What is Holocentric Modeler
Holocentric

• a tool that captures, organizes, integrates and
  presents models, specifications and code for
  developing object-oriented software and systems.
• Integrates object-oriented methods and languages
  into a seamless development approachfrom early
  analysis and design concepts through to detailed
  class code and back again
• supports a number of popular object-oriented
  methods and notations, which cover Class, Object
  Interaction, Use Case diagrams as well as General
  Diagrams
• Incorporates the capacity to model both business
  and system design in an integrated environment

Business Process Model
Holocentric

• Identify the actors and model the business
  process
• Engage business representatives and arrange
  workshops to model with them model current
  business process, if necessary, then future
  business processes fulfilling the intent of the
  required change
• Document the internal and external users/actors
  involved in the system
• Model the business process - begin at a high
  level and gradually increase the granularity i.e
  determine the scope of the business then the
  major processing areas, then the processes within
  those areas.

The benefits of the BPM include
Holocentric

• Business sign-off and ownership of final business
  process
• Shared understanding of business process
• Emergence of products and services that support
  the users experience of the business process
• Identification and clarification of business
  rules impacting on the process
• Understanding of responsibilities and
  capabilities
• Exposure of touch points between users and the
  systems supporting the business process

Process Steps
Holocentric

• Are an extension of the UML Use Case forming the
  hub of the functional requirements and include
  the following content
• A description of the work to be carried out
  within the process step and how that piece of
  work will satisfy the needs of the stakeholders
  and fulfil the business intent
• A series of dialogues or usage scenarios
  describing the interaction between the actors
  (Human and system) within the process. This
  consists of a normal course describing the main
  success scenario and a series of alternate
  courses detailing other scenarios which may be
  either successful or unsuccessful.
• Pre and Post Conditions detailing the expected
  state of systems or other events both before and
  after the process step is executed

Modelling the Business Requirements
Holocentric
The requirements model reaches maturity through
linking artefacts to their relevant use cases as
they reach completion. The final result is a
complete section of the business process that can
be signed off by business and subsequently built
by the development team.

Benefits of a Modelling Business Requirements
Holocentric

• Functional requirements are expressed in
  Business Context with system responsibilities
  defined as a series of interactions between
  participants (Actors as Human or System) within a
  business process
• The system design is approached from both a user
  and business perspective
• The conceptual design evolves in a transparent
  and flexible manner
• Each use case consists of a build able and
  testable unit of work leading to a potentially
  iterative development process

Holocentric Artefacts
Holocentric
This diagram displays the relationships between
the artefacts included in a standard Holocentric
analysis model. External artefacts such as
screen shots are included as required using
links to the relevant object.

Benefits of using Holocentric Modeler
Holocentric

• Standardised approach to business and application
  design
• Centralised repository of project information
• Traceability from original business requirements
  to implementation of code
• Simulation of the entire Business Change which
  incorporates all products to support the users
  experience
• Approach the business and IT design from the
  users perspective
• Design artefacts (e.g. Business Rules Actors)
  can be reused and shared both within and outside
  the organisation
• Powerful scripting language allows tool
  customisation
