Key Insights

1. The development team is scheduled for active work during weeks 7 through 14 (8 out of 14 weeks), making up approximately 55-60% of the project's total timeline.
2. The schedule is highly structured, with tasks generally following a sequence: marketing research, planning, then development and testing, with some team overlaps.
3. Several weeks (notably around weeks 7-9) feature multiple tasks starting, highlighting critical coordination periods and points of high cross-team activity.
4. Each team's work is clustered, allowing for phased responsibility and clear hand-offs between marketing, planning, and development.

Step-by-Step Solution

Question 1: Calculating the Percentage of Weeks the Development Team is Active

Complete Statement:

To the nearest 5 percent, the number of weeks the development team has at least one task scheduled is [BLANK] percent of the total duration represented by the chart.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: the development team has at least one task scheduled
  • Meaning: We need to count every week where the development team is working on any scheduled task.
  • Relation to Chart: This corresponds to all the black bars on the chart, as they represent the development team's tasks.
  • Important Implications: If the team is working during several tasks in the same week, it should still count as one week.

• Statement Breakdown 2:
  • Key Phrase: percent of the total duration represented by the chart
  • Meaning: Calculate the ratio of team-active weeks to total weeks in the chart, then convert to a percent.
  • Relation to Chart: The chart shows the project's duration is 14 weeks.
  • Important Implications: The calculation must be \((\text{number of development weeks}) / 14 \times 100\%\).

• What is needed: Count the weeks when the development team is scheduled, find their fraction of 14, and round the result to the nearest 5 percent.

Solution:

• Condensed Solution Implementation:
  Review all task bars belonging to the development team and list the weeks they cover.
• Necessary Data points:
  Development team works on: Detail Design (weeks 7-8), Development (weeks 9-12), Test Plan Segment 2 (weeks 11-12), Testing and QA (weeks 12-14), User Documentation Segment 2 (weeks 13-14).
• Calculations Estimations:
  Total weeks with development tasks: 7, 8, 9, 10, 11, 12, 13, 14 = 8 weeks. Percent = \((8 / 14) \times 100 \approx 57\%\). Rounded to the nearest 5 percent: 55%.
• Comparison to Answer Choices:
  The calculated 57% is closest to 55% (as \(57\% - 55\% = 2\%\), but \(60\% - 57\% = 3\%\)).

FINAL ANSWER Blank 1: 55

Question 2: Identifying the Week When Three Tasks Begin

Complete Statement:

Week [BLANK] is the only week during which three different tasks are scheduled to begin.

Breaking Down the Statement

• Statement Breakdown 1:
  • Key Phrase: three different tasks are scheduled to begin
  • Meaning: We need to find a week where three separate tasks all start.
  • Relation to Chart: This means three bars have their left endpoint aligned with the given week number.

• Statement Breakdown 2:
  • Key Phrase: the only week
  • Meaning: There is exactly one week with this property among the answer choices.
  • Relation to Chart: Review each candidate week for the number of task starts.

• What is needed: Determine which week between 6 and 10 is the only one where three tasks start.

Solution:

• Condensed Solution Implementation:
  Check how many tasks start in each week among the answer choices.
• Necessary Data points:
  Week 6: 1 task start; Week 7: 1 task start; Week 8: 3 tasks start (Market Research segment 2, Test Plan segment 1, Testing and QA); Week 9: 1 task start; Week 10: 1 task start.
• Calculations Estimations:
  Only Week 8 has three new task bars starting.
• Comparison to Answer Choices:
  Week 8 is among the choices and matches the condition: three tasks begin.

FINAL ANSWER Blank 2: 8

Summary

By reviewing the chart, the development team works 8 out of 14 weeks, yielding 57%, which rounds to 55%. For task starts, only Week 8 has exactly three tasks starting among the options. Careful reading and systematic counting give the answers quickly and accurately.

Question Independence Analysis

The first blank asks about development team participation throughout the schedule, while the second asks for a specific week with three task starts. These are independent: calculating one does not affect the other.
