Choose the delivery model that can understand the buyer, implement the work and maintain accountability. Team size alone does not settle those questions. A capable freelancer, an agency and an internal specialist can each be the best choice for a different operating situation.

| Decision | Freelancer / consultant | Agency / specialist team | In-house |
|---|---|---|---|
| Strategy accountability | Often direct access to the person doing the diagnosis | Confirm the actual strategy owner and client lead | Embedded owner with access to commercial context |
| Implementation | May implement directly or require your developers | Can combine skills; verify what is included | Depends on internal engineering/content capacity |
| Expertise | Depth in a narrower area; seek help for gaps | Several disciplines if the assigned team has them | Strong business knowledge; outside help for specialist tasks |
| Coordination workload | You may coordinate other suppliers | Provider can coordinate, with clear approvals | Management, hiring and cross-team prioritization stay internal |
| Continuity | Agree absence, handoff and documentation arrangements | Ask who covers personnel changes | Account for recruitment, turnover and training |
| Total cost | Fee plus tools, writing/development and your coordination | Fee plus exclusions and internal review time | Salary, benefits, recruitment, tools and supporting teams |
When an individual specialist is preferable
A focused investigation, senior strategy review or limited page pilot can suit a specialist when you already have implementation support. Direct communication can make a small scope efficient. Check whether the person can do the technical work or needs your team to translate recommendations into changes.
Agree how decisions, source files and access are documented. If one person is unavailable, you should still own the accounts and understand the state of the work. A continuity plan matters even when the working relationship is excellent.
When a team or agency is preferable
A continuing programme that needs research, writing, design, development and reporting may benefit from coordinated specialists. Ask who actually works on your account, how senior review happens and what capacity is assigned. A broad service menu is not proof that each discipline is included in your proposal.
For an urgent migration, the provider must be able to coordinate with your launch team and validate changes. Ask about release responsibility and escalation rather than assuming a larger team eliminates launch risk.
When to build in-house
In-house ownership can fit a sustained backlog with frequent product, compliance or commercial decisions. An internal specialist can develop deep context and influence priorities every day. They still need technical, content and subject-expert support; a single hire is not an entire implementation department.
It may be sensible to retain internal strategy and measurement ownership while purchasing an external migration, technical investigation or specialist production scope. That hybrid model can preserve knowledge without asking one hire to cover every discipline.
How Strata’s model fits
Dean leads strategy, client accountability and final review from the Philippines. Scoped specialists can support research, production and implementation. Engineering is part of the capability, and the proposal specifies who changes the site. That model can fit buyers who want a senior accountable specialist with a practical delivery path.
It may not fit a buyer who needs a full-time employee embedded in the office or a large simultaneous production operation under one internal department. Discuss workload, timing and access before deciding.
