Delivery Models

A time and materials contract is a type of agreement where a client pays a contractor based on the actual time spent working on a project and the cost of materials used. Unlike fixed-price contracts, T&M contracts don't set a final price beforehand; instead, they outline hourly rates for labor and the cost of materials, allowing for flexibility as the project evolves. This model is often preferred when the project scope is uncertain or likely to change. 

The Scope Projects model, within the context of contracting methods, refers to a project delivery approach where the project's scope of work is clearly defined and agreed upon before the contract is finalized. This model emphasizes a detailed specification of the project's requirements, deliverables, and boundaries, ensuring all parties have a common understanding and minimizing potential disputes related to the project's extent. 


In a Managed Services Model, a third-party provider, known as a Managed Services Provider, takes on the ongoing, day to day management of a client’s infrastructure, systems, or processes. Unlike traditional support models where a provider only addresses issues as they arise, the MSP takes a proactive approach, continuously monitoring, maintaining, and optimizing operations to prevent problems before they occur. Services are typically delivered under a Service Level Agreement, ensuring performance standards, accountability, and predictable costs.
