Comparison · Approaches to AI
Different ways to bring AI into your work. What they actually involve.
AI adoption can follow several paths. This page sets out what those paths look like in practice — their trade-offs, their costs, and what each tends to produce over time.
← Back to HomeWhy this matters
The way AI is introduced shapes what it does to your organisation.
There is no single correct approach to AI integration. What exists is a range of approaches with different starting points, different dependencies, and different consequences for staff, data, and ongoing cost. Understanding those differences before committing to a direction is worth the time it takes.
The comparisons on this page cover three broad patterns we see in practice: purchasing an off-the-shelf AI product and deploying it directly, running a large vendor-led project, and scoping implementation against your actual work before building anything. None of these is universally correct. Each suits different situations.
Side by side
Typical approaches compared.
| Area | Off-the-shelf product | Large vendor project | Structured scoping (our approach) |
|---|---|---|---|
| Starting point | The product's feature set | The vendor's methodology | Your existing work and data |
| Initial cost | Low upfront, rising with scale and add-ons | High; often requires multi-year contract | Fixed per engagement, agreed in advance |
| Fit to your processes | Partial; you adapt to the product | Varies; customisation adds time and cost | Assessed from your data before anything is built |
| Accuracy reporting | Vendor benchmark figures; may not reflect your documents | Depends on contract terms | Measured against your data, failure categories included |
| Human review | Optional add-on or external step | Often reduced or removed | Retained by design where the process requires it |
| Ongoing dependency | Tied to vendor's product roadmap and pricing | Often requires ongoing vendor support | Documented for internal team to maintain |
| Outcome if it does not fit | Discovered after deployment | Discovered after significant spend | Identified during scoping, before costs are committed |
Distinctive elements
What makes the scoped approach different in practice.
Scoping comes before building
We assess whether automation fits your specific work before any system is built. That assessment may well conclude that the process is better handled manually, or that only part of it is suitable for automation. That conclusion costs less than discovering it after the fact.
Measurement is against your data
Performance figures are derived from samples of your actual documents and processes — not from vendor test sets or published benchmarks. Where the system performs poorly on a category, that is reported clearly rather than smoothed into an average.
Human steps are kept where they belong
Every process we work with retains a human review step for items the system cannot handle with sufficient confidence. This is built in from the beginning, not added as a patch when errors appear. Automation handles volume; people handle judgement.
Documentation your team can use
Each engagement ends with written documentation maintained in plain language — not a proprietary system that requires our continued involvement to interpret. Your team should be able to update, extend or hand off the system without returning to us.
Effectiveness
What the research on AI implementation suggests.
On fit assessment
Organisations that assess process fit before deployment report substantially fewer post-implementation revisions than those that deploy first and adjust afterward. The assessment stage is not a delay — it compresses the correction cycle.
On staff integration
Systems designed to work alongside staff rather than replace them show higher sustained adoption rates. When people understand what the system does and does not do, they use it more consistently and flag exceptions more reliably.
On documentation
AI systems without maintained internal documentation tend to become fragile over time as the people who implemented them move on. Documentation written for the internal team, not the implementer, extends useful system life considerably.
Cost and value
What each approach tends to cost over time.
Initial price is one part of the picture. Ongoing subscription costs, support dependencies, internal maintenance burden and revision cycles all contribute to the total cost of an AI integration. The table below summarises the pattern we observe across these dimensions.
| Cost dimension | Off-the-shelf / vendor-led | Structured scoping |
|---|---|---|
| Entry cost | Low to high depending on vendor | Fixed, agreed before engagement begins |
| Recurring cost | Subscription or licence fees ongoing | No recurring licence; internal maintenance only |
| Revision cost | Billed per change or requires new contract | Documentation written so internal team can make changes |
| Cost if unsuitable | Discovered after deployment; sunk cost | Identified at scoping stage, before build cost |
| 3-year picture | Rising as licence and support costs compound | Stable; no dependency on external pricing changes |
Working experience
What working through an engagement looks like.
Typical vendor-led project
-
Scoping conducted by the vendor based on their framework, not your specific workflow
-
Multiple stakeholders and approval layers slow delivery
-
Staff training delivered as a module at the end, often after decisions have been made
-
Ongoing changes require contacting the vendor and entering a change request process
Structured scoping engagement
-
Scoping begins with your documents and records, assessed by us against your actual volumes
-
Defined timeline communicated before the engagement starts; no open-ended delivery phases
-
Staff training conducted alongside implementation, with people who will use the system day to day
-
Documentation handed to your team covers how to make common changes without external help
Long-term picture
What happens to AI systems over time.
An AI system that works well at launch may perform differently two years later as your documents change, your volumes shift, or the people who understood the system move on. The approaches that account for this from the beginning tend to age better than those that do not.
Internal documentation
Systems with documentation written for internal maintenance can be updated by staff who did not build them. This is the single largest factor in whether an AI system remains useful beyond its first year of operation.
Exception handling by design
Systems that route uncertain cases to human review from the start handle change better than those where automation is total. When something new appears in the data, there is already a path for a person to handle it.
No hidden cost dependencies
A system you own and can maintain does not become more expensive when a vendor changes their pricing model or discontinues a feature. That independence has direct value over a multi-year horizon.
Common questions
Things worth clarifying about AI implementation.
"AI can handle everything in the process automatically."
Most business processes contain a proportion of cases that require judgement — ambiguous documents, unusual requests, edge cases the system has not seen before. Automation handles the predictable volume well; the rest needs a person. Systems that do not account for this tend to produce errors quietly rather than flagging them.
"A pilot proves the system will work at scale."
A pilot on a curated sample can demonstrate potential. It does not demonstrate performance on the full range of document types, exception rates at volume, or the effect on the staff who will handle exceptions. These require measurement against representative data before scale decisions are made.
"Newer AI is always more accurate on our documents."
General AI capability improvements do not always translate to better performance on specific document types in specific languages and layouts. Accuracy on your documents is a measurement exercise, not a given. It requires testing against your data, not against a published benchmark.
"AI implementation is mainly a technology project."
Technology is one component. The other components are process design, exception handling, staff understanding of what the system does and does not do, and documentation that survives beyond the project team. Implementations that treat the technology as the whole problem tend to underperform implementations that treat process design as equally important.
Summary
Reasons to consider a scoped approach.
You know what you are getting into
Scoping against your actual data means the decision to proceed — or not — is made with real information rather than an estimate or a vendor's published figures.
Costs are bounded
Fixed-price engagements with no recurring licence costs make the financial picture predictable across a multi-year horizon, which an ongoing subscription model does not.
Your team can maintain it
Internal documentation and training mean the system does not depend on our ongoing involvement. That is a deliberate design choice, not an upsell opportunity.
Honest about limits
If scoping shows the process is not suited to automation, we say so before any implementation cost is spent. That recommendation is part of the service, not a failure of it.
Next step
Talk through what your process involves.
We are willing to look at any process you think might be a candidate for AI handling and give you an honest view of whether it is or not — before any engagement begins.
