MKTG90022 Chap.6 Scale-up and Manufacturing
Scale-up and Manufacturing
Scale-up moves a laboratory or prototype process toward repeatable commercial manufacture while protecting performance, quality, safety and economics. Larger scale can change mixing, heat transfer, yield, contamination risk, process time, cleaning and waste. The purpose of each scale run must be explicit: engineering learning, validation, sample production or supply.
CROs provide contracted research services, CDMOs combine development and manufacturing support, and CMOs focus on commercial manufacture. Provider categories overlap, so selection depends on demonstrated capability, quality systems, capacity, communication, cost and intellectual-property terms.
Scale planning names the critical process parameters and quality attributes, then chooses the smallest step capable of testing the next uncertainty. Economics must include failure, downtime, testing, disposal, utilities, depreciation and transfer work rather than only raw materials and labour.
External-provider diligence should examine relevant equipment, technical record, capacity slots, governance, pricing, background platforms and ownership of improvements. Documentation and training preserve learning and make later transfer possible. A transfer-ready process records specifications, methods, batch history, deviations and reasons for key choices.
The commercial recommendation links the proposed scale activity to a decision threshold, funding need and consequence for customers, rather than treating a larger batch as progress by itself.

Scale-up and Manufacturing FAQ
Why can scale-up fail?
Physical conditions, quality controls, raw materials, cleaning, waste, equipment and operator capability can behave differently from the laboratory process. This evidence guides the next operating milestone.
When should scale-up begin?
Begin when the next scale step answers a defined development or commercial question and the process is sufficiently understood to make the learning useful. This evidence guides the next operating milestone.
How do provider roles differ?
CROs concentrate on research services, CDMOs combine development with manufacturing support, and CMOs concentrate on manufacture, although actual service scopes vary. This evidence guides the next operating milestone.
What should partner diligence cover?
Review relevant equipment, technical record, quality systems, capacity, communication, project governance, pricing, background technology, improvement rights, data access and transferability. This evidence guides the next operating milestone.
Assessment move
Draw the process as an operating sequence from raw-material receipt through preparation, production, separation, cleaning, testing, release, storage and waste. Beside every step, list the critical input, controllable parameter, quality attribute, data record and failure consequence. Circle the relationships most likely to change with scale, such as mixing, heat transfer, oxygen transfer, residence time or cleaning burden.
Before proposing a pilot, write the decision it must inform. A run intended to test yield requires different design and sampling from a run intended to make customer material or support validation. Specify success ranges and stop conditions in advance. Extend the cost map beyond raw materials and labour.
Include failed batches, downtime, utilities, testing, disposal, cleaning, depreciation, technology transfer and internal project management. Change one operating assumption and trace how it affects capacity, unit cost, cash need and launch timing. Compare an internal facility with external support under capability, capital, speed, quality, flexibility and dependency. Do not use CRO, CDMO or CMO as a substitute for diligence.
Create questions about relevant equipment, technical experience, quality history, capacity slots, governance, communication, pricing, background platforms, improvement ownership, data access and transfer assistance. Ask what documents will be delivered: batch records, analytical methods, deviations, reports, specifications and training material. Then run a transfer scenario in which the first provider becomes unavailable.
Identify the rights, data and practical know-how needed for another site to continue. Finish by writing a scale recommendation that names the next uncertainty, the smallest informative step, the partner or internal capability required and the evidence that unlocks the following investment. This approach keeps manufacturing milestones connected to learning rather than equating larger equipment with progress.
