Common Mistakes to Avoid

Common failures across enterprise architecture service engagements come from choosing delivery patterns that do not match governance maturity, decision cadence, or the need to convert architecture into implementation work.

  • Selecting a governance-heavy approach when lightweight architecture artifacts are required

    Deloitte, PwC, and KPMG can deliver strong governance and assurance, but their delivery can become heavy for organizations needing lightweight architecture artifacts. Accenture can also feel slower for rapid ideation because enterprise architecture governance is embedded in structured decision frameworks.

  • Letting internal ownership and decision cadence stall architecture stability

    IBM Consulting and NTT DATA both tie program outcomes to client governance and intake quality, so weak internal decision cadence reduces architecture output stability. EPAM Systems also depends on strong client ownership of decision making to keep target-state migrations on track.

  • Assuming architecture design will automatically translate into implementable delivery

    Deloitte, Capgemini, and PwC deliver strong architecture governance and roadmaps, but teams still need clear internal translation to delivery execution. Tata Consultancy Services, EPAM Systems, and Globant reduce this risk by pairing architecture governance with engineering delivery and implementable solution blueprints.

  • Choosing an overly broad engagement scope without clear execution boundaries

    KPMG, Capgemini, and NTT DATA can broaden scope through comprehensive governance and transformation planning, which can increase complexity when the change is narrowly scoped.
