AI agent development for real business work

Agents that connect knowledge, tools and business rules—designed with evaluation, permissions, human approval and fallback from the start.

WHO IT IS FOR

For teams working across multiple information sources or multi-step tasks that a question-answer chatbot cannot complete.

OUR APPROACH

Define the outcome, scope and acceptance criteria before choosing technology, so the investment solves a real problem and remains maintainable.

PROBLEM

Problems to solve before adding another tool.

OUTCOME

What the project should make better.

  • A use case with measurable success criteria
  • An agent connected to only the knowledge and tools it needs
  • Human approval, fallback and audit history
  • Evaluation and monitoring before broader autonomy
USE CASES

Useful scopes shaped around the work.

01

Knowledge Assistant

Find and summarise authorised information with source references.

02

Sales Assistant

Qualify needs, prepare context and hand the opportunity to a person.

03

Document Processing

Extract, classify and route documents for human verification.

04

Research & Operations Agent

Gather across systems and prepare a governed action.

WORKFLOW EXAMPLE

Example: an AI agent prepares a sales response

Follow a question through approved information to a draft reviewed by the sales team before it reaches a customer.

  1. 01

    Receive the brief

    Check the question and permission to use the input.

  2. 02

    Find approved information

    Retrieve service facts and identify missing evidence.

  3. 03

    Request human review

    Draft a response and questions for the team to check pricing, conditions and accuracy.

  4. 04

    Hand off and record

    Pass the reviewed draft into the agreed workflow with status and an action history.

Explore sample input and expected output

Sample input

Sample: a prospect needs a bilingual company website, has existing content and wants editing access. Layout count and integrations are unknown.

Expected output and review

A sourced summary and questions about layouts, CMS and timing. Sales estimates the scope and checks the response before sending; unavailable information is escalated.

An illustrative scope example. Integrations and acceptance tests follow each business’s data and permissions.

SYSTEM THINKING

An agent architecture designed for useful control

Connections, permissions and failure states are designed alongside the interface, so a simple front end does not hide operational risk.

DELIVERABLES

Deliverables that can be accepted and operated.

01

Use-case workshop and risk assessment

02

Knowledge, tool and permission architecture

03

Prototype with real workflow samples

04

Evaluation, guardrails and human handoff

05

Deployment, logging and improvement plan

SCOPE & INVESTMENT

Project scope and pricing inputs

Investment includes solution design and development, integrations and recurring model or platform usage. Data quality, risk and evaluation needs usually matter more than the number of screens.

  • Data volume and quality
  • Tools, APIs and permissions
  • Accuracy and evaluation criteria
  • Model usage, monitoring and support
ACCEPTANCE & OPERATION

Acceptance and operating costs

Project acceptance criteria

  • Evaluate representative tasks against agreed expected behaviour
  • Restrict tools and data to authorised permissions
  • Require approval for consequential writes and stop at resource limits

Ongoing costs to itemise in the proposal

  • Usage-based model/API and connected-tool fees
  • Evaluation and knowledge-source maintenance
  • Monitoring, permissions and workflow changes

Test coverage and operating responsibilities are agreed for the project before work begins.

From scope to acceptance and handover

01 /

Understand

Discuss goals, audiences and constraints to define a useful scope.

02 /

Design

Make structure and interactions clear before development begins.

03 /

Build & test

Develop the system and test critical journeys across real devices.

04 /

Launch & support

Launch, share documentation and use evidence to guide improvements.

Agree test cases, reviewers, account ownership and support before work. Test critical journeys with approved data before launch.

FAQ

Questions before the work begins.

How is an AI agent different from a chatbot?

A chatbot usually responds. An agent can use data, call tools and continue through several steps, which requires stronger permissions, approval and monitoring.

Can an agent connect to LINE or company systems?

Yes when those systems expose a suitable API or integration path. We review LINE OA, CRM, Google Workspace, databases and internal systems before defining the workflow.

How do you reduce incorrect answers?

We constrain sources and tools, validate outputs, build evaluation sets, log activity and escalate when confidence or policy requires a person. No approach guarantees 100% accuracy.

What determines AI agent development and running costs?

Estimate tasks, knowledge sources, tools, permissions and evaluation work. Separate development from model/API usage, hosting and knowledge maintenance. Begin with a scoped pilot, pass criteria, human approval points and usage limits before expanding.

NEXT STEP

Have a problem worth scoping clearly?

Share the context, outcome and systems involved. We will help identify the questions to answer before investing.
