(based on many people asking what the requirements are for a tool)
People often ask me what lead us to working with the tool sets we use for enterprise architecture and business transformation (EA/BT). The following is a short background.
Obviously the overall objective is to improve an organisation's effectiveness (reduce costs, improve income/outputs, ensure regulatory compliance, build asset value etc.). This requires managed change. I had focused how to improve the quality of transitions from RHE's inception (the best people, methods and tooling). We had tried using a wide range of OTS tools (e.g. CASE, Ontology, Document management and of course Office suites) and building tools to allow us to manage this information. After many years of trying to determine how EA/BT work could be done (in a way produce sustainable value for clients) and a long term focus on methods (including frameworks) we determined the tooling was inadequate (and the tool limitations fundamentally affected the method).
In 2002 we reassessed what tools were available that could be used to support:
- business strategies: drivers, plans, markets, products/services, locations, organisations, resources, change/transitions, projects/initiatives;
- business operations: communciations, services, processes, rules, information, organisation etc;
- technology architecture: enterprise, solutions, components/systems, etc. Supporting any: styles, topology pattern, interaction models etc. And integrating detailed design models (e.g. UML, ER, BMPL/N, SOA) etc. and integrate data from other sources (e.g. CMDBs);
- business and technology alignment: relationships and dependencies between the business and technology;
- requirements (business/systems): at various levels of detail supporting an understanding of acceptance/contracts/terms and design/delivery;
- change over time: time based views of all of the above (as-is, to-be, transitional);
- change initiatives: programmes, projects (e.g. costs, risks, resources, timeframes) and business cases (e.g. benefits, fit to current environment etc.);
- manage the semantics: model any object, and relate it to any other object; for a predefined library of object we would have a predefined set of properties, methods and relationships to other objects; it would be easy to change the modelling language (objects, relationships, properties, methods, appearance, nesting etc.); and we would be able to structure the knowledge to support any framework (taxonomy e.g. Zachman, FEAR, TOGAF, eTOM, etc.) so these could be tailored to specific customers/project needs etc.)
- communicate: create visulations based on any sets of objects with the appearance, level of detail, layout, type information displayed, etc. changed to suit the audience/purpose; allow all authorised people to see the subset of the information they are interested in and annotate/revision-mark that information; allow publishing in any format e.g. office documents, images etc. and via customisable web interfaces (e.g. to support mashups etc.)
- integrate: with other sources so we could exchange data with modelling tools; databases/applications; systems tools (e.g. CMDBs); portfolio management tools; programme management tools; dedicated modellers (e.g. project plan, UML, BPM, Data/ER, SW architecture analysis tools); etc.
- easy to use and automatable: allow users to very quickly and efficient create models with very little knowledge of the tool (and very little training), to support workflows associated with maintenance and use of the knowledge.
- open and extensible: to be standards compliant and implementation technology and technical architecture agnostic. To be able extensible so it can be customised to exactly what we or a client believes is needed.
- powerful analysis and reporting: to be able produce reports (using standard reporting tools) in whatever form (visual, textual, dashboards) and type (Word, PDF, web forms etc) is required and access these reports from portals and client tools so the knowledge can be visible to all stakeholders in a way to suits there specific needs, roles at each point of interaction.
- tool to ensure the quality and currency of information: so we could automate the collection of data (where there is another source of record e.g. ERP, CMDB, etc.), to maintain policies on data (that allow data quality to be monitored/assessed), to allow easily ad-hoc updates by many users (who can do so as part of their day to day job) and proactively survey/poll users (when it is believed the data is out of date).
- secure, scaleable and accessible: to support a large number of ad-hoc users (many that will only interact with the systems for a small % of the time but all of whom have an interest or are guardians of bits of the jigsaw puzzle.
- tailored to specific purposes: solutions (based on tailored metamodels, user interfaces, system interfaces) to support specific jobs e.g. enterprise strategy or architecture; business cases and investment plans; technical architecture e.g. solution/integration/service/data/storage; or managing requirements, metadata, design, acceptance, programmes of work, security, business continuity
- sophisticated management of multiple states: as in reality large complex enterprises have many initiatives operating each of which is expected to change the current state (at different points in time) and automate the way the changes will ripple through those states.
- suited to business (and technology) orientation - so ideally one could start with the business side e.g. able to manage business drivers and requirements and solutions.
- flexible, extensible and customisable (language of modelling, user interfaces, data interfaces, datamarts, analysis and reporting) - so modelling can be done in terms/language suited to the business
- powerful visual analysis and representations (for large amounts of data, power users, and design)
- supporting a broad and diverse community of users (with suitable roles and security controls for those different groups of users)
- automated data collection
- communicating in various ways: diagrams, charting & analytics, reporting etc.
- multiple states and transitions between states
