ABOUT SHAWN MAJESKI
Executive value proposition: My value is through the lens of a Senior Enterprise Architect (Lead, Head of, etc.) by addressing complex challenges through pragmatic decision-making with a focus on “what good looks like” across strategy, execution, and governance. My approach emphasizes aligning business vision, operating models, and technology ecosystems through structured architectural thinking. I work closely with executive leadership and cross-functional stakeholders to align priorities, define target-state architectures, balance innovation, risk, and operational excellence.Architecture Leadership: As a senior technology and enterprise architecture leader with more than 25 years of experience spanning enterprise IT strategy, business architecture, operating models, and solution architecture across complex organizational environments, I have directed initiatives with CAPEX and OPEX budgets ranging from £5 million to £150 million, consistently aligning investments with enterprise architecture principles and outcomes. My background includes:• Designing and governing large-scale, enterprise-wide integrations and transformation programmes• Major contributions to RFP processes, vendor selection, and commercial negotiations• Defining outcome-driven delivery models that address risk, security, costs, legal and regulatory frameworksI operate comfortably at board and executive-level governance with hands-on engagement in areas of strategic leadership, practical execution to modernize technology landscapes, rationalize portfolios, and align architecture decisions with business strategy.Operational & Process Involvement: Recognized for designing and leading enterprise governance structures that ensure architectural integrity, transparency, and value realization across technology portfolios. I have established and chaired Architecture Review Boards (ARB’s) and enterprise governance forums that enforce standards, reduce duplication, and mitigate risk arising from fragmented or non-compliant development initiatives. My typical involvement is ensuring enterprise roadmaps, capability models, and reference architectures are aligned between business and technology.Accountable & when to engage: Most frequently engaged where organizations require senior-level leadership across enterprise architecture domains, multi-tower technology environments, and hybrid infrastructures. In practice, this breadth of accountability is required in most modern organisations—where technology, business operations, and customer experience are deeply interconnected.
