Adding Macros & Final touches
As you can see, there are 2 important macros in this dashboard.
#1: Capturing selected item details
Whenever user clicks on an item in the detail area to compare, there is a small macro running behind that tells us what item is selected so that we can trigger our calculations and conditional formats. How does it work?
Simpler than we think!
We use a macro called as Worksheet_SelectionChange.

Understanding Event Macros
There is a special type of macros in Excel called as Event macros (or simple events). For example, if you want to do something whenever user selects cell D14, you can use an event macro. Excel offers various events so that we can initiate certain actions when user selects a cell, clicks on a hyperlink, activates a worksheet, updates a pivot table or finishes some calculation etc.
In our case, we wanted to change the comparison options based on what is selected by user. So we use an event called as Worksheet_SelectionChange
When you add a selection change macro to any worksheet, excel runs whenever you select a cell in that worksheet. Lets look a simple worksheet selection change macro to understand this:
The code for above event:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
[valSelection] = "You have selected " & Target.Address
End Sub
The range valSelection is linked to text box that you saw in demo.
Event macro in our Customer Service Dashboard
In our dashboard, we have one additional challenge. We need to run our event macro only if one of the two lists (rndSel1 & rngSel2).
This is where we use an additional feature of VBA, Application.intersect() formula. This checks whether given two ranges overlap and if so, returns the region in overlap.
Lets look at our event macro:
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'This macro is triggered whenever any cell is selected in the Dashboard worksheet
'Step #1: If user clicks on a blank cell then do nothing
If ActiveCell.Value = "" Then Exit Sub
'Step#2: See if the selected cell is in left column
If Not (Application.Intersect(ActiveCell, Range("rngSel1").Cells) Is Nothing) Then
'If so, then call setOption1 macro
Call setOption1
'Step #3: See if the selectd cell is in right column
ElseIf Not (Application.Intersect(ActiveCell, Range("rngSel2").Cells) Is Nothing) Then
'If so, then call setOption2 macro
Call setOption2
End If
End Sub
If you examine the comments, most of what it does should be obvious.
#2: Showing & Hiding help messages
Adding help feature to complex dashboards makes life simpler for end users. So I always recommend it to my students. But how easy is it to add help?
Well, easier than you think. Just follow below steps:
- Add help messages to your dashboard using drawing shape > bubbles
- Once all the messages are added, just select all of them and group (right click > group)
- Select the group and using name box in Excel, give it a name, in our case the name is boxHelp
- In a new module, Write a macro (lets call it showHideHelp) to display and hide the boxHelp group.
- Now add a small text box with label “Help” on it.
- Assign the macro to this help text. (right click on the group, assign macro)
But what do we put in showHideHelp macro?
Simple, When user clicks on Help text, we will just toggle the visibility of boxHelp group using code like this:
ActiveSheet.Shapes.Range(Array("boxHelp")).Visible = Not ActiveSheet.Shapes.Range(Array("boxHelp")).Visible
The Not portion toggles the visibility, thus when you click on help button the help gets turned on if it is off (and vice-a-versa)

Future directions for this dashboard…
I am happy how this turned out so far. That said, we can make a few advancements to it like:
- Using Excel 2010 slicers to make the selection of items in comparison area.
- Adding ability to export dashboard as PDF or PPT
- Adding qualitative comments to dashboard (automated a la tweetboard or manual) so that managers can understand what caused the change.
- Adding customizable time windows. Currently the dashboard shows any 4 week window, but it can become even more powerful by adding custom start and end dates.

That's a great idea.
Maybe the planned End Date should be highlight more.
I don't know how it would look like (nor how to do it yet), but what if instead of finishing the bold line to the best case End Date, it finishes to the realistic End Date?
The idea is ok, I think other project management tools have this, already? Maybe not.
Gantt charts in my view are about the signal most unless thing in the world, theres no way you can look at one thats more that a little complex and understand what it's telling you. I'm going to write a diatribe on project management at some point, its one of my pet areas I think!! 😉
The issue I have with this chart Chandoo, is that Tasks need to be linked to each other, so they should inherit the uncertainty, which would mean the as you moved down chart the lines would be miles apart for later tasks, and you might have to add lots of lines for subsequent tasks to cover the various outcome of it's parents.
Having said that, for the high level board summary, it's a nice way to go, it it appeals to the management 😉
thanks Chandoo, great post.
Ross
Whoooa !!! That's a very clever idea Chandoo. I really love it.
I think i'll update my gantt project sheet with that idea soon (remember my template ?)
@ross : you can link start date to the end date of the previous task in your data. The only problem I still se is to which end date (real ? planned ? best ?) in order to have average amount of information.
If best end date, you'll tend to increase uncertainty at the end of chain, although if you link to real end date, uncertainty will be decreased too much, leading in both cases to wrong management direction.
Maybe planned till the task is finished then real will do the job ?
Hey chandoo, this looks good and this would definite add value in production planning / scheduling. Uncertainity in finishing a task is very high in production scheduling and this could give an insight or a bird eye view of possible shipments we can have....
I've always been frustrated by the limitations of gantt charts. Will definitely use this, I've always struggled with how to succinctly communicate the uncertainty of certain tasks without confusing stakeholders.
I like this, I think it's a very effective way of showing how a timeline can change and which parts of a project need close attention.
@Cyril / @Ross: I would intially link the the start date to the planned end date of the previous task, with the chart updating when a task has been completed to reflect the true end date.
Or what about giving a drop-down selection box to allow the user to see the chart based on planned/best-case/worst-case end dates?
Like the idea. Have found that Excel is more flexible than MS Project for graphical solutions. The "Best Case"\"Worst Case" metrics are theoretically appealing but once the project and\or phase commences their reliability diminishes. A chart like the above that showed Planned Start, Planned End, Replan End Start, Replan End Date, Number of Replans the Start and End Dates, and Actual would provide an active, actionable view of each task\phase. It would also highlight the areas which are riskiest.
It is always amazing how flexible excel can be.
My question is how would the chart show a scenario where the date moved up? If a task is dropped or the duration of the task is significantly reduced by applying more people or machinery to the task, the dates will move up.
The gantt chart has been around for a long time, but it is still quite useful to show progress.
Cheers,
B
I like the idea but seems bit complicated in case of long projects involving numerous activity.
Also, reading and explaining is required hence not feasible where plans are just send to audience for approval.
Cheers

Great idea Chandoo,
When I was reading this idea regarding delivery dates, another thought popped into my mind, how can you show the uncertainty with MONEY!!
In this case, applies to cost management or even a normal budget, you think?
Would Box Chart and Gannt Chart help to understand the best case, middle case and worst case when money is spend or planned with these three risks are involved?
I imagine that this chart could help people who write their budgets get a better understanding of risks affecting their spending.
Peter
Chandoo,
I like it. How would you display an entry once it has been completed (actual)?
Thank you,
Matt
From what you have shown so far I think that this box Gantt chart is awesome! I think that this could be an extremely useful tool.
I can't wait to learn how to make my own charts in Excel.
Will the methods that you are going to teach us work in 2003 as well?
[...] Firday, we proposed a new chart for showing project plans. I chose an ugly name for it and called it Gantt Box [...]
You need to read Eli Goldratt's Critical Chain. The uncertainty you are looking for should be accounted for in a project buffer. Not at each task level.
Further you should spend time understanding Agile Development. This would have you plan only in 1-3week iterations. This allows you to embrace changes to work not yet started, and for your customer to re-direct your course at regular intervals (after each iteration) throughout your project. keyword search: Agile Scrum
These items will show you that you are solving a tracking problem for something that you can entirely avoid!
