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.
