One Version of the Truth: Why Installation Businesses Need a Single Source of Job Information
A customer changes their installation date. The scheduler updates the diary. Someone updates the project spreadsheet. The installer is told by phone. An email containing the new arrangements is sent to the customer.
But the survey team is still working from the original information.
Nobody has necessarily done anything wrong. The problem is that several different versions of the same job now exist.
For small installation businesses, this may be manageable. People sit close to one another, there are relatively few live jobs, and missing information can often be resolved by asking the person who knows.
As the number of customers, installations and employees increases, that approach becomes increasingly difficult.
What does “one version of the truth” mean?
A single version of the truth means having an agreed, authoritative source for important operational information.
For an installation business, that might include:
- customer and property information
- current job status
- surveys and survey results
- appointments
- assigned installers and subcontractors
- measures or products being installed
- documents
- photographs and site evidence
- outstanding actions
- compliance information
- remedial work
- completion status
It does not necessarily mean that every business function has to use one piece of software. It does mean that everybody should know where the definitive information about a job resides.
How multiple versions develop
The problem usually develops gradually.
A business might begin with a spreadsheet for enquiries and another for installations. A shared calendar is introduced for appointments. Documents are stored in folders. Photographs arrive by email or messaging apps. Another system handles quotations or invoicing.
Each addition solves an immediate problem.
Eventually, however, the business can have information about the same installation spread across several different locations.
The difficulty is not simply finding information. It is knowing which information is correct.
This is closely connected to duplicate data entry, because every additional system creates another opportunity for the same information to diverge.
Why conflicting information is dangerous
Consider something as simple as an installation date.
If the CRM says Monday, the spreadsheet says Tuesday and the installer's calendar says Wednesday, somebody has to determine which is correct.
Getting it wrong could mean a missed installation appointment, a wasted journey and reputational damage.
Similar discrepancies can affect addresses, telephone numbers, survey information, installation specifications, assigned teams and job status.
The administrative cost of resolving these differences can be significant. More importantly, decisions could be made using outdated information, resulting in loss of revenue and reputation.
The hidden dependency on individuals
Disconnected information also creates reliance on particular employees.
Someone inevitably becomes the person who “knows what is going on”. That can work surprisingly well until that person is unavailable, changes role or leaves the company.
A well-structured operational system should allow an authorised colleague to understand the current position of a job without having to find the person who last dealt with it.
Creating a reliable operational record
Moving towards a single source of truth normally requires more than simply purchasing software.
Businesses need to decide:
- what information should be recorded
- where it should be recorded
- who is responsible for updating it
- which events change a job's status
- which information field teams need
- which information management needs
- how documents and evidence relate to the underlying job
The objective is not to collect as much information as possible. It is to make the important information reliable.
Reliable data also improves management reporting, because reporting is only as good as the information underneath it.
The benefits become greater as the business grows
When a company has five employees, informal communication can compensate for imperfect systems.
With multiple surveyors, installation teams, administrators, project managers and subcontractors, that becomes considerably harder.
A reliable central job record can reduce time spent checking information and give different parts of the organisation a common view of what is happening.
This becomes especially important when scaling an installation business and adding more teams, disciplines or locations.
How Instalr can help
Instalr is designed to provide installation businesses with a central operational record for customers, projects and jobs, bringing together information such as job progress, appointments, documents and installation activity in one place.
For growing installation businesses, having operational information organised around the job can help reduce reliance on disconnected spreadsheets, files and individual knowledge, while giving authorised office and field teams a clearer shared view of current work.
