What’s the problem?


You are a property developer…

You are renovating a houseThere are various tasks that this involvesWhich will each take a different time to complete


Some tasks have to be finished before others can begin

You want to complete the renovation as quickly as possible


Is it possible to complete the project before your deadline?

In what order should you do the activities to complete the project as early as possible?

And how many workers will you need and how will you assign them activities?


What do we need to know?


Something like this…Activity Time needed to complete

Substantial repairs to the roof 8 days

Internal structural work 4 days

Electrical work 7 days

Plumbing 6 days

Installing a new kitchen 3 days

Installing a new bathroom 4 days

Garden 5 days

Plastering 4 days

Internal decoration 5 days

Fitting carpets 1 day

Outside paintwork 5 days

usedBusinesses, hospitals, schools

(in fact anywhere where complex projects take place)


Over the next few lessons we will learn how to approach problems of this type…
