In any large complex organisation where information is being passed there tends to be a huge amount of friction. The information producer structures and shapes the information in a way that suits there work practice and tends to ignore the information consumers needs. This I believe happens as the producer is creating information for their own use and as part of their own work. The resulting informational artifact is neither fish nor fowl and tends to be bloated and filled with irrelevancies. The problem is more pronounced as at the edges of domains where expectations of counterparts knowledge and expertise are challenged. ASUs are particularly helpful for domain-bridging.
Guidelines for good ASUs
To be a good ASU you should conform to the following guidelines.
- Can be co-created with relevant stakeholders including the information consumers in a 1-on-1 or workshop format
- Is simple enough to be captured on a single page (A5, A4, A3 or large format A0 in the case of a workshop)
- Is clear about it’s limitations i.e. what opinions does it have, what limitations does it impose
- Is understandable to (appropriate level of detail, appropriate language use) and useful to the information consumer(s)
- Has clear usage guidelines e.g. how do I use, how do I know when I’m done, what questions should I ask etc etc
There are any number of existing examples that could be used as examples to illustrate how ASUs work e.g. Business Model Canvas, Customer Journey Maps, Empathy Maps etc etc. I’m assuming if you are reading this that these are familiar to you and need no explanation. So I’ll introduce a new model that I’m playing with.
ASU 1: Service Interface Design Canvas
First off YAC (yet another canvas) really. I think that we are missing some useful ones. I’ve been playing around with this canvas and sharing it with colleagues and IASA training participants over the past few months. I haven’t gotten around to writing up and releasing so this is the abridged version.
Purpose: Design a Service Interface
Use: Everyone seems to be designing APIs these days so think of it in terms of designing an API. This is an ASU for API designers and API consumers (business & development consumers). It follows the conventions of Business Model Canvas with the Customer (consumer) on the left-hand-side, front-stage and back-stage.
Audience: API Developers, Business Architects, API Consumers (business), API consumers (developers)
- S1: Intra-organisation API development
- S2: Inter-organisation API development (partners/customers)
- S3: Platform Business Model Design (consumers, producers, partners)
- S4: Industr
y Service Specification e.g. BIAN
Warning(s): This is V0.1 and the bottom left hand corner is currently a dumping ground for stuff. As it’s an early version it complies with most of the guidelines except the clear usage, but that’s experimental anyway at this point.
I believe that this is the way forward, each conversation and exchange we have as architects guided and supported by ASUs.
- ASUs guide are the product of a conversation and information exchange
- ASUs are useful to the producer and the consumer of the ASU to crystalise understanding
- ASUs are there already but we are probably missing a few
More ASUs to come.
