Combining Design Thinking and Architectural ThinkingThe Lean Enterprise Architecture Toolkit can be used in combination with the Human Centered Innovation Approach as defined by the SAP AppHaus. While theLean Enterprise Architecture Toolkit applies an engineering mindset to understand, describe, and solve a business problem, the Human Centered InnovationApproach applies a user-centric view to the business problem with the help of Design Thinking. While Design Thinking focuses on the alignment of users andbusiness, the Architectural Thinking with the toolkit focuses on the alignment of business and IT.ExplorePhasesDesignThinkingExplore innovationopportunities:§ Cluster of innovationopportunities§ Prioritize and selectinnovation opportunity§ Use-case definition§ Stakeholder mapDesignDiscoverGain commonunderstanding of currentenvironment and needs viaconsumer, employee, andmarket research:§ First insights to overcomethe challenges§ Research summary§ As-is user journeyDeliverDesign and create aprototype of the solution:§ Storyboard for selectedsolution idea§ Low-Fidelity sketches§ Clickable prototype§ Visual design§ User storiesDevelop and deliver thetailored business andtechnical solution forproductive use:§ Deliver productive solution§ Customer acceptancereportUse-Case Blueprint DiagramArchitecturalThinking WorkProductsUnderstand yourcompany’s business goalsand strategic drivers:§ Strategy Map§ Stakeholder Map§ Statement of ArchitectureWorkDomains 2021 SAP SE or an SAP affiliate company.

Overview of the content of the Lean EA ToolkitThe Lean Enterprise Architecture Toolkit is comprised of 15 work products: 7 work products describe the business domain, and 8 work productsdescribe the technical domain. Work products from the business domain are used to communicate with stakeholders from the businessdepartments as well as business executives and business management. Work products from the technical domain are predominantly used tocommunicate with stakeholders from IT. Each work product of the toolkit is described by a template, an example showing the adoption of thetemplate, and a brief guide for creating the work product based on its template.Generally, the work products of the toolkit are applied in a defined sequence. The reason for this is, that results from one work product serve asinput for the creation of other work products.Pre-requisite to apply the toolkit:Use-Case (request for architectural work)Use-CaseBlueprintDiagramStart ureStakeholderMatrixStatement gramConceptualData DiagramArchitecturalDecisionsBusiness Architecture Domain 2021 SAP SE or an SAP affiliate company.

Start options for using the Lean EA ToolkitDepending on the driver for architectural work, the sequence of using the templates of the toolkit can be adapted, respectively. Considering abusiness department that issues a request of architectural work, the Strategy Map or Statement of Architecture Work might be one of the first workproducts being created. In case the IT department would like to discover the business value of using a specific technology, the Solution Concept orBaseline Solution Architecture might be the work products to start with the architecture development.Use-CaseBlueprintDiagramStart option BusinessStart option takeholderMatrixStatement gramConceptualData DiagramArchitecturalDecisionsBusiness Architecture Domain 2021 SAP SE or an SAP affiliate company.

Activities when using the Lean EA ToolkitUsing the Lean EA Toolkit involves different activities for the creation of the work products. Each work product offers a different view onthe architecture.
