Slack time for each of the activities is: Activity: Slack time: A ______ B ______ C ______ D ______ E ______ F ______ G ______Farihah is a project manager for a systems development project involving a new database application for her organization’s human resources department. Despite Farihah’s best efforts at estimating the time requirements for the project, the team has missed the deadline for completing the Analysis Phase and producing the System Proposal. Farihah had estimated during her 6-week Planning Phase that Analysis would require 2 months, but the team finished the System Proposal 2 weeks behind their planned target date. Based on her discussions with the team members, Farihah believes that the system is more complex than she originally thought. Should Farihah adjust her timeline, or can she try to make up for the lost two weeks? Farihah needs your advice.
