Maturity models are widely used for organisational self-assessment, but their value is often limited to producing a score. This paper argues that far greater value is achievable by extending models to include prioritised recommendations and action planning — and by automating the whole process to remove the friction that discourages use. Drawing on the development of a generic domain model implemented in the EVA platform, it demonstrates how a range of maturity models can be rapidly deployed, assessed, scored, and translated into actionable improvement plans with minimal custom code.
Designing an Effective Graphical Modelling Language
Graphical models are central to enterprise architecture and information systems work, yet they frequently fail to deliver value — not because the underlying analysis is wrong, but because the notations are poorly designed, mismatched to their audience, or unable to highlight what matters. This doctoral research paper sets out a programme of design science research aimed at improving visual language design and tooling, drawing on insights from human cognition, perception, semiotics, and graphic design. It introduces polymetric diagramming as a technique for making models more expressive and proposes a meta-meta model and tool architecture to support more effective visual language design and use.
