The challenge
A pharmaceutical manufacturer required a structured way to examine the activities and resources associated with GMP compliance.
The task involved several related questions: which activities were relevant, how their resource requirements could be estimated, what assumptions were necessary and what further evidence would improve the assessment.
A single headline estimate would not adequately communicate those distinctions. The analysis needed to be transparent, editable and traceable to the questions it was intended to address.
It also needed to distinguish the technical requirement for an activity from the separate rules governing whether its expenditure belonged within the particular assessment.
The contribution
Jon developed a spreadsheet model supported by an activity ledger, an assumptions register, supplementary questions and commentary on gaps and overlaps.
Further work included a cost-classification model, a draft supporting procedure and an evidence matrix linking technical propositions with records and attributable resources.
The approach
Structuring the model around identifiable activities
The model connected activities with the questions under consideration rather than relying solely on broad departmental totals.
This provided a basis for examining the relationship between operational work and the scope of the assessment.
Making assumptions visible and editable
Assumptions were recorded explicitly, with editable inputs linked to the calculations.
This allowed the effects of revised information to flow through the model and made it easier to identify which estimates depended on uncertain inputs.
Providing control over inclusion
The activity ledger included a mechanism for including or excluding activities from the relevant analysis.
This supported transparent treatment of scope and helped distinguish an activity’s existence from its eligibility within the particular model.
Identifying evidence gaps
Supplementary questions recorded the information needed to improve accuracy. Commentary highlighted gaps and overlaps, while the evidence matrix connected technical explanations with supporting records and associated resources.
The outcome
A structured model and supporting documents were supplied for review and further refinement.
The deliverables provided a transparent basis for discussing assumptions, testing scope and identifying further evidence requirements.
They were not presented as audited accounts or a universal standard for calculating GMP costs. Their value lay in making the particular assessment explicit and reviewable.
What this assignment demonstrates
The assignment demonstrates Jon’s ability to translate complex operational obligations into a structured analytical framework.
It illustrates an approach that combines technical understanding with traceability, clear assumptions and practical tools for updating the analysis as better information becomes available.
