Compare another operationInsurance operations research — draft
Custom computer programming firms write, modify, test, and support software tailored to specific client requirements — ranging from small business applications to enterprise integrations, mobile apps, APIs, and embedded systems. Work is typically delivered under a statement of work or contract, often involving iterative development cycles. Most client interaction is remote or at client sites; physical premises are generally low-hazard office environments.
Questions to investigate
- What industries do the firm's clients primarily operate in — healthcare, financial services, general commercial, consumer apps, or other?
- Does any of the software touch life-safety systems, medical devices, critical infrastructure, or payment card processing?
- Does the firm use independent contractors or subcontractors for development work, and are they under written agreements?
- What is the firm's largest single client as a percentage of total revenue?
