How to evaluate a long-term digital delivery partner

Choosing a digital supplier for a longer assignment is a decision with consequences that extend beyond the contract period. A supplier that cannot document its work, does not own its deliveries, or cannot maintain continuity through staff changes can become a source of difficulties that are hard to address mid-delivery. This article describes dimensions that may carry weight in the evaluation.

Stability

The supplier's economic and organisational stability is relevant, particularly for longer commitments. The question is not whether the company is large, but whether it has the conditions to complete the assignment:

• The company's financial situation and history.
• Ownership structure and potential changes.
• Ability to maintain staffing over the contract period.
• Continuity plan for key persons' absence.

Accountability and ownership

A supplier that takes responsibility for its deliveries – rather than simply executing instructions – creates a fundamentally different working relationship. Relevant questions to ask:

• Does the supplier have a named contact person for the entire assignment?
• Does the supplier take responsibility for the delivery as a whole, not just their part of the work?
• How does the supplier handle a situation when something has gone wrong?
• Does the supplier proactively report issues early, or wait for the client to identify them?

Governance and transparency

A transparent supplier creates the conditions for a well-governed delivery. Relevant indicators:

• Does the supplier have a clear and communicated way of working?
• Is status reported on the client's initiative, or proactively?
• Are the supplier's organisation and roles clear?
• Is company information and factual documentation available without requiring an NDA?

Documentation capability

Documentation is what makes a delivery transferable to a third party. A supplier with a weak documentation culture creates lock-in regardless of intent:

• Can the supplier show examples of technical and delivery documentation?
• Is documentation a natural part of the delivery, or does it depend on whether there is "time for it"?
• How is documentation handled through personnel changes?

Continuity

Personnel dependency is one of the most common risks in digital deliveries:

• How does the supplier handle staff changes during an ongoing assignment?
• Is there documentation and process that makes the delivery transferable to a new person or supplier?
• Does the supplier have a continuity plan that does not rely on specific individuals remaining in post?

Competence model

It is worth understanding the nature of the supplier's competence:

• Is the competence internal, or largely based on sub-contractors?
• How is competence maintained through personnel changes?
• Is the competence presented during procurement the same as who will carry out the work?

Collaboration model

A supplier should be workable, not just procurable. How does the collaboration function in practice?

• How are disagreements about requirements or prioritisation handled?
• Is the supplier proactive with information, or reactive?
• How does the supplier communicate risk early, before it becomes a problem?

Information security

Depending on the assignment's nature, information security may be a central evaluation dimension:

• How is access to sensitive data handled?
• What routines exist for personal data management?
• How are information security incidents handled?
• Which security requirements can the supplier meet, and can this be verified?

Maintainability and handover

A delivery that cannot be maintained is a future problem:

• Are the supplier's deliveries sufficiently technology-independent to be maintained by another party?
• Is documentation delivered that makes maintenance possible without the supplier's presence?
• How does the supplier manage handover at the end of the contract period?
