Question
Chapter 7, Problem 4AME
Summary Introduction
Interpretation:The effect of increasing activity A by 1 week after becoming critical is to be determined.
Concept Introduction: Critical path is a method used to evaluate the project. It is used when the activity times are deterministic. It is the longest path in the network. It defines the minimum time required for completion of the project.

Find the minimum possible completion time of the project by considering the crashed
completion times and the minimal total cost of that crashing the project.
Highlight the critical and non-critical activities of the finally completed project by taking into
account the crashed times of activities.
Roger Ginde is developing a program in supply chain management certification for managers. Ginde has listed a number of activities that must be completed before a training program of this nature

- PROJECT A Project A is a planning, design and implementation infrastructure development project (about GHS 15 million in value and expected to take about three years from the start of planning to completion), which is well advanced in its planning component. While the project is progressing well in terms of time, cost and quality, there are a number of sustainability and stakeholder management issues with it. This project is being undertaken in an environmentally sensitive area in which leave several property owners who are quite concerned with the impact of the project on their environment. They are concerned that a thorough environmental risk assessment has not been undertaken with respect to the long-term impact on the sensitive bushland area in which they live. They are also concerned that completion of the project, through providing the basis for significant property development and destruction of bushland, will forever change the social fabric of their region.
