Enterprise technology implementation has substantial published research behind it. The patterns that distinguish successful implementations from failures are well-documented. Despite this, implementation failure rates remain high — credible estimates suggest 30-50% of major enterprise implementations fail to achieve stated objectives.
This article presents a methodology for enterprise technology implementation grounded in research on deployment outcomes.
The factors that determine implementation outcomes
Research consistently identifies several factors as substantially affecting implementation outcomes:
1. Executive sponsorship. The depth and durability of executive commitment to the implementation. Implementations without sustained executive sponsorship rarely succeed regardless of other factors.
2. Change management capacity. The organizational ability to absorb the operational changes the implementation requires. Underweighted change management is the most common cause of implementation failure.
3. Scope discipline. The ability to maintain implementation scope against the inevitable expansion pressure. Scope expansion is the most common cause of implementation overruns.
4. Implementation team capability. The skill and experience of the team executing the implementation. Capability gaps are difficult to compensate for during execution.
5. Vendor and partner quality. The capability of external vendors and implementation partners. External capability gaps amplify internal capability gaps.
6. User adoption planning. The systematic preparation for actual use of the system after deployment. Implementations that achieve technical deployment without user adoption fail to deliver value.
Each factor warrants explicit attention in implementation methodology.
The executive sponsorship requirement
Executive sponsorship is the foundation of successful implementation. The sponsorship requirements:
- Specific named executive accountable for implementation outcomes
- Direct involvement in major decision points
- Visible advocacy for the implementation across the organization
- Resource allocation authority sufficient to address emerging challenges
- Sustained engagement throughout the implementation timeline
Sponsorship failures typically take recognizable forms: initial enthusiasm followed by attention diversion, delegation to insufficient authority levels, departure of the original sponsor without effective handoff, or competing priorities that erode resource allocation.
Implementation methodology should include explicit sponsorship verification and ongoing reinforcement.
The change management methodology
Change management is the most undermanaged element of most enterprise implementations. The methodology that produces successful change management:
Stakeholder analysis. Systematic identification of affected stakeholder groups, their interests, and their potential responses to the change.
Communication planning. Structured communication appropriate to each stakeholder group, beginning early in implementation rather than at deployment.
Training planning. Comprehensive training for affected users, beginning before deployment and continuing after.
Process redesign. Explicit redesign of operational processes to accommodate the new system, rather than implicit assumption that processes will adapt.
Performance measurement adjustment. Review and adjustment of performance measures that may conflict with desired post-implementation behaviors.
Resistance management. Active engagement with resistance rather than ignoring or overriding it.
Change management investment should typically be 15-25% of total implementation budget. Most implementations invest substantially less, producing predictable adoption problems post-deployment.
The scope discipline methodology
Scope discipline distinguishes implementations that complete on time and budget from those that overrun substantially. The methodology requires both pre-implementation rigor and ongoing discipline during execution.
Pre-implementation scope rigor:
- Detailed scope definition with explicit out-of-scope statements
- Stakeholder agreement on scope before implementation start
- Documented assumptions underlying scope decisions
- Estimation methodology with explicit accuracy expectations
During-implementation scope discipline:
- Formal change request process for any scope expansion
- Cost and schedule impact analysis for each request
- Explicit approval authority for scope changes
- Documented decisions for scope changes accepted and rejected
- Regular scope status communication to stakeholders
The challenge in scope discipline is operational rather than methodological. Most implementations have scope change processes but fail to enforce them consistently. The implementations that maintain scope discipline are those where the implementation leader has the authority and willingness to decline scope expansion that would compromise overall implementation success.
The implementation team methodology
Implementation team capability substantially affects outcomes. The methodology for ensuring adequate capability:
Team composition. Specific roles defined with required capabilities, staffed with people who meet the requirements rather than people who happen to be available.
Internal versus external balance. Implementation teams typically benefit from balance between internal staff (who know the organization) and external specialists (who know the technology and implementation methodology).
Authority and accountability. Clear authority for implementation decisions, with corresponding accountability for outcomes.
Sustained team continuity. Implementation teams that maintain continuity throughout the implementation produce better outcomes than teams with significant turnover.
Capability development. Investment in team capability development for ongoing capability after implementation completion.
Common team failures: under-resourced teams that cannot accomplish stated work, teams without authority to make required decisions, teams with inappropriate skill mix, and teams that experience substantial turnover during implementation.
The vendor and partner methodology
External vendors and implementation partners substantially affect implementation outcomes. The methodology for managing external partners:
- Clear partner role definition with corresponding accountability
- Performance metrics with regular review
- Defined escalation paths for partner performance issues
- Knowledge transfer requirements built into partner engagements
- Internal capability development to reduce ongoing partner dependency
Partner selection should evaluate partners as carefully as the underlying technology. Partner capability gaps amplify other implementation challenges.
The user adoption methodology
Technical deployment without user adoption produces failed implementations regardless of technical quality. The methodology for ensuring user adoption:
User involvement throughout implementation. User input on requirements, design, and deployment planning rather than user introduction at deployment.
Comprehensive training. Training matched to actual use cases, with adequate practice opportunity before production deployment.
Performance support resources. Documentation, job aids, and support resources available to users post-deployment.
Adoption measurement. Specific metrics for actual system use, not just deployment completion.
Ongoing support. Continued support for users encountering challenges, with feedback loops to improve the system and processes.
User adoption is often the determining factor between implementation success and failure. The implementations that achieve high user adoption typically invested heavily in adoption methodology; those with low adoption typically did not.
The systematic implementation process
For systematic implementation:
- Verify executive sponsorship and commitment. Before implementation start, ensure adequate sponsorship.
- Conduct comprehensive planning. Including scope, change management, team, vendor, and adoption planning.
- Establish governance and decision authority. Clear roles and decision rights for implementation governance.
- Execute with disciplined methodology. Including scope management, change management, and progress measurement.
- Manage risks proactively. Regular risk identification and mitigation rather than reactive response to problems.
- Plan deployment carefully. Including user readiness, support readiness, and rollback contingency.
- Measure adoption and outcomes post-deployment. Adoption measurement, outcome assessment, and lessons-learned capture.
The takeaway
Enterprise implementation methodology has substantial research behind it that systematic application can apply. The framework above identifies the factors that determine implementation outcomes and the methodology for each.
For organizations experiencing chronic implementation failure, the diagnosis is usually inadequate methodology rather than inadequate technology or talent. Systematic implementation methodology typically produces substantial improvement in both implementation success rates and value realization from completed implementations.
