Barr Group vs RMB Consulting: overview

Barr Group

Barr Group was founded in 2012 and is headquartered in Gaithersburg, Maryland, with a team in the 51 to 200 employee range. Led by CTO Michael Barr, a former editor-in-chief of Embedded Systems Design magazine and author of multiple embedded software books, the firm's identity centers on independent training, firmware process and architecture consulting, and legal and corporate technical expert-witness work rather than volume development. That positioning, expertise as the product rather than headcount as the product, is what a consulting-first buyer is specifically looking for when the engagement is advisory rather than build-and-ship.

RMB Consulting

RMB Consulting has operated in embedded systems design and consulting since 1995, run by founder and chief engineer Nigel Jones, who brings more than 30 years of professional embedded systems engineering experience. The firm covers hardware, software, and firmware consulting with a team of 1 to 10 people, positioning it at the smallest and most direct end of the advisory spectrum on this list. Nigel Jones is also a recognized voice in the embedded engineering community through long-running technical blogging on firmware design topics, which gives a prospective client a substantial public track record to evaluate before ever making contact.

Barr Group vs RMB Consulting: pros and cons

Barr Group
+ Led by Michael Barr, a widely recognized embedded software authority and published author, giving the firm's advisory opinion real external credibility
+ Training and expert-witness services are core, established business lines, not a marketing add-on to a dev-shop offering
+ 13 years of operating history built specifically around advisory and process-improvement work
+ 51 to 200 employees give enough bench depth for concurrent training and consulting engagements without positioning as a large build shop
- Volume development capacity is not the firm's stated focus, so a buyer needing a large parallel build program may need a second vendor
- No published consulting rate or minimum engagement figure
- Legal expert-witness work is a distinct service line from product consulting; confirm which practice area an inquiry is routed to
RMB Consulting
+ 30 years of professional embedded systems experience concentrated in a single named principal, not diluted across a large team
+ 30 years of operating history under the same founder gives long continuity of technical judgment
+ A substantial public record of technical writing on firmware design topics lets a prospective client evaluate expertise before engaging
+ Very small team size means no account-management layer between the client and the engineer doing the work
- A team of 1 to 10 people severely limits capacity for a large or multi-workstream engagement
- No published pricing or minimum engagement figure
- Availability may be constrained given the founder-led, low-headcount structure
