How to Use Installed Base, Equipment Age, and Maintenance Model in an ICP

Who this guide is for

This guide is for equipment manufacturers, component and spare-parts suppliers, retrofit providers, maintenance-service firms, and exporters whose offer depends on what is already installed at a facility. It is especially useful where a target industry contains both modern and legacy plants or where maintenance responsibility sits outside the asset owner.

1. Define the installed-base question

An installed base is not simply “old machinery.” For ICP work, define it as: The bounded population of relevant assets operating, stored as active spares, or maintained for service at a specified facility on a specified date. The definition needs five fields: Field Required decision Asset family Which models, technologies, capacities, and configurations count? Geographic boundary One site, a business unit, a region, or the enterprise? Unit Individual machine, line, cell, system, or installed capacity? Status Operating, standby, mothballed, decommissioned, or Unknown? Evidence date When was the population last verified? Official economic data provides context, not a named-account inventory. The Bureau of Economic Analysis publishes investment, net stock, depreciation, and related statistics for types of fixed assets; it defines fixed assets as assets used repeatedly in production for a year or more. U.S. Bureau of Economic Analysis - Fixed Assets by Type The Census Bureau's former Annual Capital Expenditures Survey covered spending on new and used structures and equipment and has transitioned into the Annual Integrated Economic Survey. U.S. Census Bureau - About ACES Those sources can support an industry-level investment or asset context. They cannot tell you that Plant A has six units of Model X or plans to replace them next year.

2. Separate population, age, condition, and timing

Four variables are often collapsed into one weak claim. Population Count only assets that meet the stated inclusion rule. If public evidence says “more than ten lines,” store a range rather than selecting an invented point value. If a photograph shows equipment, verify its date and site before treating it as current. Age Age may be:

• Verified: commissioning, purchase, serial, or project date is documented.

• Estimated range: evidence supports a bounded period.

• Inferred: a building or line opened in a known year, but equipment could have changed.

• Unknown: no defensible evidence exists. Do not use building age as equipment age without confirmation. Condition and operating duty Calendar age does not reveal wear. Record utilization, load, environment, maintenance history, failure frequency, component availability, and consequence of downtime where evidence exists. The Department of Energy's operations and maintenance guide presents operational-efficiency approaches for O&M practitioners; it is a general public-sector guide, not a rule that determines when a commercial facility must replace an asset. U.S. Department of Energy - Operations and Maintenance Best Practices Timing Replacement timing requires a separate trigger, such as:

• approved capital project or public tender;

• end-of-support notice affecting the installed configuration;

• verified reliability or compliance problem;

• mandated shutdown or planned line change;

• direct statement from the facility or authorized maintainer. Age alone supports replacement exposure, not intent.

3. Map the maintenance model

The same installed base can create different ICPs depending on who maintains it. Maintenance model Typical account implication Evidence to verify In-house maintenance Site controls routine work and may source parts directly Maintenance roles, workshop, parts policy, shift coverage OEM service contract Original supplier may control diagnostics, parts, and approved changes Service agreement, warranty, authorized service terms Distributor-led Local channel stocks parts or performs first-line support Authorized directory, territory, inventory, technician capability Independent contractor Specialist may influence specification and aggregate demand Service scope, installed brands, certifications, coverage Hybrid Responsibility varies by subsystem and Responsibility matrix and escalation path risk Maintenance ownership affects more than the contact list. It changes qualification, warranty risk, documentation, stocking, minimum order, delivery urgency, field-service requirements, and whether the asset owner is the direct customer. The EIA Manufacturing Energy Consumption Survey collects establishment-level information on manufacturing energy and building characteristics at a statistical level. U.S. Energy Information Administration - About MECS It can help teams understand that asset environments and energy uses differ by subsector, but it cannot reveal a specific site's maintenance contract.

4. Apply the SellersGPT Asset-Fit Record

The Asset-Fit Record is an original SellersGPT worksheet. Maintain one record per facility and application. Field Value format Evidence rule Facility Name, address, parent Verified first-party or authoritative record Asset family Model or technical class Exact, range, or Unknown Installed quantity Integer, range, or Unknown State inclusion rule and date Age Commission year or band Do not infer from facility age alone Operating status Active, standby, inactive, Unknown Current evidence required Duty and environment Load, cycles, medium, temperature, contamination Application-specific Criticality Low, medium, high with reason Seller-defined, not official Maintenance owner Site, OEM, distributor, contractor, hybrid Named responsibility or Unknown Compatibility Compatible, conditional, incompatible, Unknown Technical gate Timing evidence Trigger and date Separate from fit Next action Research, validate, exclude, or route Owner and due date NIST research on manufacturing lifecycle data emphasizes that product and process information moves across lifecycle stages and requires context to support decisions. NIST - Contextualizing Manufacturing Data for Lifecycle Decision Making For ICP purposes, the practical lesson is to preserve what an asset claim refers to, when it was true, and how it was obtained.

5. Set evidence and decision rules

Use gates before scores. Hard gates A facility is not currently addressable when verified evidence shows that:

• the installed technology is incompatible and cannot be adapted;

• the seller cannot meet mandatory safety, quality, integration, or service conditions;

• the route requires an authorization or channel status the seller lacks;

• the asset is already decommissioned;

• outreach is suppressed or legally restricted. Evidence gates Hold the account when a critical field is Unknown. Examples include the maintained model family, maintenance owner, or hazardous-area condition. A hold is not a rejection; it is a research instruction. Optional prioritization After hard gates pass, a team may compare verified variables such as asset count, compatibility, criticality, serviceability, or evidence freshness. The score must not claim timing. Keep the underlying evidence visible. Useful calculations For a researched sample: verified installed units = sum of verified facility unit counts bounded installed units = sum of minimums to sum of maximums for verified ranges age-exposed units = verified units inside the defined age band Do not multiply age-exposed units by a generic replacement rate unless the rate has a documented, applicable denominator and conditional basis.

6. Illustrative example

Illustrative example. The supplier, facilities, installed assets, and decisions below are fictional. They do not represent a SellersGPT customer, a market forecast, or expected sales. A pump-component supplier researches four process plants. It defines an installed unit as one operating pump in the target hydraulic and material class; standby pumps are recorded separately. Site Relevant operating units Age band Maintenance model Critical unknown Alder Plant 12 9-13 years In-house None Birch Plant 6-9 5-11 years Hybrid OEM approval for seals Cedar Plant Unknown Unknown Contractor Asset family Delta Plant 8 14-17 years OEM contract Contract expiry The minimum verified-or-bounded operating population is 12 + 6 + 8 = 26; the maximum is 12 + 9 + 8 =

29. Cedar is excluded from the calculation because quantity is Unknown, not zero. If the team's age-exposure definition is at least 12 years, only evidence-supported units count. Alder's 12 units span 9-13 years, so the exact exposed subset is Unknown. Birch is below or crosses no verified threshold. Delta's 8 units are exposed. The defensible statement is therefore “at least 8 of 26-29 bounded units are in the defined age-exposure band, while Alder's split remains Unknown.” Delta does not automatically become the first outreach target: its OEM contract may block the route. The team first validates contract scope and expiry. Alder enters compatibility research. Birch enters approval-path research. Cedar remains an asset-identification task.

7. Common mistakes

Turning asset age into intent Old equipment may be reliable, fully depreciated, lightly used, or deliberately retained. Require a separate timing signal. Counting inconsistent units Do not compare machines at one site with production lines at another. Define the unit and status. Ignoring maintenance ownership The asset owner may not select parts, approve retrofits, or perform service. Map the commercial relationship. Treating Unknown as zero Unknown quantity or age should stay outside totals or appear as a disclosed range. Using aggregate investment as account evidence Industry capital spending provides context. It does not identify the installed base or budget of a named facility. Assuming obsolete means replaceable by your offer Replacement may require validation, redesign, controls integration, or certification. Compatibility remains a gate.

8. What this does not mean

• Installed-base fit is not purchase intent, budget, or an opportunity stage.

• Equipment age is not a universal replacement rule.

• A maintenance contractor is not automatically the buyer or decision maker.

• Public photographs are not reliable without site and date verification.

• This guide does not prescribe engineering, maintenance, warranty, or safety decisions.

9. Common questions

What if I only know the installed brand? Use the brand as a compatibility hypothesis. Verify model, configuration, operating duty, service status, and modification rights before claiming fit. Should standby assets count? Record them separately. They can affect parts and reliability needs, but they are not the same denominator as operating units. How fresh must installed-base evidence be? Set freshness by the asset's change rate and the decision risk. A stable heavy asset may tolerate older evidence than rapidly changing automation. Always show the date. Can I prioritize by age when condition is unavailable? You may use age as a transparent research priority, not as proof of need. Label the condition and timing fields Unknown.
