Roadmaps vs Architectures (View in Weblogs)

How do you develop a Roadmap for a broad-ranging community, encompassing several service-oriented architectures? Here are some ideas.

I'm currently engaged in a project, with colleagues at the CSIRO, to develop a software roadmap.

The specific roadmap we're producing involves much proprietary IP and so can't be published at this time. However, I found a dearth of material on how to produce such a roadmap and so have put together some ideas, which I am allowed to publish.

The main RoadmapDevelopment twiki page contains diagrams and people signing up to be members of that twiki can comment on there.

At the risk of subverting the page itself, I'll include a bit of content here.

Roadmap as a Collection of Assets

(I am tempted to use the word Artefacts instead of Assets but maybe Assets best-represents things which may have existed before the roadmap development activity started)

Instead of a relatively static document, consider a roadmap as a collection of relatively small assets which can be retrieved and presented in various ways.

There would be narrative sections weaving some of these assets together, including tables that might reference and summarise many more of them.

To be able to do such varied grouping, assets need identifying as being linked. This might be explicit or implicit (eg: identifying a particular stakeholder as being linked to anything with Security implications).

Another way of putting this is to say, a roadmap is chock-full of relationships.

Ways to Index or Group Assets

Depending on your role, personality or immediate question to ask, you might want to see things by
  • RM-ODP Viewpoint, eg Technical
  • Domain
  • Persona
  • Requirement
  • Schema
  • more specialised concern, eg: Security
  • Funding body or agreement
  • Stakeholder

Typical Sequences

I'm using the term Sequence here rather than Timeline because these are not necessarily temporal.
  • Temporal - planned timeline
  • Temporal - actual delivered timeline
  • Conceptual Roadmap - the "spatial" analogy, representing some order based on how things appear between two points
  • Dependency:
    • technical, as in A can't function without B
    • social or project-planning
  • Narrative - when we use use cases or stories to describe a situation being covered by the roadmap, all the things mentioned in that narrative can be summarised in the order of the narrative.
