COBI 2014 - An Empirical Evaluation of Capability Modelling using Design Rationale:

609 views

Published on

The purpose of this paper, which was presented at the Cobi 2014 workshop as full paper, is to report on the utility of a specific meta-model in terms of the design and process for defining capabilities. This investigation was carried out through the FR use case that involved capability modelling on the same application, by different designers. Each approach was documented using design rationale techniques.

  6. 6. Context-CaaS Objectives • Objective 1: To elaborate a CDD methodology and supporting methods for CaaS which is adopted by the industrial partners involved in the project and their customers. • Objective 2: To create and capture best practices for delivery of digital businesses as capability delivery patterns • Objective 3: To develop methods for capability delivery adjustment according to the changes in context. • Objective 4: To establish the CDD environment and to introduce it in business environments by industrial partners. • Objective 5: To validate the capability design and delivery methodology in at least three industrial use cases, to implement capability delivery applications for these industrial cases and to test ability to adjust capability delivery to changing context in real life situations. • Objective 6: To prepare the methodology for successful industrial and academic dissemination, exploitation and uptake 7/29/2014 6
  7. 7. Context-FR’s role 7/29/2014 7 FreshTL provides the CaaS capabilities to the Enterprises The enterprises are the clients According to their requirements, the CaaS capabilities will be formed Capabilities exist in those companies and not known a-priori by FR The use cases are owned by different companies
  8. 8. Capability meta-model (1) Early version of the CaaS framework The focus of the meta-model (core components): representation of Goals Processes realizing Goals using required Resources Capability Context KPIs (measure the achievements of goals) Capability formulates the requirements for the ability of accomplishing a Goal, realized by applying a solution described by a capability delivery Pattern. This realization requires certain business Processes, Process Variants and Resources, such as infrastructure or IT components. 7/29/2014 8

Use cases The Shipping Company Use Case To integrate Shipping Expertise, modern Management principles and experience gained from existing implementations into flexible and user-friendly Software. Specific focus: Compliance of every shipping company with medical regulations. Investment promoters Use Case Help investors capitalize on their investments by striving for excellence with their investment options and offering the best customer service Specific focus: Automate a process. 7/29/2014 10

  19. 19. Observations-Treatment of concepts 7/29/2014 19 Modeler 1 Modeler 2 Capability Context Goal Variability Similar approaches in defining capability resulted in quite different definitions. For both researchers context is directly related to capability. The two modellers derived two slightly different context definitions Despite the difference in the priority given, goals were defined in the same way from both modellers. Different rationales regarding use case’s variability affected the context definition. Variability may be considered in the meta model, as related both to context and processes.
  20. 20. Observations-Approach to the process of modelling 7/29/2014 20 Modeler 1 Modeler 2Method guidance Validating model quality Both modellers were troubled about how to start due to lack of documentation. Different method guidance between modellers finally resulted in different instantiations. Lack of ontological definition leads to alternative approaches.
  21. 21. Observations 7/29/2014 21 Capability Context Key factors Need for ontological & formal definition of capability The final models are not capability centric after all Need for clear guidance regarding phases , inputs , outputs and constraints Further elaboration of the different modelling approaches
