Slicers are my new favorite feature in Excel. Introduced in Excel 2010, Slicers are like visual filters.
A simple example of slicers:
Let us say you have a sales report (pivot) for multiple salespersons. Since you want to show the report by one person at a time, you used report filters in pivot tables to display this. But you find that switching between regions is a pain using the report filter.
Enter slicers.
Now, you can just click the region name to show the report for that region, like this:
Using Slicers to Switch between Scenarios Dynamically:
Now, we can use slicers creatively to make an interactive scenario manager in Excel, some thing like this:
This technique gives the same outcome as the Display and Select Scenarios using VBA article, but easier to implement
How to use slicers to switch between scenarios?
Step 1: Set up various scenarios in a table
You need to define various scenarios in a table, like this:
Step 2: Create a pivot table from your scenario data
Select the table you created in step 1 and insert a pivot table. Use variable name as row label and variable value in value field area.
Step 3: Insert a slicer for the scenarios
Select anywhere inside the pivot. Now, from options tab, click on Insert Slicer button. Click on Scenarios field to insert a slicer.
Step 4: Create your model, in our case a break-even model
I will skip the explanation of model creation as that is not relevant here.
Once the model is set up, just refer to the pivot table for each of the variable values.
Step 5: Move slicer to Model
Go to the pivot table worksheet and Select the slicer, click CTRL+X to cut it.
Go back to your model worksheet and paste the slicer.
Step 6: Format the slicer
Excel slicers by default show an option to remove the filtered slicer. You can get rid of this button by,
1) Right click on the slicer
2) Go to slicer settings
3) Un-check Display Header option
See aside.
Step 7: Use the slicer to interactively switch scenarios
That is all, our smart scenario switching slicer is ready. Now, you can extend this in many ways. For example, you can write some clever formulas to handle selection of multiple slicers. You can compare between one scenario and another when more than one option is chosen from the slicer. So much more is possible. But I will let your imagination run wild.
Download Example Excel File:
I have made a simple example to demonstrate this technique.
Please download the file and open it in Excel 2010.
Examine the worksheets “Scenario Pivot” and “Model” to understand how the slicer is setup and how this works.
Do you slice?
As I said, Slicers are my new favorite feature in Excel. I have been using them as much as possible because they are simple to use and very powerful.
What about you? Do you slice often? What is your experience like? Please share your ideas and tips using comments.

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.

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,

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!
