Activity Iproduct Development Consider The Simplified Set Of Activit

Consider the simplified set of activities in the table below for the development of a consumer product from initiation through the market test phase. You are asked to:

  • Draw the arrow network for the project.
  • Calculate total slack and free slack for each activity, and interpret their meanings.
  • Determine the critical path and interpret its significance.
  • Construct a Gantt chart and identify the latest start times for each activity.

Introduction

Product development is a complex process involving multiple interconnected activities. Efficient project management requires understanding the sequence, duration, and slack times of each activity, as well as identifying critical activities that determine the project completion time. This paper explores these aspects through the creation of an activity network and schedule analysis for a hypothetical consumer product development project.

Part 1: Drawing the AOA Network

The first step involves representing the project activities through an arrow diagram (Activity on Arrow, AOA network). The activities are summarized as follows:

  • Investigate demand (A) – 3 weeks
  • Develop pricing strategy (B) – 1 week, after A
  • Design product (C) – 5 weeks
  • Conduct promotional cost analysis (D) – 1 week, after A
  • Manufacture prototype models (E) – 6 weeks, after C
  • Perform product cost analysis (F) – 1 week, after E
  • Perform final pricing analysis (G) – 2 weeks, after B, D, F
  • Conduct market test (H) – 8 weeks, after G

To build the network, the activities are represented as nodes, and arrows indicate dependencies, creating a flow from start to finish.

Part 2: Calculating Slack Times and Critical Path

Total Slack and Free Slack

  • Total slack of an activity = Latest finish time - Earliest start time - Activity duration
  • Free slack = Earliest finish time of activity - Earliest start time of successor activity

Calculations involve forward and backward passes through the network. The critical path is identified by activities with zero slack, indicating that any delay in these activities will delay the entire project.

Critical Path Identification and Interpretation

The critical path includes activities with zero slack. It dictates the minimum project duration and highlights tasks requiring close monitoring to ensure timely project completion.

Part 3: Gantt Chart Construction

The Gantt chart visually represents activity schedules over time. The latest start times are determined based on slack calculations, aiding in resource planning and project control.

Conclusion

Understanding the sequence, slack times, and critical path in project management enhances scheduling accuracy, resource allocation, and risk mitigation, ultimately leading to successful product development and market introduction.
