The T-15 Readiness Process

Where Confidence Stops Being a Feeling and Becomes a System

Every shutdown team wants confidence.
Very few can explain where it actually comes from.

In high-performance turnarounds, confidence is not optimism.
It is the measurable output of structured readiness.

And the most effective readiness system we've built is the T-15 Process — a gate-based model that eliminates uncertainty long before Day 1.

T-15 establishes five major readiness checkpoints:

T-15 → T-12 → T-9 → T-6 → T-3

At every gate, the team is evaluated against roughly 100 readiness criteria across the 10 domains that determine whether the shutdown will run safely, predictably, and on schedule.

Between gates, the cross-functional team works deliberately to close gaps, upgrade the plan, and raise the maturity of the entire turnaround.

This is the system that restores confidence — not as a feeling, but as a verifiable condition.

Why T-15 Matters: The Data Behind Predictability

Global statistics paint a brutal picture of capital project execution:

PwC research shows:

• 94% of capital projects exceed their planned budgets, and
• nearly 80% run late.

This pattern holds even in world-class organizations.

The root cause is almost always the same: insufficient readiness in the earliest phases.

AP-Network's benchmarking confirms the same readiness–performance correlation:

At 50% readiness, the most likely schedule overrun is 30% ± 15%,

meaning 15% to 45% delay,
with cost growth ranging from 0% to 30%.

At 90% readiness,

• budget overruns become nearly nonexistent, and
• schedule deviation stays within ±5%, with a measurable opportunity for early completion.

This is exactly the performance curve the T-15 Process is designed to control.

T-15 raises readiness deliberately, gate by gate — moving the project from the risk profile of an average shutdown to the performance profile of a top-quartile one.

The 10 Readiness Domains Assessed at Every Gate

T-gates measure progress across the 10 dimensions that directly predict turnaround outcomes:

1. Risk & Process Safety Control
2. Material Readiness
3. Scoping Efforts
4. Major Contracts & Subcontracts
5. Engineering & Work Scope Development
6. Level of Project Schedule
7. Project Management Team Readiness
8. Operations Support Team
9. Work Packs
10. Project Controls Metrics

These ten dimensions give a complete, 360° picture of where the shutdown stands — and what must improve before the next gate.

How the T-15 Gate System Works

T-15 Months — Direction Set

• Strategy defined.
• Scope roughly shaped.
• Long-lead procurement initiated.
• Preliminary schedule architecture built.
• Major risks mapped.

T-12 Months — Structure Formed

• Scope stabilizes.
• Engineering requirements clarified.
• Contracting strategy locked.
• Long-lead commitments secured.
• Schedule logic advances.

T-9 Months — Plan Assembled

• Detailed planning accelerates.
• Most engineering deliverables completed.
• Contractors aligned with execution approach.
• Work packs enter structured development.

T-6 Months — Execution Model Ready

• Integrated schedule nearly complete.
• Work packs drafted and consistent.
• Material readiness visible.
• Operations aligned.
• Risks assigned with mitigation plans.

T-3 Months — Full Readiness Confirmed

• Refined schedule with T-session outputs.
• Work packs complete.
• Materials staged.
• Contracts mobilization-ready.
• Operations handover strategy locked.

At this point, readiness is no longer subjective — it is measurable.

Why T-15 Works

1. Early identification of failure modes

Issues found at T-15 cost hours to fix.
Issues found at T-3 cost weeks — or shut down the TAR.

2. Cross-functional synchronization

Maintenance, Operations, Projects, Engineering, Supply, HSE —
all operating with a single cadence and a shared view of priorities.

3. Predictable maturity growth

Each gate raises the standard.
No surprises later.

4. Higher schedule and cost certainty

Because readiness directly determines predictability —
as confirmed by AP-Network benchmarks.

5. A team walking into the shutdown already aligned

• Roles clear.
• Tools ready.
• Execution model understood.
• Confidence justified.

This Is What On-Site Support Looks Like

Our on-site model is built around T-gates.

We guide your teams through every domain, at every stage, ensuring readiness grows in a controlled, structured, measurable way.

You're not "hoping" the shutdown succeeds, you understand why it will.
