Capacity Planning - 2

PERT calculations helps us to calculate the tasks on how much time it took to complete. On further tasks how much time it is going to take to complete. In a project an event or task can be codified and put into the timeboxed event. With the previous resource how much time it took same can be calculated with the future event called as forecasting.

Not only forecasting also can be utilized to provide managers information how their team performing in each tasks also the report can be used to compare with the other teams.

But there is a challenge that how to complete all the tasks within the time. Here comes our another star CPM, Critical path method.

 

Think about you’re making a biryani at your home, for example, Saraswathi, Nisha, Gomathi are helping to prepare biryani

 

Saraswathi cuts vegetable and grind masala

Nisha goes out and bring oil

Gomathi going to prepare the biryani

So plan is this

1^st activity cut the vegetables 2 hours, 2^nd activity grinding masala1 hour, 3^rd arrange the dry masala 1 hour, 4^th activity going to shop 2 hours, 5^th activity prepare biryani which takes 1 hour

Start, 1^st, 2^nd, 3^rd and 5^th, finish in one line

Start 4^th, 5^th in one line, finish in one line

 Explained in CPM method, so 2^nd, 3^rd and 4^th and 5^th activity totally comes 2+1+1+1=5 hours

2^nd path has 2+1=3 hours

So 5 hours is in critical path

Why we need to analyze critical path?

Imagine everyone in above scenario is busy, some one wants to delay, who can delay or which tasks can delay. If Total hours of 5 hours, in this Buying oil can be delayed probably Nisha can go to the market after an hour also. There will be no issues in preparing biryani on time.
