In this design science research, we (Eero Hosiaisluoma, Katja Penttinen, Juha Mustonen, Jukka Heikkilä) propose integrating Enterprise Architecture (EA) into an organization’s development work. We call this method Lean Enterprise Architecture Development (LEAD) – also known as Lean EA (LeanEA). See the research article from the Research Gate link. Or you can get the pdf from here, link. Note! The case story is an EA success story in the public sector, but the same approach applies to private sector too. This is a story, in which EA was re-designed and integrated into an organisation’s development work in an IT department. The […]

See the reference implementation of the Lean Enterprise Architecture Framework (LEAF), which is created with Sparx EA -tool and published as HTML report. LEAF 2.2 link LEAF 2.0 link LEAF 1.0 link The LEAF can be used for linking enterprise architecture to solution architecture. High-level enterprise architecture diagrams can be modelled with ArchiMate, from which modellers (and other stakeholders) can drill-down to more detailed diagrams that can be modelled with BPMN or UML. The level-1 (the navigation landing page, the “front page”) of the LEAF is shown in the diagram below (figure 1). The level-2 (domain view) of the LEAF […]
Intro Lean EA approach supports the holistic development of an organization. Lean EA consists of value chain-based development operating model (LEAD) and integrated Enterprise Architecture (EA) practice – with the supporting framework (LEAF). The Lean EA combines management and operational development with the EA. First some basic facts: Lean EA is not focusing on EA. Lean EA is focusing on the overall business development work of an organization (incl. management, operational development and operational business). That’s the beef. A Lean way to produce services and products from idea to production. Lean EA is focusing on the outside-in view, the customer […]
1. Introduction In this digital age, Enterprise Architecture (EA) planning is more important than ever before. New computing models such as cloud, mobility, Internet of Things (IoT) and API economy have arisen, and the overall complexity of the organization’s landscape increases continuously. However, quite often conventional Enterprise Architecture Frameworks have been found too complex, too academic and cumbersome to understand. More practical and easier approach with simpler framework is needed. 1.1 The Lean Enterprise Architecture Development (LEAD) Method The Lean Enterprise Architecture Development (LEAD) method is a new style of EA approach. The LEAD consists of a) value chain-based operating model and […]
Lean & Agile Enterprise Development is based on agile and lean practices, but the main focus is on customer value add-on delivery and customer experience. All the other principles shall be derived from those. The most important principles are as follows: Customer Value add delivery above all, from which everything shall be derived from, Collaboration and co-operation throughout the organization, over teams and functions, Visibility throughout the organization, all the aims, activities, actions, ideas, development targets, to be enabled with a visualization tool (EA-tool)! There are many useful and valuable principles for lean & agile design and development, some of which are introduced […]
