For most organisations trying to turn a continuing stream of business and AI ideas into working changes, a Business Improvement Factory is the stronger model. Hire a developer when you have a stable, full-time technical backlog and the leadership to direct them. Use a software agency when you have one substantial, bounded project. Use a Business Improvement Factory when improvement itself is ongoing.
These are not three equal versions of the same service.
A developer is a person. An agency is a project team. A Business Improvement Factory is the operating capability that continually finds, prioritises and implements the right changes.
It can use developers, agencies and AI agents when they are the right production resource. The difference is that the Factory connects each build to the organisation's strategy, context and accumulated learning.
You do not have to build that capability from scratch. Busy Work provides the platform, Business Blueprint, strategists, developers and AI agents needed to start with one useful improvement and expand from there.
The short answer
| Hire a developer | Use a software agency | Use a Business Improvement Factory | |
|---|---|---|---|
| What you buy | The capacity and skill set of one employee | A temporary team assembled around a project | A continuing system for turning business needs into working changes |
| Best fit | A stable backlog inside a core product or system | One large, well-bounded product or transformation | An ongoing portfolio of product, workflow, reporting, agent and operational improvements |
| Hidden requirement | Product leadership, technical direction, recruitment, management and enough work of the right kind | A stable brief, discovery time, procurement, stakeholder access and clear ownership after handover | Leadership support, business goals and people willing to improve how work gets done |
| Time to useful capacity | Begins after hiring and onboarding | Begins after scoping, contracting and discovery | Can begin with one scoped improvement and build context while delivering |
| Cost exposure | Ongoing fixed employment cost, whether the work matches the developer's skills or not | Project overhead, discovery, change requests and repeated commercial scoping | Flexible implementation spend matched to the value, complexity and risk of each change |
| Range of skills | Limited by the person or internal team hired | Broad during the contracted project | Flexible across strategy, product, data, automation, agents and development |
| Small-change economics | Small jobs compete with the core backlog | Often too small to justify project overhead | Designed to make repeated small improvements viable |
| Organisational context | Often concentrated in the employee | Reconstructed for each engagement and weakened at handover | Accumulated in a living Business Blueprint and reused for future work |
| What happens next | More work joins the same backlog | A new scope or project usually begins | The result, feedback and new context make the next improvement easier |
| Main risk | A new bottleneck forms around one person or team | The business moves before the project delivers | The organisation treats the Factory as a request queue instead of connecting it to strategy and outcomes |
The familiar options feel simpler because organisations already know how to buy them. That does not make them a better fit for the work.
The real question is whether you have one stable body of technical work, one defined project, or a continuing stream of ways the business could be better.
Why the usual choice is often the wrong one
Most organisations do not have one software problem.
They have hundreds of smaller problems, ideas and points of friction spread across meetings, customer feedback, business data and people's heads.
They need a report for a decision. A product journey needs one small intervention. Two systems do not communicate. An internal workflow depends on copy and paste. A team wants an agent to take on repetitive work. A customer complaint reveals a product improvement. A new constraint blocks several useful ideas at once.
Your people know where the business could be better. They lack the capacity to do something about it while keeping the business running.
Hiring a developer or commissioning an agency can increase production capacity. Neither automatically solves this wider problem.
The organisation still needs to decide what matters, recover the relevant context, shape each request, choose the right implementation method, manage risk, test the result and learn from what happened.
That is the job of a Business Improvement Factory.
When hiring a developer is the right choice
Hire a developer when all or most of the following are true:
- software is your product or a core source of competitive advantage;
- you have a sustained, predictable backlog of technical work;
- the work requires deep and continuing knowledge of one codebase or system;
- you already have product and technical leadership;
- you can support architecture, security, quality, deployment and maintenance decisions;
- and there is enough suitable work to justify permanent capacity.
In this situation, internal ownership and accumulated technical knowledge are valuable. The developer can work closely with customers and colleagues, learn the codebase and contribute over a long period.
The costs and trade-offs of hiring a developer
The salary is only one part of the commitment.
The organisation also takes on recruitment, onboarding, management, equipment, tools, leave, professional development and the risk that the work does not consistently match the person's skills.
One developer cannot be equally strong at product discovery, data engineering, interface design, browser automation, AI agent development, security and organisational change. When the demand changes, the capacity does not automatically change with it.
The person can also become a new bottleneck. Requests from across the business join one queue. Urgent fixes compete with maintenance. Poorly shaped ideas consume development time. Important context sits in one person's head.
Most importantly, a developer is not an improvement system.
They can implement what reaches them. They do not automatically give every employee a low-friction path from seeing a problem to getting the right change working. They do not establish strategic priorities, delegated budgets, acceptance criteria or measurement simply by being hired.
If you need one full-time technical profile, hire it. If you need an organisation-wide way to turn many different kinds of ideas into results, a single hire is too narrow.
When a software agency is the right choice
Use a software agency when:
- there is one substantial outcome with a reasonably clear boundary;
- several disciplines are needed for a defined period;
- the work benefits from a coordinated project team;
- the organisation can provide decisions and access during discovery;
- and ownership after handover is clear.
This can suit a new customer product, a major platform replacement, a complex integration or a significant redesign.
The agency assembles product, design, development, quality, architecture and delivery skills without the client hiring every role permanently.
The costs and trade-offs of a software agency
An agency needs to understand enough of the organisation to deliver safely. That usually means discovery, stakeholder meetings, documentation, commercial scoping and project management before the result reaches real work.
Those activities can be sensible for a large build. They overwhelm the economics of a small one.
Every new request can trigger another round of briefing, estimating, approval and contracting. Changes discovered during delivery may become change requests. Context reconstructed for one project may be lost when the team moves on. The client then pays to explain the organisation again during the next engagement.
The commercial model also naturally favours larger projects. An agency has little incentive to mobilise a multidisciplinary team for a series of $150 fixes, even when those fixes would create meaningful cumulative value.
There is a timing risk too. The business may change while the project is being defined and delivered. A report required for a current decision, a customer problem affecting retention now or an experiment based on rapidly changing AI capability can lose much of its value during a long project cycle.
Use an agency when the work is genuinely a project. Do not turn a continuing portfolio of improvements into an endless series of projects.
When a Business Improvement Factory is the stronger model
A Business Improvement Factory is designed for the reality that improvement never ends.
It is the better fit when:
- valuable ideas come from many people and parts of the business;
- the work ranges from small fixes to larger strategic builds;
- internal teams are busy keeping core operations moving;
- different requests need different technical skills;
- speed affects whether the result is adopted;
- organisational context should accumulate rather than being recreated;
- and leadership wants improvement to become a permanent operating capability.
The Factory does not begin by asking the organisation to design a new department or fund a transformation programme.
With Busy Work, it begins with a useful business change.
The platform captures the request. The Business Blueprint supplies relevant organisational context. The Dispatch Assistant looks for related work and helps shape the specification. Budgets and risk thresholds determine the approval path. The right combination of strategists, developers and AI agents implements the change. The user tests the result in real work. What happened becomes part of the context used for the next decision.
That is a concrete service, not an abstract aspiration.
A Factory is easier to start than it sounds
The buyer does not need to recruit a team, select a complete technology stack and document the whole organisation before seeing value.
Busy Work provides the initial production capability and captures the required context progressively. A team can start with its goals, tools, data sources and one important workflow. The Blueprint grows as real improvements are implemented.
This matters because large upfront transformation programmes delay proof. A Factory should demonstrate the new way of working while it is being established.
The first 30 days should create clarity, build confidence and put useful wins on the board. The capability then expands from where there is support.
AI changed the minimum economically viable improvement
Traditional software economics favoured a small number of large projects.
Every change carried the cost of briefing, coordination, specialist labour, testing, deployment and maintenance. Small workflow problems and customer paper cuts remained untouched because the machinery required to fix them cost more than the individual issue appeared to justify.
AI can now assist across research, analysis, specification, coding, configuration, testing, documentation and coordination.
This does not make coding free or remove the need for expertise. Research results depend heavily on the task and context. In one controlled experiment, developers using GitHub Copilot completed a defined coding task 55% faster. In a separate randomised trial, experienced open-source developers working in familiar mature repositories took 19% longer with the early 2025 AI tools being tested. (GitHub; METR)
The relevant shift is not that AI always makes every developer faster.
It is that an experienced, AI-enabled implementation team can now make a much longer tail of useful business changes economically viable. The organisations that benefit will be those with an operating model capable of finding, governing and absorbing those changes.
The long tail does not fit traditional delivery models
A directional review of close to 3,000 Busy Work requests over a little more than five months found:
- around 60% required less than $200 of build effort;
- a further roughly 20% required between $200 and $1,000;
- and work ready to use within five days was around three times more likely to reach production than work that took longer.
These are approximate operating figures, not the result of a controlled academic study. They match a pattern we have written about before: small AI builds get adopted faster.
They still reveal an important structural mismatch.
Around 80% of the observed requests sat below $1,000 of build effort. A permanent hire is difficult to flex across such a varied portfolio. An agency's project machinery is expensive relative to each request. Yet leaving the work undone allows friction, missed decisions and customer problems to compound.
A Factory groups the demand into one managed improvement system. It applies proportionate briefing, approval and implementation effort to each change while preserving the relationship between them.
The unit of value is not the size of the project. It is the business result created relative to effort, delay, risk and ongoing burden.
What this difference looks like in practice
A dashboard for a decision with a short shelf life
In one organisation, somebody suggested analysing the last actions customers took before becoming dormant in a product.
People agreed that it was a good idea, but it belonged to no project and had no owner. Months passed before a senior sponsor helped it reach the data team. The analysis identified four common exit points, but the organisation still lacked development capacity to test interventions.
The report itself required only a few days. The organisation lost months to ownership, queues and coordination.
An agency could have turned the idea into a defined analytics project, but the overhead would have been disproportionate. A developer could have built the report if it reached the top of their backlog, but the organisation still needed a way to capture, prioritise and carry the idea through to experiments.
In a Factory, the question can move through analysis, implementation and measurement while its context is still valuable.
This is a perishable improvement. Delay does not simply postpone its value. Delay can destroy it.
A temporary bridge between legacy systems
An HR employee spent two days each month moving information between two systems with no APIs. Both systems were expected to be replaced. A permanent integration was quoted at around $15,000.
Busy Work created a browser-using agent in an afternoon. It performed the transfer through the employee's existing access. The employee checked early results and helped train the agent around exceptions over time.
Hiring a developer for this problem would make no sense. A conventional integration project could cost more than the temporary problem justified.
The right response was transitional automation: a controlled bridge whose cost and lifespan matched the need.
The implementation also changed how the employee saw the work. Within a week, they identified several other tasks where agents could help. One small result increased both capacity and organisational AI literacy.
A stream of internal paper cuts
One missing field, repeated copy-and-paste step or customer-specific screen may never justify a hire or agency project.
If the organisation sees hundreds of them, the problem is not that each lacks a business case. The problem is that the organisation has no production system designed for small changes.
That is where the Factory has the clearest advantage.
The Factory chooses the right production resource
Using a Business Improvement Factory does not mean rejecting internal developers or agencies.
It puts them in the right place.
The Factory can route work to:
- an internal developer for changes deep inside a core product;
- a software agency for a substantial multidisciplinary programme;
- an automation specialist for a complex integration;
- a product partner for a customer-facing experience;
- or Busy Work's AI-enabled build team for rapid product, reporting, agent and workflow improvements.
The Factory retains the layer that a staffing or project purchase does not provide on its own:
- strategic priorities;
- organisational context;
- low-friction intake;
- specifications;
- governance and approvals;
- acceptance and measurement;
- and accumulated learning.
The decision is no longer which supplier model the organisation must use for everything. It is which production capability is right for each improvement.
How to make the decision
Hire a developer if you can say yes to all four
- We have sustained, predictable work for this technical profile.
- The work sits inside a core product or system that needs deep internal ownership.
- We have product and technical leadership capable of directing the role.
- Permanent fixed capacity is more useful than access to varied skills.
Use a software agency if you can say yes to all four
- We have one substantial, bounded outcome.
- The brief is stable enough to manage as a project.
- We need several disciplines for a defined period.
- We know who will own the result after handover.
Use a Business Improvement Factory if any of these are true
- Our people continually see problems and ideas that do not reach implementation.
- Valuable work ranges from very small fixes to larger builds.
- The right implementation skill changes from request to request.
- Our internal teams are too busy delivering core work to improve the systems around it.
- We repeatedly lose context between discovery, briefing, implementation and handover.
- We want every result to make the next improvement faster, safer and more valuable.
For organisations adopting AI across their operations, the third list is usually the most accurate description of the demand.
Frequently asked questions
Do we have to build the Business Improvement Factory ourselves?
No. Busy Work provides the platform, Business Blueprint, Dispatch Assistant and flexible strategy and implementation capability. You can begin with one improvement in one team, then expand as results and support grow.
Is a Business Improvement Factory a replacement for developers?
No. Developers are an important production resource inside the Factory. The Factory makes sure they receive better-prioritised, better-specified work and are used where their skills create the most value.
Is a Business Improvement Factory a replacement for software agencies?
Not in every situation. A strong agency can be the right resource for a large bounded build. The Factory prevents every business need from being forced into an agency project and preserves context before, during and after an engagement.
Is a Factory cheaper than hiring a developer?
The comparison depends on the work. A permanent developer can be economical for stable, full-time demand inside a core system. A Factory is better suited to an uneven portfolio requiring different skills, priorities and levels of effort. It also supplies the intake, context, governance and learning system that a hire alone does not.
Is a Factory cheaper than a software agency?
For a continuing stream of small and medium improvements, it can avoid repeated discovery, scoping and project mobilisation. For one large, stable and specialised project, an agency may still be the most economical production choice.
Does every request get built?
No. The Factory connects requests to strategic goals, expected value, implementation effort, risk and existing organisational constraints. It gives people a path to propose improvements without turning the organisation into an uncontrolled request queue.
Can we start with one team or process?
Yes. The Factory should begin where there is leadership support and a real mandate to improve. One team, department, product or process can establish the context, trust and operating rhythm before the model expands.
Bottom line
If you have one stable technical backlog, hire a developer.
If you have one substantial, bounded project, use a software agency.
If your people continually see where the business, product or service could be better, do not solve a portfolio problem with a staffing or project purchase.
Use a Business Improvement Factory.
Busy Work gives you the platform, organisational context and implementation capacity to start with one useful change, keep the day-to-day work moving and build a business that gets better at getting better.
