Day 1
You know where you stand
The free discovery session starts the clock. Within days you hold an honest read of your architecture, its risks, and what they are quietly costing you.
Methodology
A delivery methodology built for systems that cannot stop
Agencies quote hours. Lexylon runs a method: agile continuous delivery wrapped around legacy realities, where a CTO can see what Day 1, Day 30, and Day 90 look like before signing anything. The phases below are how every engagement actually unfolds.
What you hold on Day 1, Day 30, and Day 90
Day 30
The design is signed, staging is live
Architecture approved, API contracts defined, and working software running in staging against your real data shapes. Changes are still cheap, because they happen on paper and in staging first.
Day 90
Production, with support already watching
The first workflow runs live behind a measured rollout, and 24/7 support is already monitoring it. From here, delivery is a rhythm, not an event.
The Lexylon Method
Stabilise, design, deliver, operate
01
Technical Discovery & Triage
We audit your existing architecture, map the constraints inside your RPG and legacy estates, and identify the operational bottlenecks costing you money today. Nothing gets recommended until the current state is understood and written down.
Principle: Data Sovereignty & Absolute Integrity02
Secure Architecture Design
The middleware layer is designed, API contracts are defined, and the cloud or on-prem infrastructure is established before a single line of production code is written. Security boundaries and data residency are decided here, where changing your mind is cheap.
Principle: Decoupling & API-First Design03
Parallel Execution
Native mobile apps and web portals are built against staging APIs while your operations continue untouched. We run true agile sprints with working software every fortnight, stress-testing the new interfaces beside the live system.

Managed 24/7 Operations
Deployment is a measured rollout, not a weekend gamble. Production support, DB2 integration monitoring, and fractional technical leadership continue after go-live, with 24/7 cover for the systems that cannot stop.

FAQ
Delivery questions we hear most
How quickly do we see working software?
Every fortnight. Sprints produce working software from the first iteration, and by Day 30 you have real functionality running in staging against your own data shapes, not slideware.
Can our operations keep running during a migration?
That is the point of parallel execution. New interfaces are built and stress-tested beside the live system, and cutovers are parallel run and reversible, so the business never holds its breath.
Do you work agile with our internal team?
Yes, in your cadence or ours. Our engineers join your sprints, boards, and ceremonies when you have them, or bring the structure when you do not. Continuous delivery applies either way.
What happens after go-live?
Phase four never really ends. Production support, integration monitoring, and fractional technical leadership continue for as long as the system matters, with 24/7 cover available.
Can the methodology flex to our budget?
Yes. The phases can be engaged end to end, purchased per module, or run as capacity beside your own team, under any of our three engagement models, with every estimate built transparently from effort in hours.
Engagement models
Three ways to engage, one transparent cost structure
The method flexes to the budget: phases can be engaged end to end, per module, or as capacity working beside your own team.
Dedicated team
A stable squad of Lexylon engineers reserved for your roadmap, month after month. Predictable capacity, a predictable invoice, and a team that compounds knowledge of your business.
Time and materials
Pay only for the hours worked, at some of the most competitive rates in the Australian market. Ideal when scope moves, with timesheets you can read and question line by line.
Project or module based
A fixed price built up from an honest effort estimate in hours, module by module. You see exactly how the number was reached before you sign, and it does not move unless the scope does.
