Project Methodology – Which technology?
• Start from the use case and expected services and users
• Which machines must be connected on the field
• How mobile are these machines, what connectivity do they have already
• Timeframe: fast deployment, lifetime, future evolutions
• Your skill in telecom and connectivity (operate a network?)
• Programming and integration skills
• Scope of work for partners and suppliers
• Reliability of partners and suppliers and technology over time
