
   – Continuous implementation of EAM
 EAM utilization and functionalities
   – EAM ser ices and their cons mption
         services           consumption
   – EAM functions
 EAM planning

Phase 1 (Analysis)
Steps 4-7

4. The design problem class is redefined by specifying value ranges
   for the design factors. This means that “outliers” are ignored from
                  factors                     outliers
   further analysis in order to create homogeneous problem sets and
   subsets.
5. Those field study data of observations which still belong to the
   redefined design problem class, are used to calculate ultrametric
   distances between specific design solutions. Th calculation i
   di          b               ifi d i         l i       The l l i is
   based on certain ‘similarity’ metrics– usually the Euclidian distance
   with regard to the observed values of design factors
                                                    factors.
6. A useful level of solution generality is determined. Usually
   clustering errors related to the number of clusters are used for this
   analysis.
7. Using the desired solution g

8. By linking back analysis results to the characteristics of the
   underlying design problem descriptions, design f   factors ( result
                                                              (=
   of principal component analysis) and design situations (= result
   of agglomerative cluster analysis) of the design problem class
   are interpreted semantically.
9.
9 Those combinations of design (problem) situations and 1 or 2
   design factors are identified where the selected design factors
   represent best an elementary problem solution fragment.
10.By linking desired properties to design factors, ideal problem
   solutions are related to the n-dimensional system. If many
                                                    y             y
   observations in the data set have already reached such desired
   state(s), there might be even one (rarely more) “design
   situation(s)” where the problem has already been solved – i.e.
   there might have been cluster(s) identified that represent(s) ideal
   problem solutions.

  • 2. No Single (Design Solution) Size Fits All (Design Problems)! g  A set of reference solutions should each address a class of design problems (e.g. quadratic vs rectangual vs round roofs)  Reference solutions should be adaptable to specific problems within that class (e.g. building size, height)  Still all/many solutions might have certain common elements/components  We designate – such design solutions “situational” – dimensions along which problem classes are defined “design factors” (roof shape. building height) shape – resulting problem classes “situations” – reusable solution components “fragments” © Apr-11, IWI-HSG Slide 2
  • 3. When Using Euclidian Metrics, Ultrametric Distances can be Calculated that Allow to Arrange Concrete & Generic Solutions in a Tree Diagram Design Solution genericity Selected range of design problems © Apr-11, IWI-HSG Slide 3
  • 4. Design Dimensions Better Help to Understand the Mutability of (Concrete & Generic) Solutions Solutions
 Design Dimension 1: Shape of roof two sided four sided round Design Dimension 2: Height of low l high hi h building © Apr-11, IWI-HSG Slide 4
  • 5. Using Design Theories (if Available), Solution Fragments are Constructed Along Design Dimensions DT1: combination if t wide too id DT2: Double oub e roof © Apr-11, IWI-HSG Slide 5
  • 6. Proposed Situational Method Engineering Procedure  Phase 1: Analysis of existing design solutions – Goal: Understand artefact mutability within design problem class – Input: Set of design solutions; Potential design factors – Output: Relevant design factors; Design situations (incl. context types, project types) – St Steps 1-7 17  Phase 2: Derivation of situational design method g – Goal: Provide situated method support for relevant design situations – Input: Relevant design factors; Design situations ( p g ; g (incl. context types, yp , project types) – Output: Design method fragments; Configuration rules (fragment- situation assignment) – Steps 8-11 © Apr-11, IWI-HSG Slide 6
  • 7. Phase 1 (Analysis) Steps 1-3 13 1. 1 Delineate the design problem class (= EAM) Find appropriate definitions, envision the solution artifact and develop an idea about design goals. 2. Literature analysis: Identify potential contingency factors for EAM (= relevant stakeholders/concerns, scope, competences, ( l t t k h ld / t etc.) 3. Conduct a field study in order to analyze design problems of that class in practice. As a result, the list of potential contingency factor candidates is reduced to a smaller set of relevant “design factors”. Design factors might be aggregates of several contingency factors that need to be semantically interpreted. © Apr-11, IWI-HSG Slide 7
  • 8. Potential EAM Contingency Factors  Understanding of EAM  Organisational embedding of EAM – Organisational units responsible / involved in EAM – Stakeholders and users of EAM – Continuous implementation of EAM  EAM utilization and functionalities – EAM ser ices and their cons mption services consumption – EAM functions  EAM planning l i 54 Questions © Apr-11, IWI-HSG Slide 8

  • 11. Phase 1 (Analysis) Steps 4-7 47 4. The design problem class is redefined by specifying value ranges for the design factors. This means that “outliers” are ignored from factors outliers further analysis in order to create homogeneous problem sets and subsets. 5. Those field study data of observations which still belong to the redefined design problem class, are used to calculate ultrametric distances between specific design solutions. Th calculation i di b ifi d i l i The l l i is based on certain ‘similarity’ metrics– usually the Euclidian distance with regard to the observed values of design factors factors. 6. A useful level of solution generality is determined. Usually clustering errors related to the number of clusters are used for this analysis. 7. Using the desired solution g g generality, the resulting design y, g g situations are specified. The situations should not only be specified formally (by value ranges of the design factors), but also should b i t h ld be interpreted semantically (“design problem t t d ti ll (“d i bl types”). ”) © Apr-11, IWI-HSG Slide 11

  • 19. Phase 2 (Method Derivation) Steps 8-10 8 10 8. By linking back analysis results to the characteristics of the underlying design problem descriptions, design f factors ( result (= of principal component analysis) and design situations (= result of agglomerative cluster analysis) of the design problem class are interpreted semantically. 9. 9 Those combinations of design (problem) situations and 1 or 2 design factors are identified where the selected design factors represent best an elementary problem solution fragment. 10.By linking desired properties to design factors, ideal problem solutions are related to the n-dimensional system. If many y y observations in the data set have already reached such desired state(s), there might be even one (rarely more) “design situation(s)” where the problem has already been solved – i.e. there might have been cluster(s) identified that represent(s) ideal problem solutions. bl l ti © Apr-11, IWI-HSG Slide 19
