TinyCTO.tv Tech Document Template Notice: This template is a general educational and operational starting point. It is not legal, tax, accounting, investment, procurement, regulatory, security or certification advice. Requirements vary by jurisdiction, organization, contract and risk. Review and adapt it with qualified professionals before relying on it.
Problem Solved
Commercial teams quote fixed-price contracts based on optimistic gut estimates, leaving delivery teams understaffed and underwater when unforeseen technical complexities consume 150% of the budget.
When to Use
- •Costing complex client technology transformation projects, cloud migrations, or bespoke software builds
- •Establishing blended daily rates, onshore/offshore staffing mixes, and non-labor direct expenses
- •Calculating minimum commercial fee floors to achieve organizational gross margin targets (e.g. >= 45%)
When NOT to Use
- •For high-level corporate annual strategic budgeting (use TPL-FIN-001)
- •For rapid agile sprint velocity tracking in an ongoing sprint (use TPL-DEL-002)

Delivery Estimate and Costing Workbook - Worked Case Study
Fictional Entity: Global Core Banking Cloud Migration Delivery Cost Model
Real-world production case study demonstrating complete operational adoption for Global Core Banking Cloud Migration Delivery Cost Model.
- •Modelled 1,840 person-days of delivery effort across 14 specialist engineering, architecture, and QA roles
- •Applied 15% PERT risk contingency reserving $280K against legacy mainframe COBOL interface ambiguity
- •Locked 47.4% gross margin hurdle price protecting profitability against inflationary wage pressures
Frequently Asked Questions
Why is PERT three-point estimation superior to single-point estimation in delivery costing?
Single-point estimates are notoriously susceptible to optimistic cognitive bias and sales pressure. Three-point PERT estimation forces delivery architects to explicitly consider best-case, most likely, and worst-case scenarios, mathematically weighting the most likely outcome while accounting for the long-tail risk of catastrophic delays.
What is the difference between direct cost and fully burdened cost in rate calculations?
Direct cost is the raw compensation paid to an engineer (base salary or vendor daily fee). Fully burdened cost factors in mandatory statutory taxes, employee benefits, healthcare, IT equipment, software seat licenses, recruitment amortizations, and corporate facility overheads. Costing based on direct costs results in phantom profitability that turns into real corporate losses.
How should contingency reserves be managed during fixed-price delivery execution?
Contingency reserves are not discretionary profit or scope-expansion slush funds; they are ring-fenced financial buffers designed to absorb the cost of known risks if they materialize. As project milestones are achieved and associated technical risks expire, contingency reserves are either released into realized profit or reallocated to remaining high-risk phases.
