In this design science research, we (Eero Hosiaisluoma, Katja Penttinen, Juha Mustonen, Jukka Heikkilä) propose integrating Enterprise Architecture (EA) into organisation’s development work. We call this method Lean EA Development (LEAD) – also known as 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 CIO requested to completely […]

See the reference implementation of the Lean Enterprise Architecture Framework (LEAF), that is created with Sparx EA -tool. The Sparx EA model is published as HTML, and can be accessed via this: 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 the LEAF is shown […]
Introduction The Lean Enterprise Architecture Framework (LEAF) is a tool- and modelling supported part of the Lean Enterprise Architecture Development (LEAD) approach (link). The LEAD (aka LeanEA) approach consists of operating model, framework, and methods such as Goal-Driven Approach (GDA), Service-Driven Approach (SDA) and Layered Approach. The LEAD Operating Model organizes enterprise’s capabilities around a value delivery chain, analogous to BizDevOps -approach. The LEAF is the core enabler of the LEAD method. The Lean Enterprise Architecture Framework (LEAF) The Lean Enterprise Architecture Framework (LEAF) can be used for visualization of overall aspects from ideas to production. The idea behind this LEAF is to manage […]
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 […]
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 […]
