Why Do I.T. Projects Fail?

25% of technology projects fail outright, and 54% of IT project failures can be attributed to project management. Understanding the triple constraint — and the often-overlooked People constraint — is key to delivering successful implementations.

The Hard Truth About I.T. Projects

"25 percent of technology projects fail outright; 20 to 25 percent don't show any return on investment; and as much as 50 percent need massive reworking by the time they're finished."

"54 percent of IT project failures can be attributed to project management, whereas only 3 percent are attributed to technical challenges." — Forbes Magazine


The Project Management Triple Constraint

All projects are carried out under certain constraints — traditionally, they are Cost, Time, and Scope. These three factors are commonly called "the triple constraint."

However, a major constraint seldom given enough attention is PEOPLE as a resource — and that constraint carries the highest importance of any project. PROCESS and UNDERSTANDING are the last constraints that most often lead to failure.


Top 10 Reasons I.T. Projects Fail

  1. Lack of System Ownership by company resources (Quality Assurance)
  2. Minimal System/Business Process Documentation — Are documents current?
  3. Failure to Align Subject Matter Experts and Implementation Team — not on the same page
  4. Scope Creep on requirements (Boiling the Ocean)
  5. Resource Allocation Issues — over or under allocated
  6. Unclear Project Initiatives — What are we rolling out?
  7. Poor Communication — Knowledge transfer to support changes
  8. Ineffective Management — Leadership over their head
  9. Unrealistic Deliverable Dates — Bad assessment
  10. Inability to Adapt to Change — Alter Time, Cost, or Scope

Best Practices by Constraint

Cost Best Practices

  • Use a project management tool to track resource hours, tasks, and hourly rates on a weekly basis.
  • Provide detailed forecasting for each phase of the project.
  • Have resources provide realistic projections and updates on tasks.
  • Do not over-allocate resources assigned more than 15% of critical path tasks.

Scope Best Practices

  • Track Statement of Work (SOW) deliverables to every project task and align with all resources and timelines.
  • Do not allow customers to fall into scope creep.
  • Do not allow sales teams to under-scope projects; allow 20-25% slack time in deliverable dates.
  • Ensure Risk Analysis is well documented if the project is NOT following best practices.

Time Best Practices

  • Ensure the project is scoped correctly by experts — sales teams cannot adequately scope projects without input from technical and functional experts.
  • Always provide a detailed and summarized project plan outlining milestones and critical paths.
  • Follow triple constraint logic to ensure delivery dates do not jeopardize project costs and/or quality.
  • Remember: adding more resources to a task does not mean it will be completed faster. Having the right expertise matters more.

People Best Practices

  • Select resources that are Subject Matter Experts (SMEs) for their assigned tasks. If they are not, allow time for training and onboarding.
  • Do not expect resources with full-time production responsibilities to fulfill project tasks on time without reducing their day-job workload.
  • If a resource cannot estimate how long a task will take, choose another resource.

Process Best Practices

  • Customers should know their business processes and provide details in writing.
  • Ensure the correct SMEs are involved in all process conversations.
  • During design sessions, highlight inefficient processes that can be automated or streamlined.
  • Document risky processes and their associated workarounds.

Understanding Best Practices

  • Apply quality management: ensure all project activities are effective and efficient with respect to the objective.
  • Client teams should be trained and onboarded on new software/hardware.
  • Client support teams should receive knowledge transfer from both functional and technical perspectives.
  • Client teams should have Break/Fix and FAQ documentation to resolve issues faster.

Quality Best Practices

  • Define User Acceptance Testing (UAT) with clear quality metrics.
  • Aim for an 80-98% success rate — 100% is not realistic.
  • Ensure Change Management and Vendor Management processes are aligned to quality metrics.
  • Align end-user expectations with final deliverables.
  • Better to under-promise and over-perform.
  • Better to deliver a good product late and working than on-time and lacking functionality.
  • Do not chase delivery dates — dates should be based on quality metrics, not just cost.

The ROI Reality

No organization buys enterprise software for the sake of owning it — it's all about Return on Investment (ROI). The best-fit software maximizes benefits and delivers the highest possible return. I.T. implementations require experienced resources and strong PMO methodologies.

Consider this analogy:

  1. Consumers pay $70-$180/hour for automobile repairs. The more expensive the vehicle, the higher the cost to repair.
  2. Corporations pay millions of dollars to implement software/hardware packages. The more expensive the system, the higher the cost to fix it.
  3. Yet corporations often look to pay bottom dollar for system maintenance and training — and that is a costly mistake.

Hiring staff with junior-level expertise can cost your project in 5 critical ways:

  • Lost hours of productivity
  • Increased hours to complete the project
  • Increased rework hours
  • Decreased quality of project deliverables
  • An inefficient delivered solution

3 Questions Before Your Next I.T. Project

  1. How well has your organization performed in the last 10 years of I.T. implementations? Are you getting better or worse?
  2. Why are you missing the mark? How will you ensure better success going forward?
  3. Who can you reach out to for assistance?
