The plan must be tied to a real named organisation and a specific strategic context, not a generic template. Proof requires review by a practitioner who can confirm the roadmap is grounded in the organisation's real constraints and that the budget and resource assumptions are defensible.

Milestone map

0 milestones · 6 weeks

Proof requires review by someone who works within or oversees the mapped process and can confirm the map is accurate.

Milestone map

The deliverable is a bottleneck analysis document with the supporting data and an improvement proposal with measurable targets. Proof requires review by an operations professional who can confirm that the identified bottleneck is real and the improvement proposal is technically sound.

Milestone map

The audit must be grounded in real data from real suppliers or operators, and at least one supply-chain participant must be interviewed. Proof is the audit document plus documentation of the interview(s), confirming the supply chain characterisation is accurate rather than desk research alone.

Milestone map

Build an Operations Metrics Dashboard

0 milestones · 6 weeks

Design and build a dashboard tracking the key performance indicators of a specific real operational function — production, logistics, customer service, or similar — using real data from that function. The dashboard must make at least one non-obvious operational insight visible that was previously hidden in raw data. Proof requires validation by someone who works in the operation, confirming that the metrics captured are the ones that actually matter for managing that function and that the data is real.

Milestone map

Conduct Primary Market Research

0 milestones · 8 weeks

Design and execute original market research using real participants — a minimum of 15 structured consumer interviews plus a survey with at least 50 respondents — and synthesise the findings into a research report that identifies distinct market segments, key purchase drivers, and unmet needs. Proof is the research report plus the interview guides, showing real participant responses rather than fabricated data. A practitioner with marketing or consumer research experience must review the report and confirm the methodology is sound and the insights non-trivial.

Milestone map

Audit a Real Brand's Market Position

0 milestones · 6 weeks

Conduct a rigorous audit of a real brand's market position — covering brand positioning, visual identity, messaging consistency, customer perception, and competitive differentiation — and produce a written audit document identifying specific gaps between the intended and actual brand experience. The audit must address a real named brand using real evidence (public materials, customer reviews, competitor positioning). Proof requires submission to and review by a marketing professional who can confirm the assessment is analytically grounded rather than opinion-based.

Milestone map

Design a Marketing Campaign for a Real Organisation

0 milestones · 8 weeks

Design a complete marketing campaign brief for a real organisation — specifying the campaign objective, target audience, channel strategy, budget allocation, key creative direction, KPIs, and measurement plan. The brief must be for a real organisation with a real marketing challenge, not a simulation. Proof requires that the campaign brief be reviewed by a marketing practitioner before execution begins, or formally presented to the organisation's marketing leadership, with documented feedback on whether the strategy is viable.

Milestone map

Analyse a Real Marketing Campaign's Performance

0 milestones · 6 weeks

Conduct a rigorous retrospective analysis of a real marketing campaign using real performance data — either a campaign you ran, or a real documented campaign with published performance metrics. The analysis must identify what drove results, what failed, and what a future campaign would do differently, grounded in the actual numbers rather than speculation. Proof requires review by someone who has run a real marketing campaign and can confirm the performance attribution is sound and the conclusions non-obvious.

Milestone map

Analyse Consumer Behaviour Using Real Data

0 milestones · 8 weeks

Analyse the purchasing behaviour of a real consumer cohort using real data — transaction records, survey responses, observational data, or published research datasets — and produce a written analysis identifying the key behavioural drivers, segmentation patterns, and business implications. The data source must be cited and verifiable. Proof requires review by a marketing or consumer research practitioner who can confirm that the analysis goes beyond summarising the data to identifying genuinely useful strategic insight.

Milestone map

Build a Three-Statement Financial Model for Industry Analysis

0 milestones · 6 weeks

Build a complete, linked three-statement financial model (income statement, balance sheet, cash flow statement) from publicly available filings for a real company, and use it to identify the key drivers of financial performance — not merely to reconcile the statements. The model must include at least two years of historical data and a one-year projection with documented assumptions. Proof requires review by a finance professional who can confirm that the model links correctly, the projection assumptions are explicit and defensible, and the performance driver analysis is analytically sound.

Milestone map

Value a Real Company Using DCF or Comparable Analysis

0 milestones · 10 weeks

Perform a full valuation of a real publicly traded or recently acquired company using either a discounted cash flow model or comparable company analysis — with fully documented assumptions, sensitivity analysis showing how the valuation changes under different scenarios, and an explicit investment thesis or price target conclusion. The valuation must be for a real company using real financial data. Proof requires review by a finance professional or university finance faculty member who can confirm the methodology is technically correct and the assumptions are documented.
