Automotive and aerospace manufacturers are leading the way with the application of digital GD&T technology. Applying digital GD&T to frame rails, aircraft skins, fuselages and body in white assemblies, these manufacturers are able accurately simulate part and process variation and then take steps to control and reduce its impact on the final build.
Analyzing variation is faster and easier with access to CAD embedded GD&T
This is the general application of GD&T in a digital environment, but what are the reasons to promote using digital GD&T in the first place?

Excel can be used a for a lot of equation based applications. Many companies rely on it for their tolerance analysis; doing 1D stacks and stack-up analysis using Excel macros and Visual Basic code. For basic cases, this works great and can be a fast and effective way to get answers quickly, but as soon as products, models and requirements become more complex, Excel falls flat.
Integrated CAD tools give more accurate analysis results by incorporating additional influences
This means that your Excel answers might be misleading you, and can cause some embarrassing, and expensive, problems later on.
In what ways is Excel failing?
It is rare that all the parts in your product line up into a perfect linear line. Most often, there are parts arranged around your stack-up, and these part's tolerances will influence your linear stack. This 3 dimensional influence can cause more variation than you'd expect, and a 1D stack-up in Excel is not going to account for this.
Even with a linear stack-up, you can have angularity that will cause additional variation, or variation and issues unaccounted for in your Excel stack. These 3 dimensional issues are related to the geometry of the parts, and require a CAD-based approach to properly simulate and validate.
Not all scenarios can be calculated with an Excel 1D stack-up

Monte Carlo Analysis, using Monte Carlo simulation with tolerance variables and assembly processes, provides a lot of powerful outputs. Determining percent out of specification, critical features to quality, contributing parts and tolerances to out-of-spec scenarios, and more. These outputs can be used to reduce non-conformance in production, and thereby reduce scrap, rework and overall manufacturing costs.
As anyone who has worked in the simulation environment knows, that's the goal. However, getting there isn't always easy. Most teams responsible for creating simulations then provide that data to managers, quality professionals, plant managers, designers and other teams that have to use that data to make changes and decisions.
