Application intelligence
Understand your existing software, document how it works and plan how to change it.
What is Wayfinder?
Wayfinder is Harten’s software intelligence platform. It examines an application’s source code (the instructions developers wrote), alongside available database definitions, configuration, tests and technical documents. It brings the findings together so your team can understand how the application works without having to reconstruct everything from memory.
That includes the business rules the software applies, the information it stores, the systems it connects to and the processes it supports. Harten carries those findings into documentation, a description of the behaviour a replacement may need to preserve, and a proposed modernisation plan.
You can use that material to understand an unfamiliar system, prepare a handover, challenge assumptions in an existing programme or scope the work before choosing a replacement.
What your team receives
Application specification
A structured description of current behaviour and candidate requirements. Your specialists can confirm which behaviours should be preserved and which should change.
Modernisation plan
Proposed changes, work packages, dependencies, delivery sequencing and verification activities, with the decisions your organisation needs to make.
Where your specialists contribute
Source code can show how a rule is implemented, but not always whether the business still needs it. It can reveal a connection to another system without proving that the connection is still used. Wayfinder records these questions. Harten works with your business and technical specialists to confirm the intended behaviour and identify any further evidence needed. Questions that remain unanswered stay visible.

DEFRA PRSD-IWS: International Waste Shipments
Harten analysed 423,897 lines from the publicly available DEFRA / Environment Agency application. You can read the application documentation, explore the specification and inspect the modernisation plan, including its delivery schedule and known gaps.
This is independent analysis of public source code, not a DEFRA-commissioned engagement or an endorsed modernisation plan.

Source analysis, documentation, nine supporting views, a recovered specification and a modernisation plan, followed by customer review and agreed validation.
Fee agreed after scoping
Four-week engagement. We confirm the source, scope, review allowance and timetable before starting.

Application knowledge remains useful beyond a modernisation project. When your source changes, Harten can scope a refresh of the documentation and related findings. Continuous documentation that automatically identifies affected material and proposes updates is in development; automatic continuous operation is not yet implemented.
How Wayfinder analyses the source
Wayfinder uses AI-assisted reasoning to examine code paths, conditions, data changes and dependencies across the application. For example, finding a payment calculation is different from understanding when it runs, which records it changes and which other processes rely on the result.
Findings retain supporting source references and distinguish observations from inference. This does not mean that every conclusion is formally proved or that source analysis replaces operational testing and customer approval.
New product in development
Wayfinder CSI: Continuous Systems Intelligence
Harten is developing a separate service to connect application documentation, specifications and supporting evidence with vulnerability, deprecation and support information. The proposed graphs would show which components and business processes a finding affects, and what needs checking before a change.
