Feasibility AnalysisFeasibility Analysis

Attribute Scale Why Solution

R1 Sufficient Skills 5 The Project is programming intensive and we have the required experience.

None

R2 Sufficient Equip 4 The team has the funds to acquire the necessary equipment, though on a small scale. Most lab equipment will be enough, and team can use laptops which are already obtained

Need to create a budget for equipment that is as of yet unattained

R3 Technology 3 For the most part the technology needed to complete this project is available. However, GPS devices have a 3m error which could be a problem.

Research techniques which could solve this problem such as using ground reference points.

R4 Sufficient People 4 There are 4 members which is enough None

S1 Sufficient Time 3 Creating a reconnaissance vehicle is an extensive project which may require a large commitment in order to fully complete.

Get started as soon as possible.

E1 Sufficient Funds 3 The team has the funds needed to acquire the necessary equipment, though on a small scale. Replacement equipment do to random errors will be costly however

Save money just in case of damaged equipment. Assume we may need 2 of every, and save money accordingly.
