Partner & Confidential Engagements
Sienda Ltd may undertake selected assignments on behalf of, alongside, or through other professional advisers, consultancies, agencies, accountancy practices, certification consultants, commercial organisations or other business partners.
Such arrangements may require Sienda to work discreetly behind the principal adviser or contracting organisation.
The purpose of this policy is to explain the general principles applied to those engagements.
1. Nature of the relationship
A partner may engage Sienda to provide business engineering, analysis, research, advisory support, documentation, specialist input or other agreed professional services in support of work being delivered to the partner’s own client.
The precise relationship, scope, responsibilities and commercial arrangements will be agreed for each assignment.
Sienda does not automatically acquire a direct commercial relationship with the partner’s client.
2. Confidentiality and discretion
Sienda treats the identity of the partner, its clients and the circumstances of an engagement as confidential where the nature of the assignment requires it.
Unless otherwise authorised or required by law, Sienda will not:
- publicly identify the partner’s client;
- disclose confidential details of the engagement;
- use the engagement as a public case study;
- publish confidential client information;
- contact the end client for unrelated commercial purposes.
Additional confidentiality obligations may be agreed in writing where appropriate.
3. Client contact
Where Sienda is engaged through another professional or organisation, communication with the end client will follow the arrangement agreed with the partner.
Sienda will not ordinarily establish a separate commercial relationship with the end client in connection with the same assignment without appropriate discussion with the partner.
Direct contact may nevertheless be appropriate where it is necessary for the work and has been agreed as part of the engagement.
4. Branding and presentation
Where appropriate, reports, analyses, documents or other deliverables may be supplied without Sienda branding or in a format suitable for incorporation into the partner’s wider work.
Any right to rebrand, reproduce, adapt or distribute Sienda deliverables will be agreed for the particular engagement.
Unless otherwise agreed, Sienda retains ownership of its pre-existing methodologies, frameworks, templates, know-how and other background intellectual property.
5. Professional independence
Confidential or partner-led delivery does not alter Sienda’s commitment to independent professional judgement.
Sienda will not knowingly support:
- misleading conclusions;
- inaccurate representations;
- unlawful activity;
- concealment of material professional concerns;
- claims that Sienda believes cannot reasonably be supported.
Where Sienda identifies a material issue affecting its work, it may raise that issue with the contracting partner and, where appropriate, decline or discontinue the relevant assignment.
6. Partner responsibilities
The contracting partner remains responsible for its own relationship with its client, including:
- pricing;
- contractual commitments;
- representations made to the client;
- collection of fees;
- overall management of the client relationship;
- obtaining information and permissions required for the assignment.
The partner is responsible for ensuring that information supplied to Sienda is accurate and may lawfully be disclosed for the purposes of the work.
7. Fees and payment
Sienda’s fees are agreed directly with the contracting partner.
Unless expressly agreed otherwise, the partner’s obligation to pay Sienda is independent of whether the partner has received payment from its own client.
Payment terms, scope and any additional work will be set out in the relevant proposal, invoice or written agreement.
8. Intellectual property and deliverables
Rights relating to deliverables will be defined by the relevant engagement.
Unless otherwise agreed:
- the partner may use the deliverables for the client and purpose for which they were commissioned;
- Sienda retains its background intellectual property, methods, frameworks and know-how;
- confidential information belonging to the partner or end client remains confidential;
- deliverables may not be converted into unrelated mass-market products or resold repeatedly without written agreement.
9. Data protection
Where an assignment involves personal data, the parties are responsible for complying with their respective obligations under applicable data-protection law.
Additional data-processing arrangements may be agreed where required.
10. Specific engagement terms
Partner engagements can vary considerably.
A proposal, engagement letter, confidentiality agreement, statement of work or other written agreement may therefore contain terms specific to a particular assignment.
Those specific terms will prevail over this general statement where they conflict.
