| All electrical components are ordered locally from a single website: Mauser Portugal. Sourcing from one supplier ensures that all parts arrive together and reduces costs to a single shipping fee.

| - | === 3.8.2 Decision Making === | + | === 3.8.3 Procurement risk and mitigation === |
| + | |||
| + | The primary risks include exceeding the budget and shipping delays. To mitigate these risks, all electrical parts are ordered from one local supplier, Mauser.pt. This ensures all parts arrive together and reduces shipping costs to a single fee. Structural cork is also sourced locally in Porto to support the regional economy and avoid long transit times. | ||
| + | |||
| + | === 3.8.4 Cost and constraints === | ||
| + | |||
| + | The project operates under a strict budget constraint of 100 €. Costs are determined by selecting affordable and reliable off the shelf components. The current estimated cost for the prototype is 51.70 €, which leaves a safety margin for unexpected expenses. | ||
| + | |||
| + | Procurement constraints are presented below: | ||
| + | |||
| + | Budget: Total spending cannot exceed 100 €. | ||
| + | |||
| + | Schedule: Procurement must align with the fixed 17.5 week project timeline and specific sprint deadlines. | ||
| + | |||
| + | Resources: All assembly and procurement tasks must be handled by the six internal team members. | ||
| + | |||
| + | === 3.8.5 Decision Making === | ||
| Decisions are based on budget and time limitations. It is not possible to manufacture every part within the given timeframe, like ESP32 boards. A readymade solenoid valve was selected instead of building a custom valve with a servo motor. This choice ensures a reliable, leak-proof solution and saves time during the development phase. Specific parts needed to have certain features to ensure longevity of the product like more expensive model of anticorrosion temperature sensor. | Decisions are based on budget and time limitations.

| + | === 3.8.6 Vendor management === | ||
| + | |||
| + | The team will manage suppliers by tracking order status online and verifying the quality of components upon delivery. Local sourcing from Mauser.pt simplifies communication and returns if parts are defective. | ||
