Final answer:
The exact percentage of schedule devoted to requirements in faster projects, according to Blackburn, Scudder, and Van Wassenhove (1996), isn't specified in the question. However, efficient requirements management is critical for reducing development time and costs, and improving project outcomes.
Step-by-step explanation:
According to the study by Blackburn, Scudder, and Van Wassenhove (1996), as mentioned in Software Requirements, 3rd edition, faster projects allocate a specific portion of their schedule to the requirements phase. Although the exact percentage is not provided in the question, studies in project management and software development typically suggest that requirements gathering is a critical phase in any project. The time devoted to this phase can significantly impact the overall success and speed of the project completion. Efficient requirements management can lead to reduced development time and costs, and improve project outcomes. It is generally recommended that adequate time be set aside for this phase to ensure project requirements are well understood and documented.
