 So you are managing a project, you have a budget and you are spending lots of money but do you really know how well your project is performing? 

Not Sure?  Well guess what you are not alone.

This article will introduce a couple of simple concepts to help you better understand where your job is actually at and how you can more accurately predict where it will end up.

 

Define your Budget and Measure your deliverable

To accurately understand where your project is at you need to define 2 things before you start, they are :

 

A Deliverable :

What are you delivering as part of this project. This could be as simple as managing a % complete for the whole project or breaking the project down into smaller deliverable elements which could have a range of different measures e.g. If your project was to deliver a new Road you may have multiple deliverables :

Item Measure Amount
Roading Lineal Meter 5,000
Kerb and Channel (Both Sides) Lineal Meter 10,000
Stormwater pits every 200m each 25


The above table defines the amount of physical work we have to do to complete the project.

A Budget :

It is pretty normal these days for most business to establish a budget before going out and commencing works. Budgets can be at various levels of details, but this example we will keep simple.

If we align our budget with our deliverables it will be nice and easy for us to understand what portion of the budget we have spent in trying to deliver each item.

 

Item Budget
Roading $5,000,000
Kerb and Channel (Both Sides) $200,000
Stormwater pits every 200m $150,000

Our budget could be as simple as the above.

 

How do you bring this information together?

For most project managers getting a cost report out of the accounts department or their cost system is reasonably straight forward. e.g.

 

Item Budget Cost to Date Balance
Roading $5,000,000 $2,000,000 $3,000,000
Kerb and Channel (Both Sides) $200,000 $50,000 $150,000
Stormwater pits every 200m $150,000 $75,000 $75,000

From the above information it is pretty clear how much of your budget has been spent, this is good but only half the picture. From the above information we do not know how much work has been physically completed.

For instance we have spent almost 1/2 the Roading budget but have we done 50% of the work?

Maybe we have had problems and our progress is slow or maybe we have just bought alot of materials upfront which we have yet to use. To understand these things we need to bring into play a measure of physical work completed.

Ideally we should be regularly capturing this measure of work complete daily / weekly / monthly. The quicker we can capture this with our costs the more accurately we will understand how well our job is performing. The key metric we are looking for is what is it costsing us to deliver each of the budgeted measurable items e.g. How much is it costing us per metre of road laid. If we can work that out that and we know how much road we still have to go we can estimate how much it is going to cost us to complete the road.

If our prediction indicates the job is taking a nasty turn we can start putting plans in place to try and bring the job back to where it needs to be.

 

Example of a report bringing together budget and measures
Item Measure Deliverable Budget Budget Rate

Cost to Date

Delivered to Date Actual Rate Balance To Complete Complete at Budget Rate Complete at Actual Rate Forecast Variance to Budget

 

Roading

lm 5,000 $5,000,000 $1,000 $2,000,000 1,800 $1,111 $3,000,000 3,200 $3,200,000 $3,555,200 -$355,200
Kerb and Channel (Both Sides) lm 10,000 $200,000 $20 $50,000 3,000 $16.67 $150,000 7,000 $140,000 $116,690 $23,310
Stormwater pits every 200m each 25 $150,000 $6,000 $75,000 15 $5,000 $75,000 10 $60,000 $50,000 $10,000

 The above report highlights the intial rate at which we expected to deliver the project for and it also shows the rate for which we are currently delivering work.

If we continue to deliver the rest of the job at the current rate it highlights the predicted variance to the budget.

In this case we can see that we are going to overspend on our Roading budget by $355,200 and save money on Kerb and Channel and Stormwater Pits.

 

Hopefully you find this conecpt useful and can put it into practice with some of your current projects and wow the rest of your Project Management team.
