The ARENA 414 model

Your commercial engine has three zones.
Growth leaks in one of them.

Industrial growth does not leak at random. ARENA 414 orders it across 9 phases and 3 zones: before, during and after conversion. BARRO audits all 9 to locate where the growth leaks are — in windows and façades, between architect and carpentry transformer.

BEFORE ZONE · 4 phases

Build judgement with the architect.

F1. From ghost to visible
F2. When the pain stings
F3. Owner of the category
F4. When the project calls

Exist on the architect's radar before the bid. Put a name to the technical problem (U-value, solar factor g, energy regulation). Be a serious default option. Enter the spec before the competing system maker.

CONVERSION ZONE · 1 phase

Close a healthy and executable yes.

F5. The battle of the yes

The moment when what was built before is confirmed or lost. If the yes is poorly closed (forced discount to the carpentry, deadlines outside the site schedule), everything that follows gets complicated.

AFTER ZONE · 4 phases

Capture carpentry and façade cross-sell.

F6. The moment of truth
F7. From option to habit
F8. The expansion machine
F9. Evangelisation

On-site delivery without incidents. Carpentry network as active series-type prescription. Cross-sell into light façade and technical glass. Architect who specifies you again.

A model in three layers of depth.

First, a no-cost preliminary diagnosis identifies the main leak signal in 15 minutes. Then, a 7-week Full ARENA Audit contrasts the diagnosis with management interviews, internal documentation, operational evidence and specialist auditors. Finally, the continuous audit turns the analysis into monthly governance: own platform, recurring opinion, dedicated auditor and growth plans.

Level 3 · Continuous Governance
Growth Governance

A monthly system to govern growth with the BARRO audit team working permanently alongside management and internal teams. Each month the Score is updated, a signed opinion is issued and active leaks, real progress, setbacks and pending decisions are reviewed.

The work converts each leak into an execution agenda: what needs correcting, who must do it, with what priority, what capability is missing and what evidence will demonstrate the gap is closing. When the company needs external support, BARRO activates, coordinates and supervises specialist partners to ensure the solution is executed with rigour.

The BARRO HUB platform supports the monitoring with monthly Score, sector benchmark, Client Voice, What If scenarios and a live roadmap. It is not a one-off recommendation or a recurring report: it is a governance cadence to measure, correct and accelerate growth every month.

How the Score ARENA Express works.

A first reading to orient growth priorities. In under 15 minutes, ARENA 414 calibrates responses by sector and revenue band to identify a first leak signal — no integrations, no meetings, no commitment.

01

Access the online questionnaire

No prior registration. Enter the company, select sector and revenue band, and start the 15 questions.

02

Responses calibrated by sector

Each answer feeds the ARENA 414 engine, calibrated by sector and revenue band. The system applies the same analytical framework as the Full Audit, in preliminary form.

03

Analysis and leak detection

The engine processes the answers against the ARENA model and generates scores per phase. It identifies the main leak, the structural archetype and the maturity level of the growth system.

04

Result in under 15 minutes

You receive your ARENA Score, the detected archetype and the main leak with a permanent URL. If it makes sense to continue, we propose the signed Full Audit with the 3 leaks and closing plan.

The ARENA 414 system.

ARENA 414 is BARRO's proprietary framework for auditing and governing industrial growth. It structures the commercial engine of B2B manufacturers across 9 phases in 3 zones, under a 4-1-4 logic: four phases before conversion, one conversion phase and four subsequent phases. It evaluates 45 sub-dimensions, identifies 20 leak archetypes and connects the diagnosis with over 700 prescriptive actions, calibrated against 379 manufacturers in 12 sectors. Each phase has its own scoring, sector threshold and specific battery of actions — in windows and façades, calibrated to the architect and carpentry network.

For whom

Industry only.

BARRO is designed for B2B industrial manufacturers between 5 and 80 million euros. Only companies where growth depends on technical sales, industrial cycles and productive capacity.

01Automation and roboticsScope creep in integration projects: margin can drift from 47% initial to 18% final. 02Electrical material and constructionThe buyer often reaches the first meeting with much of the decision already made. 03Logistics and transportThe handoff between sales and operations often becomes the bottleneck blocking repeat business. 04Public works and miningThe tender is the finish line, not the start: the opportunity may be decided during engineering. 05HVAC and climate controlAftermarket often emerges as a second business: a margin engine many manufacturers fail to capture. 06Metal industryBids can be lost before price even comes up. Win rate often drops to ~20% without prior diagnosis. 07Plastic industrySilent churn: deterioration can accumulate for months before showing up in the report. 08PackagingMediocre technical content can weigh more than publishing nothing. Authority is often decided on the manufacturer's website. 09AgroindustrySmall retention points can be worth far more than large acquisition campaigns. The leak appears in repeat business, not new sales. 10Automotive and aviation componentsExtensive buying committee: the internal sponsor may decide before the technical evaluator.
11Windows and enclosuresA poor delivery can cost the next contract. After-sales acts as the new pre-sales.
12Food industryClosing discounts can cost several times more in EBIT than negotiating a non-price term.

Why BARRO and not a consultancy, an agency or a dashboard.

Consultancies leave with the PowerPoint.

They run a one-off project, present to the board, get paid and disappear. Two years later the problem is still there with no verification of whether the recommendations were executed.

Agencies optimise levers. Not the whole system.

They optimise digital campaigns, set up a CRM, build a new site. In windows and façades, no one audits from outside prescription with architecture studios, the activation of the carpentry transformer network, or range cross-sell into façade and technical glass.

Dashboards give data without diagnosis.

Knowing the data is not knowing what to do with it. BARRO signs a monthly opinion with human interpretation by a senior auditor, not just another radar with metrics without reading.

What is worth clarifying before moving forward

How do you enter the architect's spec before a competing system house locks the solution?
We do not enter for you: we audit what you are missing to enter. Phases F1 to F3 (editorial visibility, activated pain, category authority) explain the bulk of the problem when a third-party system appears in the bid before yours. The opinion identifies whether the prescribing architect does not remember you because of an absence of technical presence in journals and training, because of insufficient U-value and g-value documentation against the project, or because your system house is not listed in the technical office's calculation tools. Each hypothesis has a distinct set of actions.
How do you measure whether the network of window fabricators actively prescribes rather than merely fabricates?
Three combined metrics: share of fabricators who have ordered at least one system in the last 6 months, ratio of projects referred per fabricator-month, and cross-sell rate towards higher tiers (from basic window to thermal-break range, lightweight facade or low-E glass). Phase 7 evaluates whether the network operates as a passive distribution channel through 1,000-plus fabricators or as a prescribing force with judgement before the end client and the on-site installer. The difference shows in margin, not in profile volume shipped.
How do you use energy efficiency (building energy code, EPBD, Passivhaus certification) as a real commercial differentiator?
The sector meets CE marking and EN 14351-1 as a minimum requirement, but few manufacturers convert this into a structured commercial argument. We audit whether your team translates U-value, g-value and Passivhaus certification into value conversations with the architect and the developer, or whether they leave it on a technical sheet that nobody reads. The difference between meeting code and prescribing code is F2 (activated pain in the prescribing architect) and F3 (recognised technical authority).
How much weight do NextGenerationEU renovation grants carry in today's commercial engine?
A great deal, and for a short time. Residential renovation driven by European funds has shifted the centre of gravity from new residential to envelope replacement in the existing stock. If your engine is calibrated for new construction through traditional fabricators, you are missing the cycle. We audit commercial coverage of property managers, presence on technical renovation platforms and capacity to respond to grant deadlines. When the programme ends, the advantage will be held by whoever built the network during the wave.
What do you need from my team to start the Score Express at no cost?
Four one-hour interviews with general management, sales, marketing and operations. Minimal documentation of your commercial engine (team structure, product range across PVC, aluminium, wood-aluminium composite windows, curtain wall or technical glass, main residential and commercial markets, network of active fabricators). No need to connect a CRM or integrate anything. We organise it within a single week.
How long until the business sees impact, given the 6-12 month construction cycle?
It depends on the detected archetype and the segment. In conversion and closing patterns (zone F4-F5) on short residential projects, results show in 90-180 days. In retention and cross-sell patterns (zone F6-F9) in commercial and singular projects, the cycle is 12-18 months because of project duration. In visibility and prescription patterns before the architect (zone F1-F3), 18-24 months, aligned with the next generation of projects in the practice's pipeline. That is why we recommend continuous audit: measuring progress month after month avoids decisions based on a single snapshot of the construction cycle.
How does BARRO differ from an energy audit firm or a financial audit firm?
A financial audit reviews past accounts. A building energy audit reviews technical compliance (building energy code, certification, U-values, testing). BARRO audits the future system: how the commercial engine is producing (or not producing) growth. Zero methodological overlap. The financial audit looks at the balance sheet; the energy audit looks at the envelope of the finished building; we look at the system that connects your company to the prescribing architect, the technical office, the window fabricator, the developer and the end client.
