GERAM overview by louw labuschagne

  1. 1. • Acquired by HWA in 2006 • Toaster assembly line • “House brand” manufacturer for clients • Original business • Industrial strength blender assembly line • Premium brand blender assembly line planned • New business unit started in 2009 • In-house appliance repairs • Joint venture with Phoenix Distribution • Outsourced warehousing • Distribution to major retail chains across South Africa
  2. 2. • Acquired by HWA in 2006 • Toaster assembly line • “House brand” manufacturer for clients Continues Improvement Greenfield installation Reengineering Supply chain integration Reorganisation • New business unit started in 2009 • In-house appliance repairs • Original business • Industrial strength blender assembly line • Premium brand blender assembly line planned enterprise engineering and enterprise integration • Joint venture with Phoenix Distribution • Outsourced warehousing • Distribution to major retail chains across South Africa
  3. 3. • Enterprise Architecture – Enterprise Architecture is the continuous practice of describing the essential elements of a socio-technical organization, their relationships to each other and to the environment, in order to understand complexity and manage change. http://hufee.meraka.org.za/Hufeesite/collaborations/earf • Enterprise Integration – Enterprise Integration is about breaking down organisational barriers and improving interoperability to create synergy within the enterprise to operate more efficiently and adaptively. • Enterprise Engineering GERAM V1.6.3, IFIP-IFAC Task Force, 1999 – Enterprise Engineering is the collection of those tools and methods which one can use to design and continually maintain an integrated state of the enterprise. GERAM V1.6.3, IFIP-IFAC Task Force, 1999
  4. 4. EMLs Utilise EEM Employs GERA Implemented in PEMs Support EETs Support GEMCs Used to build EMs EMOs Used to implement EOS GERAM is about those methods, models and tools which are needed to build and maintain the integrated enterprise, be it a part of an enterprise, a single enterprise or a network of enterprises
  5. 5. Enterprise Modelling Languages EMLs Utilise EEM PEMs EETs Support Used to build Enterprise Modules Support (Particular) Enterprise Models Used to implement (Particular) Enterprise Operational Systems EOS GEMCs Generic Enterprise Modelling Concepts Enterprise Engineering Tools EMs EMOs GERA Enterprise Engineering Methodology Implemented in Partial Enterprise Models Employs Generic Enterprise Reference Architecture GERAM is about those methods, models and tools which are needed to build and maintain the integrated enterprise, be it a part of an enterprise, a single enterprise or a network of enterprises
  6. 6. Industrial Engineering Control Engineering Management Science Change Process Information & Communication Technology
  7. 7. EMLs Human Concepts Utilise EEM Employs GERA Process Concepts Technology Concepts Implemented in PEMs Enterprise Engineering Tool Support EETs Used to build EMs EMOs Used to implement EOS Support GEMCs GERAM is about those methods, models and tools which are needed to build and maintain the integrated enterprise, be it a part of an enterprise, a single enterprise or a network of enterprises
  8. 8. • Human oriented concepts • Process oriented concepts • Technology oriented concepts • GERA Views
  9. 9. • Roles & Responsibilities – Single person more than 1 role – Responsibilities must be carried out concurrently and cohesively while reporting to different people using non-aligned control procedures • Need to capture constructs that promote the use of knowledge (possessed by humans) in the form of reusable enterprise models e.g. – Roles of individuals and groups – Organisational structures and constraints that are applied to co-ordinate the roles defined including delegation,reporting procedures, etc. – The capabilities and qualities of people However sophisticated and integrated an enterprise can be, humans will always make the final decision.
  10. 10. • Describe the processes in the enterprise – Functionality (what needs to be done) – Behaviour (sequence in which things are actually done) • The process-oriented concepts defined in GERA – Enterprise entity life-cycle – Life history – Enterprise entity types
  11. 11. Life-cycle Phases Enterprise Engineering Project Identification Enterprise Engineering Project Continuous improvement Project Concept Requirements Reengineering Preliminary Design Detailed Design Implementation Operation Decommission Greenfield installation Continues Improvement Time Decommissioning Project
