Use the following brief to assist you in answering the question about the wildfire project:
The City of Kelowna has come to you with the following problem that needs to be solved with a maximum budget of $250,000.00. The project description provided is as follows: “The city of Kelowna would like a device that predicts the likelihood of wildfires in various locations around the Okanagan in real-time so that preventative measures can be implemented strategically to decrease the likelihood of a wildfire starting in these riskiest areas. Currently, no locational prediction is being done in the Okanagan region and region-wide fire predictions have low accuracy. The city has specified that the solution must be able to predict fire hazards at more than 20 unique locations in the Okanagan region and must be ready by June 2023, the start of the next fire season.”
Your team starts by developing a need statement. Based on the client description above (no scoping) which needs statement best frames this problem?
A. A way to address the lack of locational prediction of fire risks for the Okanagan.
A way to address the lack of locational prediction of fire risks for the Okanagan.
B. A way to build an app that predicts fire risk by taking temperature measurements in the Okanagan.
C. A way to address the lack of locational prediction of fire risks for British Columbia.
D. A way to build a temperature probe that predicts fire risk in Kelowna.
A. A way to address the lack of locational prediction of fire risks for the Okanagan.
The need statement for a project to predict the likelihood of wildfires in various locations around the Okanagan in real-time is: “A way to address the lack of locational prediction of fire risks for the Okanagan.”
