A document-based written audit of your anodizing, hard anodizing, or powder coating process — by Balasubramanian Iyer, directly. No live call required. The deliverable is a structured report you can share with your team, vendors, or board.
Not a generic "process overview." Not a sales pitch dressed up as a deliverable. Four pages of focused analysis on your specific situation, written so a plant manager and a founder can both read it.
Delivered as a PDF within seven working days of payment + document receipt. The format is repeatable — many buyers commission a second audit 90 days later to see what moved.
Both are paid, both go directly to Iyer, both come with structured deliverables. They solve different problems.
| Async written audit · ₹15,000 | Paid scoping call · ₹5,000 | |
|---|---|---|
| Format | Send documents, receive report | 45-minute live video call |
| Best when | The question requires reviewing documents in detail; you want a written record more than a conversation; your team and our calendars don't overlap | You have a focused question to discuss in real time; you'd rather hear the reasoning live than read it |
| Deliverable | Four-page PDF report | Recording + one-page written summary |
| Turnaround | 7 working days from payment + documents | 3-5 working days to schedule, 24h post-call for deliverables |
| Credit toward future work | Deductible from a paid engagement signed within 90 days | Deductible from a paid engagement signed within 90 days |
Many buyers do both — audit first, then scoping call to discuss the recommendations.
The written audit is a remote-led engagement structured to give you a complete technical picture of your line without us being on-site. It works when there is enough documented data to analyse and when the issue is amenable to remote diagnosis. The deliverable is structured into the sections below.
Equipment inventory: tanks, rectifiers, chillers, racking systems, effluent treatment, with rated capacities and current condition. Substrate and product mix: alloys processed, part geometries, throughput in m²/month. Documented process parameters: SOPs, parameter sheets, QC protocols.
Sample data from 60–90 days of bath analysis (titration logs you provide; or fresh samples sent to a third-party lab when documented data is thin) is plotted against the documented operating windows. Each bath gets a variance assessment — frequency of out-of-spec days, magnitude of drift, correlation with production defects. Common chemistry-driven issues: anodize bath running hot in summer months, caustic etch over-saturated with dissolved aluminium, sealing tank pH drifting outside the 5.5–6.0 working window, contamination accumulation (chloride, iron, organics).
Production data for 90 days gets analysed against the documented capacity: m²/day actual vs theoretical, shifts running below capacity, batch-to-batch consistency. Rejection records get re-classified by failure mode and Pareto-charted to identify whether your output ceiling is currently chemistry-limited, throughput-limited, or rejection-limited.
Rectifier age, output stability, ripple measurement where available, recent service history. Tank condition: lining integrity, agitation pattern, heat-exchanger performance. Chiller capacity vs current demand. Rectifier kWh per m² of coating produced (typical Type II: 1.8–2.5 kWh/m²; hard anodize: 4–6 kWh/m²) benchmarked against industry standards. Chemical consumption in kg/m²: caustic 0.3–0.5 kg/m²; sulphuric acid 1.8–2.2 kg/m²; nickel acetate 0.05–0.10 kg/m².
Documented SOPs compared against what your QC and production data implies actually happens. Common gaps: titration cadence below SOP requirement, parameter sheet revisions not propagated to floor, QC sampling frequency or location inconsistent with SOP, maintenance intervals stretched beyond specification.
Findings get prioritised by ease-of-implementation vs expected impact. Each corrective action has: the specific change, the expected outcome (with numbers), the implementation effort, and the monitoring KPI. Actions are sequenced into a 30/60/90-day timeline so you can roll them out without overwhelming the plant team.

Examples of situations that fit the format well:
The question genuinely needs plant inspection (visual defect patterns, electrical safety review, equipment commissioning) — book an on-site visit instead. The scope is too broad to anchor on documents ("should we enter the anodizing business?") — start with the plant cost calculator and ROI guide.

A ₹15,000 paid review of your anodizing or hard-anodizing process based on documents you send — SOPs, bath chemistry logs, rejection data, supplier quotes, plant layout, MIL-A-8625 compliance scope, etc. Balasubramanian Iyer reviews the documents and delivers a structured four-page written report within 7 working days. No live call is included; the deliverable is the report.
The scoping call (₹5,000) is a 45-minute live video conversation — useful when you have a focused question you want to discuss in real time. The written audit (₹15,000) is asynchronous — Iyer reviews your documents at his own pace and delivers a written report you can share with your team, vendors, or board. Pick the audit when (a) the question requires reviewing documents in detail, (b) you want a written record more than a conversation, or (c) your team's hours don't overlap with available call slots.
Page 1: situation summary as Iyer understands it from your documents, plus assumptions and gaps. Page 2: diagnosis — what the data most likely indicates, with the reasoning chain. Page 3: recommendations — specific actions ranked by priority and effort. Page 4: a punch list of decisions you'll need to make and questions to bring back if you want follow-up.
Whatever you have. The richer the input, the sharper the audit. Useful: current bath chemistry SOPs and last 30 days of logs; rejection data with photos; rectifier and chiller specs; chemical and equipment supplier quotes; plant layout drawings; current and target capacity; MIL-A-8625 / ISO 7599 / IS 1868 compliance gap notes; effluent treatment plant details; prior audit reports. Send what's relevant — Iyer will flag if more is needed before starting.
Yes — if the audit leads to a paid engagement (on-site visit, plant commissioning, ongoing retainer) signed within 90 days, the ₹15,000 is credited toward the first invoice of that engagement.
Yes — send your NDA along with payment and we'll execute it before any document review begins. A standard NDA is offered if you don't have one of your own.
The first short clarification email (under 200 words) is included — Iyer responds within 3 working days. For deeper discussion, book the paid scoping call (₹5,000, deductible against the audit fee if booked within 14 days of report delivery) or escalate to an on-site engagement.
Yes. Send the supplier quotes (chemicals or equipment) plus your operational context, and the audit will benchmark them on technical specs, expected consumption rates, India-relevant compliance, and total cost — not just sticker price. This is one of the highest-leverage uses of the audit format.
Anything that genuinely requires plant inspection (visual rejection patterns, electrical safety review, equipment commissioning), or a question that's too broad to anchor on documents. For the former, book an on-site visit. For the latter, start with the plant cost calculator and ROI guide on the blog.
If we determine after reviewing your initial documents that the audit format isn't the right fit (requires plant inspection, scope too broad, etc.), we refund in full and recommend the correct service. After the report has been delivered, the fee is non-refundable — but the report is yours regardless.
