Final answer:
Projects in a traditional functional organization can be slow and uneconomical due to hierarchical decision-making and departmental silos that lead to inefficiencies.
Step-by-step explanation:
False. Projects executed using the traditional functional organization are not necessarily fast; in fact, they often suffer from slow decision-making due to the hierarchical structure. Moreover, this organizational structure does not guarantee economical outcomes due to potential inefficiencies such as departmental silos and poor communication across different functions, which can lead to delays and cost overruns. These issues could hinder the ability to adapt quickly to changing project requirements and to deliver economically efficient results.
