Outsourcing a SharePoint Project vs doing it with an in-house contract resource

Element	Outsourcing as a Project	Doing the project in-house with a resource (mid level resource to developer category)
Requirements Gathering	You will have Senior and experienced consultants doing this activity, which results in precise understanding of the requirements	The resource will be more technical and so this would not be an easy task for him to do, even if he does, it would result in a poorly compiled understanding
Project Scoping	Results from the Requirements: Sr People would be in a much better position to do this	Would not be able to do
Hardware Sizing and Capacity Planning	Sr. Consultant required	Would be out of reach for a Jr Resource
Creating High Level and Low Level Design documents	Sr. Technical Consultant required	Would not be able to be do
Development and Quality Control	Can bring in a team of people monitored by excellent team leads and testing team to always ensure every piece of development goes through a Quality Check before release	Such processes are very hard to establish
Project Team	Project Team will comprise of Project Manager, SharePoint Architect, Project Coordinator, Team Leads, Tech Leads, Developers, Test Leads and Testers	Such a team cannot be formed and one person might be expected to play multiple roles thus falling way short of expectations
Ongoing Project Management	Project Manager and Project Coordinators will always be there to support	Inhouse people have to do Project Management among various other activities they might be already involved in
Timelines	As a project, the vendor is responsible to deliver as per project timelines agreed	Controlling timelines would be very hard
Effort Estimates	Effort Estimates are more correctly done by Sr Consultants	Efforts estimates if done by a developer will never be right
Best Practices	Best Practices and Processes shall be brought in by the vendor	Very hard for a single person to be aware of best practices, processes
Cost	Cost shall be based on man days or fixed bid and will be relatively higher	Cost shall be based on monthly contracts and will be lower
Resource satisfaction levels	SharePoint resources working as part of a Software Company will be highly satisfied	Resources working alone as part of a Non-IT setup will not be satisfied and may constantly look for a jump, leaving the project in jeopardy
Technical Advice, Guidance	Such advice and guidance will constantly come from Sr. Members	No such advice may be available and infact, Sr members as part of the internal IT setup may possibly give wrong directions
