Concept Canvas

Here is an example of a Concept Canvas that can be used when analyzing an idea to a concept. This concept canvas (figure below) is based on Business Model Canvas, BMC (link), Lean Canvas (link) and Opportunity Canvas (link), but this layering and positioning of the boxes is analogical to architectural layers (e.g. as described […]

Lean Enterprise Architecture Development (LEAD)

What? Value Chain Based Lean Enterprise Aware Design, Development & Operations. Drivers For Change Continuous change in the operational environment with new digital enabler technologies are driving enterprises to cultural and organizational changes. The overall development has to be organized around creating and delivering added value to customers. Organizations have to be more efficient and […]

Value Stream Modelling

Value? Value is fundamental to everything that an organization does. The primary reason that an organization exists is to provide value to one or more stakeholders. It is the foundation of a firm’s business model, which describes the rationale for how a business creates, delivers, and captures value. [Value Streams, Open Group, 2017] Value Stream? A key […]

Lean Enterprise Architecture Method For Value Chain Based Development In Public Sector

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 […]

Application Architecture Modeling With ArchiMate

Introduction Application Architecture (or Solution Architecture, SA) can be modelled with the same set of ArchiMate diagram types as other levels of architecture (Enterprise- and Domain levels). Application architecture can be modelled with a small subset of ArchiMate elements as follows: Application Component, Application Service and Application Interface. Relationships between those elements can be modelled with […]

Service-Driven Approach (SDA)

Introduction Holistic enterprise development can be supported by the Service-Driven Approach (SDA), which focuses on services (instead of projects) as primary units of  value creation, design, development and operations. The SDA combines both customer oriented (“outside-in”) and organization internal behavior and structure oriented (“inside-out”) approaches. By focusing on services, enterprise development (or an IT function) can […]

Lean EA Framework (LEAF) Sparx EA Reference Implementation

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 […]

Lean Enterprise Architecture Development (LEAD) Method – A Practical Approach

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 […]
