| − | == Steps ==
| |
| − | | |
| − | The steps (see bullet points) for doing that are:
| |
| − | | |
| − | # Describe the processes and platforms (done in the [[Architecture#Current Architecture|current architecture]])
| |
| − | # Remove platform borders keeping processes and objects
| |
| − | # Analysis of the services based on vision, governance and principles
| |
| − | # Aggregation of the found limitations
| |
| − | # Description of gaps (based on found limitations)
| |
| − | # Align services towards future architecture

| − | | |
| − | == Perspectives and links to Processes, Objects, Limitations and Capabilities ==
| |
| − | | |
| − | Each perspective is assigned to a process and contains the process steps taken out of one of the systems currently covering this perspective. In the UML model the perspectives are described in detail. The following picture shows what can be found for each perspective.

| − | | |
| − | Non-functional requirements describe additional requirements besides those derived from business objects and workflows
| |
| − | | |
| − | == Basic Principles ==
| |
| − | | |
| − | The following basic principles can help to find non-functional requirements:
| |
| − | | |
| − | * Authentication and Security
| |
| − | * Small-Player Access to Services
| |
| − | * Traceability
| |
| − | * API Management
| |
| − | * Testing and Integration
| |
| − | * Service Behaviour
| |
| − | * Security and Redundancy
| |
| − | | |
| − | Non functional requirements were analysed together with the limitations and capabilities were defined, that on the one hand solve existing limitations but on the other hand also cover non-functional requirements.

| − | = Limitations =
| |
| − | | |
| − | When talking about limitations, we are in the '''World of Problems'''.
| |
| − | | |
| − | Based on the description of the current systems with its [[Architecture#Business Objects|business objects]] and [[Architecture#Workflows|workflows]] the limitations of todays systems can be analysed by making use of the [[Architecture#Perspectives|perspectives]].
| |
| − | | |
| − | == Methodology ==
| |
| − | | |
| − | # Limitations are identified in workshops based on the perspectives
| |
| − | # Limitations found are documented in a spreadsheet and in the UML model
| |
| − | # in order to cluster the limitations
| |
| − | ## duplicates are eliminated (in the spreadsheet)
| |
| − | ## dependencies between limitations are documented in the UML model
| |
| − | # then the limitations are grouped into limitation groups in the UML model
| |
| − | # for each of the groups the benefits and impacts are defined
| |
| − | # all the groups are categorized in low, medium and high priorities
| |
| − | | |
| − | == Criteria ==
| |
| − | | |
| − | The criteria to select potential limitations are:
| |
| − | | |
| − | * Constitutional Governance
| |
| − | * Data Governance
| |
| − | * Service Shaping
| |
| − | * Accessibility
| |
| − | * Integration
| |
| − | * Master Data
| |
| − | * Identifiers
| |
| − | | |
| − | == Priorities ==

| − | === Ranking ===
| |
| − | | |
| − | Based on sum of the scores of each criteria, multiplied with the weighting of the criteria an individual priority of each limitation results
| |
| − | | |
| − |
| |
| − | | |
| − | Priority = (Score PA * Weight PA) + (Score L * Weight L) +<br />
| |
| − | (Score D * Weight D) + (Score V * Weight V) +<br />
| |
| − | (Score E * Weight E)
| |
| − | | |
| − |
| |
| − | | |
| − | The priority of each limitation varies within the range of 1 and 10.
| |
| − | | |
| − | The higher the priority value the higher the ranking of a limitation.
| |
| − | | |
| − | === SAFe Ranking ===
| |
| − | | |
| − | The limitations were ranked additionally according to the SAFe Methodology (Scaled Agile Framework) in order to analyse the limitations in a longer planning horizon and set priorities accordingly.
| |
| − | | |
| − | The lower the SAFe for a limitation, the higher is the priority to act.
| |
| − | | |
| − |
| |
| − | | |
| − | SAFe = Score E / Score VA / Score PA
| |
| − | | |
| − | * the higher the effort, the higer the SAFe, meaning, the lower is the priority to act.
| |
| − | * the higher the value added and/or the problem are, the lower is the SAFe, meaning, the higher is the priority to act.
| |
| − | | |
| − | == Conclusion ==
| |
| − | | |
| − | Based on the above described methodology the following 26 highly ranked limitations were found
