1 Methods (AM) DOUMENT Architecture matrices and their uses It is illegal to copy, share or show this document (or other document published at without the written permission of the copyright holder

2 Matrices An architecture description includes many types of architectural entity You can catalogue the instances of each architectural entity type You can show relationships between entities in matrices ole M EP Warehouse P officer Salesman 1 st line support Fulfilment agent M EP DW/BI M EP DW/BI

3 Matrices as artefacts in a document framework Architectural entities Architecture artefacts Architecture models and languages Management documents A meta model for an architecture repository Pre-defined classifications and reference models POLDAT etc. atalogues that list architectural entities with attributes Matrices that relate architecture entities Diagrams that describe and/or relate architectural entities e.g. ArchiMate, UML, AML Deliverables, work in progress or signed off. Often contain architecture artefacts Defines architectural entities, their attributes and inter-relationships Generalised taxonomies and common design patterns

4 Examples of relationships between entities performed in Organisation supported by accesses stored in Store Org. Unit Store Organisation works at Location Location runs at Location uses Technology Technology hosted at Location Store uses Technology Technology

5 Inter-entity relationships as tables, grids or matrices Org Performs Org Org supports cru crud r Performs supports rud ru crud Performs Performs supports supports r r Org. Unit Store Location Org Org Org Loc Works at Works at Store M Loc Works at Works at Store M M Loc Works at Store store store store Tech uses Tech uses Tech uses Technology Tech uses Tech uses Tech uses

6 Matrix uses The matrices can be used for Impact/Dependency analysis Gap analysis Traceability analysis luster/affinity analysis

7 Matrix uses: impact/dependency analysis Impact analysis implies recording dependencies, so you can follow mappings to check if a change to one item causes a change to related items. M EP DW/BI M EP DW/BI DW/BI The same thing in UML EP M

8 Matrix uses: gap analysis You may want to compare a vision with reality a specification with an implemented solution a baseline with a target Target s Baseline s M Business Intelligence Baseline to be dropped Ported to new platform M Left as is esourcing Dropped (accidentally)? Target to be introduced New (bought or built?)

9 Matrix uses: traceability analysis Traceability records usually cross-refer items in a requirements configuration to items in a solution configuration. Solution items equirements Business Intelligence Sales mobile device M equirements that have no solution Faster Ordering Satisfied by emote Working Satisfied by Better Forecasts Satisfied by Lower Sale ost No solution Solution items that have no requirement No requirement Note that in test-driven development you map requirements to test cases test cases to solution components

10 Matrix uses: cluster analysis This means mapping data to activity This can be done at different levels, and in different ways. Activity ustomer Order Delivery Invoice Delivery Sales eporting Payment eport Use the NW corner method to sort rows and columns of a useto-data matrix This suggests the boundaries of data stores Activity ustomer Order Delivery Invoice Payment eport Sales Delivery eporting

11 Matrix uses: summary Impact/Dependency analysis To find the effects of a change Gap analysis To find potentially missing items Traceability analysis To check deliverables meet goals and solutions solve problems. luster/affinity analysis To group closely-coupled items into encapsulated components
