Microsoft Project: 17 – Multiple Projects

by Mike Glen, MVP

This month we’ll take a look at how you can consolidate a number of projects into one master to allowresource levelling across multiple projects.

Setting

Once again, we need some projects to work with. I have prepared 3 projects; each one is for a

modification program for a different type of aircraft. No – you don’t need any technical knowledge about

aeroplanes! The projects could have just as easily been for cars, or ships or boats or TV sets or PCs or

even software programmes – I just chose aircraft from my Royal Air Force engineering background. Load

them by clicking here:

So we have a situation where each aircraft is coming to the maintenance hangar to be updated with a

series of modifications and repair modifications (eg: Mod 326 and R Mod 326). The mod programme is

different for each aircraft type and they all require 3 types of technicians, which I’ve called Airframe who

look after the nuts and bolts, Propulsion who look after the engines and Electrical who looks after the..

aaahh.. electrics! Some tasks, like preparation will require all 3 technicians, but some are the

responsibility of a single tradesman or a combination of 2. (In real life, each mod would be broken down

further into its constituent tasks – but I’m trying to keep it simple!) What the Maintenance Manager needs

to know is how many tradesmen will be required to complete the program and how long will it take (again

for simplicity I’ve ignored costs). Note that the Start Date of each aircraft project is different as they fly in

one per week. Spend a few minutes browsing through the projects to get a feel for the dates, durations

and the resource assignments. Also have a look at the Resource Sheet view to see the Resource data.

Note that (again for simplicity) I have assigned to tasks only one tradesman of one type and thus they are

all at 100%.

Resource Peak Units

Finally, so that we can have a before and after comparison, we need to see what the Peak Units are for

each resource for each project. We do this, for example for Aircraft A, from the Gantt Chart view. Zoom

to show weeks in the Timescale and center the view so that you can see the whole project.

Window/Split, click in the lower window and then select View/Resource Graph. Remember that to see

the graph, we need to select a task that has resources assigned, so click on the Preparation task as it has

all three resource types assigned. You should see a view like this:

This view will show that for Project A, there is a Peak requirement of 200% Airframe technicians (or 2

technicians)

If you click in the bottom left scroll bar, you will be able to scroll through the other resources, and for

Aircraft A you should see a peak of 200% Propulsion and 200% Electrical. Do the same for the other 2

aircraft to verify that you can see a peak for Aircraft B of 100% Airframe, 200% Propulsion and 200%

Electrical, and for Aircraft C: 300% Airframe, 400% Propulsion and 300% Electrical. OK? So what

happens if we try to multi-project manage by looking at all 3 Aircraft altogether? Can you predict the

outcome?

Sharing Resources Between Projects

The Maintenance Manager has a team of men available but he doesn’t know how many will be required

or whether he can even do the multi-projects with the resources he has available. We need therefore to

set up a resource pool and associate each project with that pool. With a resource pool, all the resource

information that resides in the pool appears in each project file that shares the pool, because the resource

pool will be linked to the projects. Whenever information in the resource pool is changed, such as a

resource rate, it can be transmitted to all the linked projects, and vice versa.

Create a separate resource pool

Open a new project file to contain the resource pool and immediately save it as “pool” (for this exercise)

ensuring that it is stored in the same folder as the other 3 aircraft projects. View/Resource Sheet to note

that there are no resources in our blank pool project. For the pool to be used, we must tell each project to

go to the Pool for its resources. We do this by sharing the resources from the pool.

[As an aside, at this point in my writing I had to break off and go out. In the open project, I went to

File/Save Workspace…/and gave it the name “ramps” (Resource Assignment and Multi-Project

Management) with the suffix mpw – Microsoft Project Workspace.

Then, when I came back to start again, I opened the folder with my projects and selected ramps and all of

the projects opened up as I had left them – neat eh?]

Share resources with the resource pool

Open the first project to share the resource pool. In our case, as all the project files are open, you can go

to Window and select Aircraft A, or use Alt+Tab.

Now Tools/Resource Sharing…/Share Resources…

In the Share Resources dialog, select to Use Resources From: and select the pool.mpp file

of 7




To see what the result is, go to the pool project again and see that Project has automatically filled the

pool’s Resource Sheet with the resource data taken from Aircraft A.

Repeat the sharing process for Aircraft B and C, and note that the pool is still showing the same three

resources.

So that we can return to this set up again, please save the workspace as ramps.mpw.

Working with Many Projects in One Project File

It is quite possible to manage each project separately or as multiple projects, but it might be better if the

Maintenance Manager could see all the projects in one view. We can do this by creating a master file.

Frequent work with a number of related projects may best be managed more easily by consolidating

them. There are several ways to consolidate projects, copy/paste them into a master file, insert them into

a single project file, or use the Window function to do it all for you. Any changes made (other than format

changes) to the source file appear automatically in the corresponding inserted project of the consolidated

file, and vice versa.

Consolidate open project files

Let’s try the consolidation using the built-in Windows functions. Open all the project files required for

consolidation. Select Window/New Window...

…and in the Projects: list, select the 3 Aircraft project files (you can use the Windows facility of Shift or

Ctrl click to make your selection of the 3 files all at once) and OK.

Notice that each of the 3 aircraft maintains its own ID task numbering and that the 3 project summaries

are numbered 1, 2 and 3. Click on the little minus sign to contract the 3 summaries, then

Tools/Options…/View tab select Project Summary task, then File/Save As… ramps, you should see a

consolidated file like this:

Note the start and finish dates of the 3 aircraft are maintained with a week’s gap between them. The

consolidated file also shows a Duration of 39 days.

Resource Requirement.

As before, split the screen, select the Resource Graph for the lower screen, and Zoom to weeks. We will

have to open one of the files (click the + next to the summary) and select the Preparation task to see the

graphs. Now we see a peak requirement of 4 Aircraft, 7 Propulsion and 6 Electrical technicians. (Did you

forecast that?) Not also that all the resources are overallocated as Project is using the default maximum

units (see the Resource Sheet view) of 1 man or Max. Units of 100%.

Multi-Project Management

At last we’re beginning to use Project for project management, as we’ve input all the data and Project is

giving us useful information back to us. As Project Manager, what can we read into these figures? Well,

the conclusion I’ve come to is that, based on the calculations that Project has made for us, the Project

of 7




can be done in 39 days Duration, starting on 3 Jan 05 and finishing on 24 Feb 05 – PROVIDING I have 4

Aircraft, 7 Propulsion and 6 Electrical technicians. If that is the situation, I need do nothing more than get

on with it! Please save ramps again so that we can use it next month.

ConclusionThis relatively simple exercise shows the principles behind consolidating a number of projects to be able

to multi-project manage. The setting up of each project, creating a resource pool and sharing each project

with the pool is the essence. Project will do the calculations for you and make visible areas needing

attention like the overallocation of resources.

Next Issue

In the next issue I plan to have a look some of the other ways we can consolidate projects, and then

discuss some ideas of how to manage these multiple projects.
