A mining-services company creates a sourcing team to select a supplier for condition-monitoring technology used on critical equipment. The team includes supply management, maintenance, information systems, finance, and site operations. After three meetings, the team has gathered useful technical, operational, and cost information, but progress is uneven. Maintenance wants more field testing, information systems is concerned about data integration, finance wants a clearer cost model, and supply management is worried that the decision date will be missed. The steering manager wants the team to remain responsible for the recommendation, but also wants stronger discipline in how the team moves from analysis to decision. Based on the scenario, which approach best aligns with the steering manager's requirement?
