Managed software development services
This is the best option if the client software development needs require very different roles/skills to participate in the delivery or the work or when the client does not have enough work for each of the team members to work full time (FTE).
A typical example of a managed services morel is when a client needs to work on their web application, to fix bugs, develop new features and integrate third-party applications.
The client and the MSP are bound by a contractual, service-level agreement that states the performance and quality metrics of their relationship
The vendor is responsible of delivering results and its up to the vendor which people they will use to deliver them.
