Sometimes the hardest part of improving quality is not the technical work – it is getting management and procurement to say “yes” to training, vendor inspection hours or better QA tools.
This NTIA guide gives you:
- A clear framework for writing strong justification letters and emails, and
- A pack of ready-to-use templates you can adapt for your own company.
All templates are written from the perspective of QA/QC, inspection, reliability and procurement teams working on industrial projects.
1. What Is a Justification Letter in Engineering Projects?
In our context, a justification letter (or email) is a short, structured document that:
- Explain what you are asking for (training, vendor inspection, software, templates, tools).
- Shows why it matters for the project or asset (risk, quality, reliability, HSE, schedule).
- Clarifies cost vs impact (what it costs now, what it can save later).
- Makes it easy for a manager or buyer to approve in one go.
Typical examples for NTIA’s audience:
- Approving budget for a technical training such as Industrial Valve Inspection & Testing Training.
- Adding vendor/third-party inspection to a purchase order for critical equipment.
- Buying Master Inspection Templates Pack (ZIP): ITP, Checklists, Forms to standardise QA documentation.
- Adding stronger inspection & testing requirements into a PO or framework agreement.
2. 5 Elements Every Strong Justification Letter Should Include
Before you use the templates, keep this structure in mind. You can reuse it in almost any letter:
- Problem or risk
- Describe a real issue: recurring NCRs, delayed deliveries, weak inspection coverage, repeat failures, unclear documentation.
- Proposed solution
- Training, vendor inspection, tools or resources you want to invest in.
- Business impact
- How it will reduce risk, rework, downtime, claims, schedule pressure, or improve compliance and client satisfaction.
- Cost picture
- Direct cost (course fee, man-days, licence).
- Contrast this with the potential cost of doing nothing.
- Commitment & follow-up
- What you will deliver in return: improved procedures, shared lessons, updated templates, better reports.
Every template below follows this logic, but in a concise, manager-friendly tone.
3. Template A – Training Justification Letter
(e.g. Industrial Valve Inspection & Testing Training)
Use this when:
You are a QA/QC engineer, inspector or reliability engineer and you want approval to attend a technical training course – for example Industrial Valve Inspection & Testing Training.
You can send this as an email or a formal memo. Replace text in [BRACKETS] with your own details.
Template A.1 – Email version
Subject: Request for Approval – [Course Name]
Dear [Manager Name],
I would like to request approval to attend [Course Name] on [Dates], delivered by NTIA. The course focuses on [short summary, e.g. industrial valve inspection, testing and reporting] and is directly relevant to my work on [Project/Asset].
Over the past [X months/years], we have seen recurring issues related to:
- [e.g. incomplete valve inspection reports and NCRs],
- [e.g. inconsistent interpretation of EN 10204 certificates and MTRs],
- [e.g. late detection of vendor nonconformities].
This course specifically addresses:
- how to plan and execute vendor inspections using ITPs and checklists,
- how to apply standards such as API 598 / ISO 5208 during valve testing,
- how to write clear inspection reports, IRs and NCRs.
The expected benefits for our team are:
The total cost of the course is [€X] (excluding/including travel). This is significantly lower than the cost of:
- one day of unplanned downtime or re-work on a critical line, or
- a single rejected batch of valves requiring return to vendor.
After the course, I will:
- share the key lessons with the team in a short internal session,
- review our current inspection templates and reports against the course guidance,
- propose updates to our procedures in line with NTIA best practice.
Please let me know if you need any additional information.

You can adapt the bullets to reflect your own pain points: NCRs, client comments, delays, warranty issues or audit findings.
4. Template B – Vendor / Third-Party Inspection Budget Justification
(Per PO or Project)
Use this when:
You need to justify adding vendor inspection / third-party inspection to a purchase order or project budget for critical equipment (valves, pressure vessels, rotating equipment, etc.).
Template B.1 – Memo or email to Project Manager / Procurement
Subject: Justification for Vendor/Third-Party Inspection – [PO / Package ID]
Dear [Manager Name],
I recommend that we include a dedicated vendor/third-party inspection budget for [PO / Package ID, e.g. valves for Unit X].
This package is critical because:
- [e.g. it contains safety-critical shutdown valves for high-pressure hydrocarbon service],
- [e.g. late delivery or quality issues would directly impact the mechanical completion date],
- [e.g. past projects with similar vendors/equipment have generated significant NCRs and rework].
Without structured vendor inspection, we accept higher risks of:
- nonconforming materials (wrong grade, missing EN 10204 3.1/3.2 certificates),
- valves failing hydrostatic or seat leak tests at site instead of at vendor works,
- incomplete IR/NCR documentation, making warranty and claims harder to enforce.
By including vendor/third-party inspection based on Vendor Inspection ITP Template (Excel) + How to Use and Build an ITP & QCP for Vendor Surveillance, we can:
- detect quality issues earlier and require corrective actions before shipment,
- verify nameplates, MTRs and test results in line with Valve Inspection Checklist (PDF): Visual, Dimensional, Testing,
- reduce the likelihood of repeated nonconformities described in Common Vendor Nonconformities & Fixes.
The estimated cost is [€X] for [Y] inspection man-days (shop visits and document review). This is typically much lower than:
- the cost of one reshipment or urgent site rework,
- liquidated damages for schedule delay, or
- lost production if a critical valve fails after commissioning.
I propose that we:
- include vendor inspection scope and hold/witness points in the PO using Master Inspection Templates Pack (ZIP): ITP, Checklists, Forms,
- appoint an independent inspector through NTIA or our existing inspection framework,
- require a complete dossier (IR, NCRs, test records) as described in Vendor Inspection Reporting: IR/NCR/Final Dossier.
I am available to discuss the details and to align the inspection scope with project cost and schedule constraints.
Kind regards,

You can add a short annex showing examples of past NCRs or delays to make the argument even stronger.
5. Template C – Justification for Master Inspection Templates & QA Tools
Use this when:
You want management to invest in better QA tools, such as Master Inspection Templates Pack (ZIP): ITP, Checklists, Forms, instead of continuing with ad-hoc spreadsheets and one-off documents.
Template C.1 – Email to QA/Engineering Manager
Subject: Justification – Master Inspection Templates Pack (ITP, Checklists, Forms)
Dear [Manager Name],
Our current inspection documentation for vendor packages is based on locally developed spreadsheets and Word documents, which differ from project to project. As a result, we face recurring issues such as:
- inconsistent inspection scopes and hold points between packages,
- missing checks (for example, PMI or documentation review) in some ITPs,
- extra time spent rebuilding forms for each new project,
- limited standardisation in IR/NCR formats.
To address this, I recommend that we adopt Master Inspection Templates Pack (ZIP): ITP, Checklists, Forms from NTIA. This pack provides:
- standard ITP templates aligned with Build an ITP & QCP for Vendor Surveillance,
- checklists that link directly to technical guides such as Valve Inspection Checklist (PDF): Visual, Dimensional, Testing and API 598 vs ISO 5208: Valve Testing Acceptance,
- reporting forms consistent with Vendor Inspection Reporting: IR/NCR/Final Dossier and Write a Valve Inspection Report (With Sample).
Expected benefits are:
- reduced engineering time to prepare ITPs and inspection forms for each project,
- fewer missed checks and clearer expectations for vendors,
- easier training and onboarding of new inspectors and QA/QC staff,
- better traceability and alignment with ISO 9001 requirements for planning and control of externally provided processes.
The one-time cost of the templates pack is [€X], while we currently spend:
- [Y] hours per project creating and revising custom forms, and
- additional time dealing with NCRs that result from missing or unclear inspection requirements.
I believe this is a cost-effective way to standardise our vendor inspection documentation and to align our practice with the guidance available from NTIA. I am happy to perform a pilot on [Project/Package] and report back on time savings and quality improvements.
Kind regards,

You can add a short table with “Current state vs With templates” if your manager prefers numbers.
6. Template D – Justification for Reliability / Inspection-Related CapEx or Opex
Use this when:
You need a budget for inspection-related improvements – for example, more thorough inspection scope on critical valves, additional PMI/NDT, or investment in test equipment.
Template D.1 – Business-case style memo
Subject: Business Case – [Inspection / Reliability Initiative Name]
Dear [Manager Name],
This note outlines the business case for [initiative, e.g. enhanced valve inspection and PMI program for Unit X].
- Current situation
- Over the last [X years], we have had [N] valve-related failures / leaks / unplanned repairs on [Unit/Asset].
- These events caused an estimated [Y hours] of downtime and [€Z] in direct and indirect costs (labour, lost production, rework).
- Root cause analyses and reviews, such as those summarised in Top 20 Valve Failure Modes & Root Causes, show that material and inspection issues (wrong grade, inadequate testing, poor documentation) are recurring factors.
- Proposed improvement
I propose that we:
- increase inspection coverage for critical valves using guidance from Valve Inspection Checklist (PDF): Visual, Dimensional, Testing,
- include PMI in line with PMI Testing: What, When & How to Document for selected alloy and stainless valves,
- standardise reporting using Vendor Inspection Reporting: IR/NCR/Final Dossier.
- Cost estimate
- Additional inspection hours per year: [X]
- Incremental PMI / testing cost per year: [Y]
- Total annual cost: approximately [€A].
- Expected benefit
Conservative estimates suggest that preventing even one major valve failure or unplanned outage per year would:
- avoid [B hours] of downtime, worth approximately [€B] in lost production alone,
- reduce emergency maintenance and rework costs,
- improve audit findings and compliance with client expectations.
On this basis, the payback period for the initiative is expected to be [< 1 year / X months], with additional non-financial benefits such as improved safety and reputation.
I would welcome the opportunity to present this proposal in more detail and to refine the numbers with input from Finance and Operations.
Kind regards,
[Your Name]
[Your Role]
Adjust the numbers and references to match your asset and history – even approximate figures can make your case stronger.
7. Template E – Justification to Procurement for Stronger QA/Inspection Requirements in POs
Use this when:
You want procurement to accept stronger QA and inspection clauses in a PO or framework agreement, not just “standard” documentation.
Template E.1 – Email to Buyer / Category Manager
Subject: QA/Inspection Requirements for [Equipment Category] Purchase Orders
Dear [Buyer Name],
To reduce quality risk and avoid disputes with vendors, I recommend that we update our standard purchase order conditions for [equipment category, e.g. industrial valves] to include more explicit QA/inspection requirements.
Based on experience and lessons captured in Common Vendor Nonconformities & Fixes and Vendor Inspection Reporting: IR/NCR/Final Dossier, the key issues we see today are:
- incomplete or missing EN 10204 3.1/3.2 MTRs,
- valves supplied with incorrect or unclear test documentation (API 598 vs ISO 5208),
- limited visibility of vendor quality plans, ITPs and NCR handling.
To address this, I propose we include in our POs:
- an agreed inspection and test plan, based on Vendor Inspection ITP Template (Excel) + How to Use,
- clear requirements for Valve Inspection Checklist (PDF): Visual, Dimensional, Testing and valve test standards as per API 598 vs ISO 5208: Valve Testing Acceptance,
- documentation deliverables aligned with Vendor Inspection Reporting: IR/NCR/Final Dossier (IRs, NCRs, test records, certificates).
These changes will:
- give vendors clearer expectations from the start,
- reduce the number of late clarifications and commercial disputes,
- support procurement in enforcing quality requirements objectively.
I can provide draft clauses and example annexes using Master Inspection Templates Pack (ZIP): ITP, Checklists, Forms, so that the impact on your workload is minimal.
Please let me know if you would like to review the proposed text together.
Kind regards,
[Your Name]
[Your Role]
This template helps align QA and procurement so POs reflect real inspection needs, not only price and delivery.
8. How to Customise These Templates for Your Company
To make these letters work in your environment:
- Use your own numbers and examples
- Reference real NCRs, delays, audit findings or warranty claims from previous projects.
- Align terminology with your procedures
- If you use different names for IR, NCR, QCP, etc., adjust the text so readers feel it is “their” language.
- Connect to your management’s priorities
- Some managers care most about schedule, some about HSE, some about cash. Emphasise the angle that fits your audience.
- Tie changes back to NTIA resources you actually use
- Keep letters short
- Whenever possible, keep the body of your email to 300–400 words and move detailed numbers or examples into a short attachment.
9. Build Your Own Justification Library with NTIA
At NTIA, we see the same pattern across many clients: technically strong engineers know what needs to be done for quality and reliability, but they struggle to translate that into clear, persuasive requests for management and procurement.
You can use this article to:
- Build your own internal “Justification Library” in your QA or engineering folder.
- Attach the relevant letter templates to your ITPs, QCPs and inspection plans from NTIA.
- Train new inspectors not only in how to inspect, but also in how to secure the resources they need.
Whenever you need deeper technical support – especially around valves – you can combine these letters with:
- Industrial Valve Inspection & Testing Training – for hands-on competence building.
- Master Inspection Templates Pack (ZIP): ITP, Checklists, Forms – for ready-made documentation.
- The wider NTIA content library on vendor inspection, materials, PMI and receiving inspection.
That way, each new project has not only the technical tools, but also the management buy-in to use them properly.
