Define earliest start, earliest finish, latest finish , and lateststart times.
what equation did you use? to get the earliest start time and latest start time and slack
Calculate the ES, EF, LS, and LF times and the slack for each activity in the figure below, and identify
the critical path for the project. Can the project be completed in 30 weeks? Assume that "Systems
Analysis" actually finished at 8 weeks, "Design Input & Output" actually finished at 15 weeks, and
"Design Database" actually finished at 19 weeks. Recalculate the expected project completion time.
Which activities would you focus on to get the project back on schedule?

- Question 1 The longest time period you can go without updating a schedule is no more than 3 weeks. True False Question 2 0 Network Loop is the process by which relationships between activities are created. Activities are linked finish-to-start start-to-start, finish -to -finish, or start-to-finish and can include lag or lead times. True False Question 3 A constraint is a restriction imposed on the start date, finish date or other aspect of an activity. Constraints are used to prescribe limitations on the schedule based on external conditions such as contractual restrictions or imposed float requirements.

Remi's wage for his casual job is $600, paid on his bank transaction account (transaction 1); his scholarship allowance for studying is $150, paid on his bank transaction account (transaction 2); he pays a rent of $250 through a bank account transfer (transaction 3); the coupons on his portfolio of bonds pays $70 on his transaction account (transaction 4); he receives $350 in his transaction account for selling shares he had bought at $300 (transaction 5); he buys a TV worth $920 with his debit card (transaction 6). Draw Remi's balance sheet and represent how the six transactions above have affected it. Use one single balance sheet, indicate the value of the variations (sign followed by a number) and use only one name for each item [example: equity name appears only once even if several transactions are under equity] No explanations are required.
