Elements

Motivation

Stakeholder

• role
• team
• organisation
• group

Driver

• what motivate to make changes
• source of influence
• internal or external condition
  Examples:
  • Costs
  • GDPR
  • Market Share
  • Re-organization
  • Profitability

Assessment

• outcome of the evaluation of the driver
• result of analysis of the driver Examples:
  • Costs are too high
  • Order Process has flaws
  • Customers complain about the helpdesk

Goal

end state that stakeholder intend to achieve
common/general expression with: "increase", "improve", "reduce", "easier" Examples:

• Process automation
• Efficient customer service
• Increase revenue
• Occupy high place in ranking system
• Improve profit

Outcome

Realise/Implementation of the goal (in most cases),
that is going to be achieved.
Unambiguously specify the end result - measurable result. Influence on the Goal can be positive and Negative.
Difference between goals and outcomes: not all outcomes lead to the intended results. Examples:

• Robots instead of people
• Customer satisfaction increased in 15%
• revenue should be at least 12% per year
• occupy at least 3-rd place in ranking system
• increase profit by 10%

Value

represent benefit, gain, advantage, artefact (phisycal or virtual!) Examples:

• Human Capital
• Price
• Partnership
• Brand

Requirement, Principle, Constraint

Realise/Implementation of the Outcome - demands/limitations of the implementation.

Types:

• Functional Requirements (FR == UseCases) ( "Shift"==FR + nFR? )
  • functional

    content of input/output/intermittent information

  • behavioural

    internal states of the system/sub-systems

  • data

    structure of input/output information

• Non Functional Requirements ( Quality Attributes ) ( "Lift" == nFR )
  • performance
  • security
  • reliability
  • usability
  • maintainability
  • portability

Sources:

• Stakeholders
• Documents
• Existing system/application

Strategy

Implementation and Migration

• Research - create notes
• Coherence - use/update notes ( a bit create new )
• Details - use notes ( a bit update )
  after "Details" you can start from the beginning but on another level

• Metamodel
• Aspects
• Layers

Archimate extensions

Archimate to SVG export improvement.

Update destination SVG with all links from documentation properties ( also add popup hints to elements).
