Rextuvia finds the lost value

Field

On paper

On paper the process is simple, linear, and known. From supply chain and inventory to finance, compliance, and product design, every department has its ways of working.

Basis A simple purchase-to-pay procedure

Reality

Reality normally looks different. Deviations, workarounds, rework, approvals going back and forth, bottlenecks and delays are some of the many defects found in a process.

Basis The same procedure as systems record it; a schematic, no single company’s log

Process mining

Systems keep a record of every action: which process, what activity and when it happened.

Process mining is a scientific field, begun in 1999. It compares the process as designed with the process as the systems recorded it. The largest companies run it on dedicated platforms; Celonis, one of them, reports about half of the top 200 of the Forbes Global 2000 among its customers.

Findings uncover defects that are traceable down to the record, so an organization can see where and how exactly it leaks value and money.

Method

Deliverable

No licences, no training, no integrations to maintain.

One engagement report

Defect report. Where the process breaks down and why, each defect traced to the system’s records.

Value lost. What each defect costs: profit lost every year, profit recovered once, cash released once.

Recommendations. What to fix, defect by defect.

Scope

Purchase-to-pay and order-to-cash. The two processes that touch every supplier, every customer and every invoice. Other processes a system records, such as inventory management, production, record-to-report or asset maintenance, can be added to a Project or to Monitoring, each quoted on effort.

The data comes from an enterprise resource planning (ERP) or internal operational system, under a non-disclosure agreement (NDA) and a data processing agreement.

Nothing to install. A data extract is transferred from SAP, NetSuite, JD Edwards, Microsoft Dynamics or other ERP systems.

Framework

Projects succeed or fail on the quality of the data behind the event log, so the framework starts with a Pre-audit: a free check of the tables before any commitment, covering which systems, which fields, how far back and how clean.

Event log. The raw tables of the ERP system become one log: each order, each step, each timestamp.

Discovery, conformance and enhancement. The process is drawn from the log, held against the agreed reference model so every deviation is named, then enhanced with the times and volumes behind each path.

Value assessment. A price for each defect, agreed together and applied to every case found.

The report. One report in three parts: defect report, value lost and recommendations to recover the leaked value.

Project tiers

Pilot. Purchase-to-pay. 12 months of data. One site, the largest or most troubled.

Project. Purchase-to-pay and order-to-cash. 24 months of data: the last 12 measured, the 12 before them to show which defects are structural. Across every location on one ERP instance.

Monitoring. After the Project, the same scope, repeated every six months or once a year on new data.

Provenance

Where the figures come from, and where Rextuvia does.

Every figure on this site and in every deliverable carries three things: an evidence grade, a named source and the basis it was computed on. A number that cannot say where it came from does not appear. The same rule applies to the firm.

The founder

Estevão Castro, Founder. TK: two sentences on the record behind the firm, written from the model CV when it exists.

How Rextuvia works

Delivered from a Portugal cost base for companies in the United States. Open-source process mining tooling, used internally; no platform is sold or hosted.

Pre-audit

Start with the data, not with a contract.

The pre-audit is free and comes before anything is signed. Rextuvia reviews which systems hold the process, which tables and fields exist, how far back they go and how clean they are, and returns a written view of what a Pilot or a Project could and could not find.

This sketch does not send. On the live site the request goes to TK@rextuvia.com.

What Rextuvia asks for

Read access or an extract of the tables behind the processes in scope, under an NDA and a data processing agreement. The list of tables is TK and will come from the extraction plan.
