Developing an aviation system or application that is compliant with challenging standards like ARP 4754A or DO-178C can be a daunting task.  

For those taking on a compliant project for the first time, the complexity of the standard(s) and the overheads implied by that complexity can seem breathtakingly onerous. More experienced practitioners can be haunted by challenges faced in past projects, and question how they can learn from them to make future projects more cost and time effective.  

Small wonder that many development teams seek the reassurance that expert consultants can bring.
