This is a guest post by Vijay, our in-house VBA Expert.
Hello Everyone,
This post shows how to make project risk maps using VBA. If you have modern versions of Excel (365, 2019 or 2016 with TEXTJOIN() function), see the Excel Risk Map Template page.
We all have some projects to manage every now and then and there are needs of various trackers that help us in gauging the progress of the same. One of the most important things are heat maps that quickly help us in visually displaying the names of the projects that need special attention and resolve issues that are impacting them.
So go ahead and grab a cup of coffee and read this article that would help you in creating a Risk Heat Map in excel (will use some double shot espresso in the form of VBA code) to help us to the target.
Before we begin – Data for Project Risk Maps
First of all we will understand what we are trying to create here by looking at the image below.
You would have seen a picture like this while managing project risks.
So today we will be learn how to create this in Excel to become more awesome in managing projects.
What is important here is how your data for the projects/entities being tracked laid out. We will use the Excel data tables [structured references] to help us here.
There is a Setup sheet in the excel file where we can add the names of the projects that we will use on the data table, as well as the Probability and Impact have been defined as data tables. This helps us in using their contents as drop down options in the data table.
Adding Named Ranges
We need to use the Name Manager to create named ranges to be able to use the data table columns as drop down items, this is show below.
- 1.Type this in a blank cell and then copy “=tblProject[Project]”.
- 2.Bring up the Name Manager by pressing CTRL + F3, or by going to the Formula’s Tab and clicking on Name Manager.
- 3.Click on New
- 4.Type the name lstProject in the Name box
- 5.Paste “=tblProject[Project]” in the Refers To box and the click on OK.
Repeat this process for “=tblProbability[Probability]” and “tblImpact[Impact]”
Now you can go the actual risk data table and select the Project columns first blank cell and put in Data Validation List here, choose List and put the Source as lstProject. Repeat this for Probability and Impact cells. You will only need to this one time for the first row, new rows when added to the table will automatically contain these settings.
After we have created the above data table, we need to add 3 columns to the right side where we will setup the calculation that will be used to update the risk map.
a) First Column is named as “ProbabilityScore” Since probability has been marked as “A, B, C or D”, we would need to convert this into a number. This is done by using the below formula.
=IFERROR(CHOOSE(MATCH([@Probability],lstProbability,0),4,3,2,1),””)
b) Second Column is named as “SearchString”
=IF([@Status]=”Open”,CONCATENATE(“x”,[@ProbabilityScore]^4+[@Impact]),””)
c) Third column is named as “DisplayName”
=CONCATENATE([@ID],” “,LEFT([@Project],20),IF(LEN([@Project])>20,”…”,””))
Understanding the SearchString Table
When creating the SearchString we are raising the probability score to the power of 4, this is what I have chosen you may select any number that you need. Below is the resulting matrix of numbers that we obtain by doing this.
The last columns in only used for trimming the name of the project to 20 characters of there is a big name, else the actual name of the project is used to display in the Risk Map.
Understanding the Code
So now we are ready to look into the VBA code that helps us in creating the Risk Map.
Public Function showRiskMap(inputRange As Range, searchString As String, dataRange As Range, separator As String)
Dim cntr As Long
Dim tempArray() As Variant
Dim tempDataArray() As Variant
Dim tempString As String
tempArray = inputRange.Value
tempDataArray = dataRange.Value
For cntr = LBound(tempArray) To UBound(tempArray)
If tempArray(cntr, 1) = searchString Then
tempString = tempString & tempDataArray(cntr, 1) & separator
End If
Next
showRiskMap = tempString
End Function
We are sending 4 parameters to this function which are
- inputRange – this is the SearchString columns data
- SearchString – this is a manual enrty such as “x257”
- dataRange – this is the Display Name column from where we will pick the name of the project to display
- separator – this is CHAR(10) which is a line break in case we have multiple projects falling in the same category
We are making use of Array’s here to pass the data from the Table column into the array and then a simple For loop to parse them and show us the results.
I hope you will enjoy this article and this assist in managing your projects in a much efficient way.

Great post. I can't vote, though, because the answer I want to put down is "it depends". As with all visualisations, you've got to take into account your audience, your purpose, technical skills, where it will be viewed, etc.
I'm with Andy: It depends. Some I would use, some I might use, some I won't touch with a barge pole.
Naturally I have comments 🙂
The dial gauge, though familiar, is less easy to read than a linear type of chart (thermometer or bullet). It's really no better than the traffic lights, because all it can really tell you is which category the point falls in: red, yellow, or green.
By the same token, pie charts are so familiar, people don't know they can't read them. Remember how long it takes kids to learn to read an analog clock?
Bullet charts don't show trends.
With any of the charts that have a filled component and a marker or ine component, it makes more sense to use the filled component (area/ column) for target, and the lines or markers for actual.

I voted for #6 even though I agree with the other comments that it depends.
The majority of the votes are for the #2, thermometer chart. I still have yet to understand what happens when you are above plan/goal, which was brought up in yesterday's post.
Also, I agree with Jon in that it would be better to flip the series and make the filled part the target or goal and the line or marker the actual.
I am also a fan of using text when appropriate if the data is among other metrics in a type of dashboard. Calling it out by saying actual and % achievement is a good option.
Another "it depends" vote. Are you just looking at one or are you comparing a number of targets with actuals? You didn't include a text box. The problem with sentences is that they can get lost in a page of gray text. A text box can call attention to the numbers and line them up effectively.
I'm with Jon: "Some I would use, some I might use, some I won’t touch with a barge pole" and I'm surprised that some of your readers voted for the last group.
Jon says:

Why does this make more sense? I like 6 the way it is, although I would use a heavy dash for the plan/target marker.
"It depends" is also my take. What I usually try to drill into my clients dashboard design is the fu ndamental difference between spot results (am I on target for this month) and long term trends.. I always try to create 3 different set of graphs to represent real perormance:
- spot results vs objectives
- cumulative results vs objectives
- long-term trend (moving average) mostly) to see where we're going

I totally agree, Bob. I would normally favour a line for the target and a column for the actual, you can see quite easily then which columns break through the line, then.

Thermometer charts: "Not appropriate when actual values exceed targets" - this is easily solved by making the "mercury" portion a different color from the border, then you can clearly see where the expected range ends and the actual values keep going.
People seem to knock gauges quite a bit in dashboarding, but trying to show comparison of realtime data between operating sites and targets for each site can easily be done with a bank of gauges that have the optimal operating points at 12 o'clock.
The human eye is great at pattern stripping, and any deviation of a gauge from the expected 12 position will quickly register with an operator and attract his attention. Using a colour background, or meter edge, will also indicate the sensitivity of a particular site.

[…] work laptop I have a favorites folder just dedicated to Excel charts. Its got things like “Best Charts to Compare Actuals vs Targets” and “Best charts to show progress“. I love me some charts […]
I am wondering how will the plotting work, for some of the targets which may have been achieved before time. E.g. for the month of Jul the target was 226 and the actual was 219. So the chart will show a deficit in meeting the target by 7 points but what if this 7 may have been completed earlier in month of June. So ideally it not a deficit.
