Three Engagements, Three Distinct Outcomes
Each service is scoped around a specific business challenge โ with a defined timeline, a named deliverable, and a clear measure of completion. Choose the engagement that matches your current situation.
Back to HomeHow We Approach Each Engagement
All Chang Arch engagements follow the same underlying approach: begin with structured observation and dialogue, convert what we find into documented form, and close with written outputs that the client can act on independently.
We do not begin analysis until we have a clear picture of the current state. Premature recommendations are one of the most common failure modes in consulting โ and one we specifically work to avoid by investing time at the front of every engagement in understanding before advising.
Scope & Align
Define the specific challenge, agree on the engagement structure, and establish what a successful output looks like.
Observe & Analyse
Conduct structured sessions, review existing documentation, and map the current state before drawing any conclusions.
Draft & Refine
Produce initial written outputs, share with the client for review, and refine based on feedback before finalising.
Deliver & Debrief
Present final deliverables, walk through key findings or content, and confirm next steps for implementation.
Business Model Clarity Session
A condensed yet substantive advisory engagement for founders and executives who want to pressure-test their business model assumptions. Through structured dialogue and lightweight modelling, a senior consultant reviews your revenue logic, cost architecture, and value delivery mechanism. The outcome is a business model clarity memo that distils key assumptions, highlights areas of structural tension, and offers perspectives on where adjustments might strengthen the overall design.
Most suited to: startups and SMEs at an inflection point โ those considering a pivot, entering a new market, or seeking external validation of their current model before making significant investments.
What the Engagement Covers
- Revenue logic review: how the business generates income relative to the value it creates
- Cost architecture analysis: fixed vs variable cost structure and its implications for scaling
- Value delivery mechanism: how the product or service actually reaches and benefits customers
- Assumption mapping: identifying which assumptions underpin the model and their relative fragility
- Written clarity memo: structured document summarising findings and perspectives
Process Documentation & Standardisation
A methodical engagement that captures how work is currently performed across your organisation and translates tribal knowledge into structured, shareable documentation. Over 5 weeks, the consulting team conducts observation sessions, staff interviews, and workflow tracing to produce a process library covering key operational areas. Each documented process includes purpose statements, step sequences, role assignments, and quality checkpoints.
The library is delivered in an editable format suitable for your internal knowledge management system. Most suited to: businesses preparing to scale their team, manage a leadership transition, pursue a certification, or bring operational consistency to a growing organisation.
Engagement Process
Investor Readiness Preparation
A structured program for companies preparing to engage with potential investors, covering narrative development, financial presentation refinement, due diligence preparation, and pitch rehearsal. The engagement moves through four phases โ story architecture, numbers clarity, documentation assembly, and presentation practice โ with deliverables at each stage.
Designed for growth-stage companies seeking Series A or B funding. Most suited to: businesses with proven revenue traction that are preparing for their first or second institutional fundraising round.
Program Deliverables
- Refined investor narrative โ a clear, honest story about the business and its trajectory
- Financial model review memo โ observations on presentation clarity and assumption robustness
- Virtual data room structure โ organised documentation framework ready for investor due diligence
- Two facilitated mock pitch sessions โ with detailed written feedback after each session
