Procurement & Client Engagement
J. B. Fowler does not advertise and does not accept unsolicited commercial approaches. New client relationships are established exclusively through professional referral or institutional introduction. This is a matter of due diligence: the confidentiality requirements of the work mean the firm must know, with confidence, the identity of the commissioning organisation and the purpose for which the materials will be used.
Prospective clients are typically introduced by an existing client, a partner organisation, or a professional contact within the assessment community. Introductions through standards bodies and professional associations in the psychological assessment sector are also accepted.
Engagement Process
I. Introduction. A prospective client is introduced through one of the channels described above.
II. Specification Development. The firm works with the client to define material requirements, production standards, quality thresholds, and documentation needs. This specification becomes the governing document for the entire engagement.
III. Due Diligence. Verification of institutional status, intended use of materials, and any regulatory or ethical considerations relevant to the engagement. Enhanced in 2024 following the sector-wide governance review.
IV. Agreement. Formalisation through a written agreement covering specification, production timeline, quality standards, confidentiality obligations, chain of custody, delivery, and payment terms.
V. Production. Execution under the three-stage quality assurance framework with progress updates at defined milestones.
VI. Delivery & Documentation. Materials delivered with full production documentation, chain of custody records, and quality assurance data.
Engagement Parameters
| Minimum Run | Determined by specification, not by a fixed rule. The smallest run in company history was 47 copies; the largest exceeded 50,000 units. |
|---|---|
| Timeline | Specification-dependent. Small standard runs: weeks. Large institutional runs or non-standard specifications: months. Large-scale digitisation projects: scoped in phases, may extend across years. |
| Expedited Production | Not offered. The quality assurance framework requires defined stages with verification at each stage; these cannot be compressed. |
| Confidentiality | Non-disclosure agreement as standard for all engagements. Binding on all personnel beyond employment term. |
| International Shipping | Managed through specialist logistics partners. Chain of custody documentation extends to international transit. |
The firm does not publish client names, case studies, or material specifications without explicit written authorisation. Current and past engagements are not discussed with prospective clients. References are available on request through professional introduction.
