IRLH Project Development of Gantt Chart

• Step 1 - Create Top-Level Strands
• Do NOT insert durations - these will
  automatically be created

Sheets - WP 1.2.1.1
Do NOT enter Start and End Dates at this stage
Enter name of WP Manager
Define Inputs required - these may be Outputs
from other WPs
Define the tasks that comprise this Work Package

IRLH Project Development of Gantt Chart

• Step 4 - Create Work Package Tasks
• Now insert task durations and interdependencies

Note Work Package Tasks can be copied from the
Work Package Description Summary Sheets Durations
are the TOTAL length of time it will take to do
the task and can be fixed or variable. Example
Preparing a meal. Time taken to cook in the oven
is fixed, whereas the time taken to prepare the
meat and veg, set the table, etc is dependent of
the number of people available

IRLH Project Compiling Costs

• Costs are compiled bottom-up using the Work
  Package as the smallest entity
• 3 Cost elements are defined (Manpower, Article 7
  and Purchases) BUT there can be any number and
  any definition
• Spreadsheet automatically rolls-up costs
  through WBS
• The number of Man-days is the time the man will
  spend on the task
