Now reshaping Endava for the AI-native era. 2000 Internet & distributed systems shift 2010 Digital transformation shift What has changed • AI makes some tasks faster, cheaper and easier to replicate across the market. • Buyers increasingly expect service partners to show how AI will improve delivery. What has not changed • Clients still pay for the right problems being solved, not for activity alone. • Quality, judgement and accountability remain critical. • Sector expertise still matters. Today AI-native shift 89 AI use is now mainstream. Scaled enterprise value is still uneven. The market challenge has shifted from access to AI tools to turning AI into governed business outcomes. (1) McKinsey, The State of AI: in 2025: Agents, innovation, and transformation November 2025; (2) PwC 2026 Global CEO Survey January 2026;(3) Deloitte: State of AI in the Enterprise, January 2026 (4) Fiona Czerniawsk: “AI: An identity crisis for consultants? August 19, 2025. Client expectations have moved on 74% of consulting buyers now expect firms to explain how AI will be used in delivery (4) Adoption is mainstream Penetration is still uneven Value is still unproven Governance is still immature 88% of organizations report AI use in at least one business function (1) National statistics and Central- bank analysis still show lower economy-wide adoption across the UK, EU and US business base Only 12% of CEOs say AI has delivered both cost and revenue benefits (2) Only 1 in 5 companies has mature governance for autonomous AI agents (3)Since early 2025, Endava has been embedding AI across delivery, operations and client solutions.i Endava has been reshaping itself for the AI-native era. This is a company-wide transformation spanning capability, workflows, governance, partnerships, and leadership. 10 What has changed • Redesigning workflows for hybrid human–agent delivery. • Evolving delivery discipline and ways of working. • Moving from isolated tool use to a governed system. How work flows Talent and leadership • Building next-generation talent across engineering, AI, product and domain expertise. • Reinforcing leadership for AI- native change. • Creating multidisciplinary teams that can shape and deliver faster. Who does it Governance and enablement • Embedding guardrails, metrics and traceability into delivery. • Creating clearer rules for where automation can accelerate safely. • Making assurance visible rather than retrospective. How it scales Ecosystem and innovation • Expanding strategic partnerships, including Cognition and Miro, alongside hyperscalers. • Using ventures and ecosystem routes to market where they strengthen the response. • Keeping the method adaptable as tools evolve. How it adaptsDava.Flow is one methodology of that broader shift. What it does Enhanced problem qualification Captures signals early so teams start with clearer priorities rather than assumptions. Defined scope and agent-ready work Turns intent into validated, decision-ready work that humans and agents can act on safely. Execution under guardrails Accelerates delivery while keeping quality, security, traceability and human approvals visible. Continuous learning Uses production evidence and operational signals to improve what happens next. It is a tool-agnostic, human-accountable lifecycle for moving from signal to clearer definition to controlled execution to ongoing learning. Dava.Flow TM 11 Signal Qualify what matters early. Explore Make the work decision-ready. Evolve Turn production into learning. Govern Deliver faster under guardrails.Four connected phases designed to improve clarity, speed and control. Each phase contributes one clear job and one clear commercial benefit; together they create a governed flow rather than a chain of hand-offs. Identify and qualify the right opportunities early. Why it matters: reduces noise and avoids premature commitment. 1 Signal Turn intent into clear, decision-ready and agent-ready work. 2 Why it matters: improves alignment and lowers rework before delivery starts. Explore Execute faster under explicit quality, security and approval guardrails. 3 Why it matters: increases speed while keeping accountability visible. Govern Learn from production and feed evidence back into the next cycle. 4 Why it matters: compounds improvement and keeps systems aligned over time.
