Every facility team eventually asks the same question about each service line: keep the work in-house, or hand it to a contractor? Most organisations answer it one service at a time, in different meetings, using different assumptions, and end up with a patchwork nobody can defend when budgets tighten. This checklist turns the make-versus-buy question into a repeatable score across four lenses: cost, capability, risk, and strategic value. Run it in a single workshop and back every score with real work history from Oxmaint maintenance management software.
Facility Sourcing Decision Tool
Facility Self-Perform vs Outsource Decision Checklist
Score every facility management service on cost, capability, risk, and strategic value, then place it on the sourcing spectrum with evidence instead of habit.
Self-performScore 15 to 20. Core to operations, skills in place, control matters.
HybridScore 10 to 14. Keep daily work in-house, contract the specialist tasks.
OutsourceScore 4 to 9. Commodity, specialist, or highly variable demand.
Why Sourcing Decisions Drift Without a Scoring Method
Sourcing choices are usually made after a pain event: a contractor misses a response time, a senior technician retires, or finance asks for a cut. The decision that follows is reactive, and nobody records why it was made.
Decision by habit
- Triggered by a failure, a resignation, or a budget cut
- Each service judged on a different basis
- In-house cost shown as hourly pay only
- Reasoning never written down
- Not revisited until the contract expires
Decision by checklist
- Every service scored on the same four lenses
- Labour, tools, overhead, and contract management priced on one sheet
- Work-order history supplies the real workload
- Red flags and overrides recorded with the score
- Review date set on the day of the decision
The Four Lenses and What a Score Means
Each lens is scored from 1 to 5 by how strongly it favours keeping the work in-house. A 5 means self-perform is clearly better on that lens. A 1 means a contractor is clearly better.
1
Cost
1: Contract is cheaper at your real volume.
5: In-house is cheaper once all costs are included.
2
Capability
1: Skills, licences, or tools are missing.
5: Team is trained, certified, and covered across shifts.
3
Risk
1: Specialist liability transfer reduces exposure.
5: Direct control lowers safety and continuity risk.
4
Strategic value
1: Commodity service with no differentiation.
5: Directly shapes occupant experience or asset knowledge.
The Per-Service Workshop Checklist
Work through one service at a time. Answer each question with data where possible, then enter a 1 to 5 score for the lens at the end of each group.
Lens 1: Cost
Fully loaded labour rate. Include wages, benefits, training, overtime, supervision, and vehicle costs, not just the hourly pay figure.
Annual workload hours. Pull twelve months of work orders to see actual hours per service rather than estimates from memory.
Utilisation of staff. Check whether technicians stay productive on this service or sit idle between seasonal peaks.
Tools, software, and calibration. Price specialist equipment, licences, and test instruments that the service needs.
Contract price benchmark. Collect at least three quotes against an identical scope sheet so prices compare like for like.
Hidden and transition costs. Add contract administration time, mobilisation, change orders, and the cost of bringing work back later.
Lens 2: Capability
Skills inventory. List the competencies the service requires and match them to named people on your team.
Statutory licences and certifications. Confirm which tasks legally require a licensed party in your jurisdiction, such as lift, fire alarm, or refrigerant work.
Coverage depth. Test whether leave, sickness, and out-of-hours calls can be covered without relying on one person.
Technical supervision. Confirm a qualified lead can review work, sign off, and escalate faults beyond the team's skill.
Parts and tooling access. Check supplier accounts, stock levels, and lead times for the parts this service consumes.
Recruitment and training pipeline. Assess how hard it is to hire and retain these skills in your market.
Lens 3: Risk
Life-safety and regulatory exposure. Identify whether a missed task creates a code violation, injury risk, or audit finding.
Liability and insurance. Compare your insurance position with a contractor's cover and the indemnities a contract would give you.
Response-time criticality. Decide whether failures need minutes or days, and whether a contractor can credibly meet that window.
Continuity of supply. Look for single points of failure on either side, including one technician or one vendor.
Vendor market depth. Count qualified local providers, because a thin market weakens your negotiating position.
Access and data security. Review who needs entry to tenant areas, plant rooms, and building control systems.
Lens 4: Strategic Value
Link to core mission. Ask whether the service directly shapes occupant experience, production uptime, or patient and tenant outcomes.
Knowledge retention. Consider how much asset history and site knowledge walks out the door if a contractor changes.
Demand variability. Flex capacity is easier to buy than to employ when workload swings widely.
Access to technology. Check whether a specialist provider brings diagnostic tools or methods you cannot justify owning.
Control over standards. Weigh how much you value setting service culture, behaviours, and presentation directly.
Portfolio consistency. Consider whether bundling across sites gives leverage or whether local teams serve each site better.
Turning Scores Into a Sourcing Decision
Add the four lens scores for a total between 4 and 20. Use the band as a starting position, then apply the override rules before you commit.
| Total score | Starting position | What to do next |
|---|---|---|
| 15 to 20 | Self-perform | Protect the capability with training, spares, and documented procedures. |
| 10 to 14 | Hybrid | Split the service: routine tasks in-house, specialist or peak work contracted. |
| 4 to 9 | Outsource | Write a performance-based scope with clear service levels and exit terms. |
Override rules
- If a statutory licence is required and you do not hold it, outsource that task regardless of score.
- If a single lens scores 1 on a life-safety service, escalate to a risk review before deciding.
- If no qualified vendor exists locally, treat outsourcing as high risk and build in-house capability.
- If the scores sit within one point of a band edge, run a time-limited pilot instead of a full switch.
Starting Hypotheses by Service Line
These are common starting points, not answers. Your own scores, market, and contracts decide the outcome.
| Service | Common starting lean | Deciding question |
|---|---|---|
| Routine HVAC preventive maintenance | Self-perform or hybrid | Can you cover filters, belts, and inspections with consistent skills? |
| Chiller and boiler overhaul | Outsource | Do you need OEM tools or licensed refrigerant handling? |
| Elevator maintenance | Outsource | Does local law restrict who may service lifts? |
| Fire alarm and sprinkler testing | Hybrid or outsource | Are certified testers available in-house? |
| Janitorial | Outsource or hybrid | Does demand vary by occupancy and shift? |
| Grounds and snow removal | Outsource | Is equipment idle for most of the year? |
| Electrical minor works | Self-perform | Do licensed electricians cover normal workloads? |
| Building automation controls | Hybrid | Who holds programming access and documentation? |
Building a True Cost Comparison
Most sourcing errors come from comparing a contract price with only part of the in-house cost, or the reverse. List both stacks in full.
In-house cost stack
- Wages, benefits, and payroll taxes
- Training and licence renewals
- Vehicles, tools, and test instruments
- Supervision and administration time
- Parts holding and storage
- Cover for absence and out-of-hours work
Contract cost stack
- Contract fee and annual indexation
- Out-of-scope and call-out charges
- Parts markup and consumables
- Contract management and audit time
- Mobilisation and handover
- Exit and re-tendering cost
Sourcing Mistakes the Checklist Prevents
Most poor sourcing outcomes trace back to a handful of repeatable errors. Use this table as a sanity check before approving any change.
| Mistake | What goes wrong | Checklist control |
|---|---|---|
| Comparing price with wages only | In-house looks cheaper than it is, or contracts look dearer than they are | Complete both cost stacks |
| Outsourcing after one bad incident | A people or process problem moves to a new vendor unchanged | Score all four lenses, not just risk |
| Losing asset knowledge | New vendors repeat past failures because history sits with the old team | Strategic value lens, plus records in the CMMS |
| Vague contract scope | Disputes over what is included and constant change orders | Scope sheet used for benchmark quotes |
| No exit plan | Dependence on one provider and weak bargaining power | Governance checklist and review date |
Piloting a Borderline Service
When a service lands near a band edge, a time-limited pilot is safer than a permanent switch. Keep the pilot small and measurable.
- Choose one site, building, or asset group so the comparison stays clean.
- Write the success measures before the pilot starts, using the KPIs in this checklist.
- Run the pilot long enough to include a seasonal peak, usually at least one full quarter.
- Keep the old model available as a fallback until the pilot results are reviewed.
- Record every work order the same way under both models so results compare fairly.
Signs the current model is failing
- Preventive maintenance completion keeps slipping despite reminders.
- The same assets return with repeat faults after each visit.
- Invoices rise faster than workload, and out-of-scope charges grow.
- Key knowledge sits with one person or one account manager.
- Audit findings recur on the same regulated tasks.
Keep Sourcing Evidence in One Place
Oxmaint records labour hours, parts, and response times for in-house and contractor work, so your next sourcing review starts with facts.
Running the Decision in One Workshop
A single half-day session works when the data is gathered beforehand. Invite operations, finance, safety, and procurement so no lens is scored by one department alone.
Before the workshopPull the evidence. Export twelve months of work orders, labour hours, call-outs, and contractor invoices for each service.
Hour 1Agree the service list and scope. Define each service so everyone scores the same boundary of work.
Hours 2 and 3Score each service. Work through the four lens groups and capture a score with a one-line rationale.
Hour 4Apply overrides and rank. Test the borderline services and list the pilots or tenders needed.
After the workshopRecord and schedule review. Store the scorecard with the asset records and set a review date within twelve months.
After the Decision: Governance Checklists
Choosing the model is the easy part. The decision only holds if you run the chosen model with discipline.
If you self-perform
- Keep a skills matrix and training plan per technician
- Write standard job plans for recurring tasks
- Track parts and critical spares
- Audit completed work through supervisor sign-off
- Rebenchmark costs against the market yearly
If you outsource
- Define service levels and response times in the contract
- Require work orders and completion evidence for every visit
- Agree who owns asset data and records
- Audit a sample of completed jobs each quarter
- Negotiate exit and transition terms upfront
How Oxmaint Supports the Sourcing Decision
Sourcing reviews fail when nobody trusts the numbers. A maintenance system gives you a single record whichever model you pick.
| Oxmaint capability | How it helps the decision |
|---|---|
| Work orders and labour tracking | Shows real hours and cost per service before you score cost. |
| Asset management | Links repair history to each asset, which exposes skill gaps and repeat failures. |
| Preventive maintenance scheduling | Keeps recurring tasks on time under either model. |
| Inspections and compliance records | Provides evidence for risk scores and audit trails for regulated tasks. |
| Mobile workflows | Lets in-house technicians and contractor staff close jobs with notes and photos on site. |
| Inventory and reporting dashboards | Tracks parts use and compares performance across vendors and teams. |
Documenting the Decision for Auditors and Successors
A sourcing decision that cannot be explained in two years will be reopened from scratch. Store a short decision record for every service.
Decision record contents
Scope statement. The exact tasks, assets, and locations the decision covers.
Scores and rationale. Four lens scores, the total, and the one-line reason behind each.
Overrides applied. Any legal, safety, or market rule that changed the starting position.
Approvers and date. Names of those who signed off, plus the planned review date.
Success measures. The KPIs that will prove or disprove the choice.
KPIs to Track After the Decision
Measure the same indicators under both models. If a sourcing choice is working, the numbers show it within a few quarters.
| KPI | What it shows | Review |
|---|---|---|
| Preventive maintenance completion | Whether planned work is actually done on time | Monthly |
| Response time against target | Service level performance, including contractor SLAs | Monthly |
| First-time fix rate | Skill and parts readiness | Quarterly |
| Repeat call-out rate | Quality of repair and diagnosis | Quarterly |
| Actual cost against scorecard forecast | Accuracy of the original cost lens | Quarterly |
| Compliance task completion | Audit readiness for regulated services | Monthly |
Frequently Asked Questions
How often should we revisit a sourcing decision?
Review at least annually and before any contract renewal. Compare actual KPIs with the scorecard forecast.
Can one service be split between in-house and contractor?
Yes. A hybrid model often fits best. Keep routine work in-house and see how work orders can track both.
What data do we need before the workshop?
Twelve months of work orders, labour hours, invoices, and compliance records. Oxmaint can centralise this data.
Should cost outweigh the other lenses?
Not automatically. Cost is one of four lenses, and risk or legal requirements can override a cheaper option.
Does this checklist work for a single building?
Yes. Smaller sites often have thinner vendor markets and less coverage depth, so score those lenses carefully.
