Critical Path Method (CPM): Activity, Duration, Predecessor

Steps: -1.) draw activity on Node (AON) Diagram -2.) calculate Forward Pass (includes Earliest Start(ES) and Earliest Finish(EF)); move from left to right, adding task times; EF = ES + activity's duration -3.) determine Project Duration, set Latest Finish(LF) times for all ending nodes -4.) calculate Backward Pass (includes Latest Start(LS) and Latest Finish(LF)); move from right to left, subtracting task times; LS = LF - activity's duration -5.) determine Critical and Slack activities; Slack Time = LS - ES -6.) evaluate Crashing (shortening the overall duration of a project by reducing the time it takes to perform some of the activities (by adding more equipment/people, using overtime, etc.)), if needed

Operations and SC Strategy Objectives

Types of Management Tools for Project Control

-1.) Gantt Charts = graphical tools used to show expected start and end times for project activities and to track actual progress against these time targets -2.) Critical Path Method (CPM) = a network-based technique in which there is a single time estimate for each activity

Three Basic Reasons to Study Supply Chain

-1.) Pervasiveness = every organization must make a product or provide a service that someone values (manufacturer, retailer, design firm, university, health services) -2.) Interdependence = most organizations function as part of a larger supply chain -3.) Profitability & Survival = organizations must carefully MANAGE their operations and supply chains in order to prosper, and indeed, survive

Process Map Basic Steps

-1.) identify the entity that will serve as your focal point (e.g. customer?; order?; item?) -2.) identify clear boundaries, starting and ending points -3.) keep it simple (e.g. does this detail add any insight?; do we need to map every exception condition?)
