For huge corporate, legacy applications we dont tend to have the luxury of re-vamping the UI after assessing the UX of the process that those apps support. However, just because there has been a lack of UX applied to the app in the past doesnt mean we shouldnt do so now for new features the business are asking for.

I'd hate to follow what they did in the past just for consistencies sake but at the same time UX consistency is important - we wouldnt want old screens to continue to be clunky & grey but new screens streamlined & blue.

In these 'legacy' circumstances, is the only way to apply UX to your new feature to concentrate on info & interaction design but maintain the current visual design - no matter how ugly or un-user friendly it is?

I have a few tips for you, having done this in the past:

  1. grasp the complexity of the business and UX logic of the page BEFORE you start working
  2. think about maintenance before you start your design process
  3. consider the level of flexibility and adaptation of UX in this legacy system
  4. introduce UX as a new layer and keep your current legacy interaction layer separate (if possible)
  5. integrate your change iteratively.

You can scavenge the internet for information. Companies like Paypal, Google, Uber and dropbox have done it before.

I agree with Rayraegah that you must think iteratively with legacy projects. I am heading up the UX and design of a similar legacy revamp.

Our product has two luxuries yours may not: 1. A suite of various products that do not rely on each other (users may use one or a handful of the 20 available, but not all of them) and 2. an infrequent usage per user (1-5 times a year).

Our product also has some drawbacks, which I'm sure yours shares: 1. Gigantic Frankenstein Syndrome (UI produced in chunks as necessary over 10 years, with very little mind for consistency); 2. Technically unsavvy users who will meet change with confusion, even if it is "more usable";

Given these luxuries and drawbacks, how we are going about changes is a dance between bold overhauls and unremarkable compromise.

We used a completely new product as a test ground for a much different visual UI. This was in the "bold overhaul" category. However, since the new look was only tied to a completely new product, there was no massive change for our users to balk at. The plan is for this new visual design to be applied to all products as they get redesigned. This kind of "pilot product" is a safe way to showcase new UI choices to internal leadership as well. Doing something like this calls for building internal alliances, so that when execs see something very different, everyone responsible for the project has each other's backs.

In a small project, I improved upon the UX using the old UI constraints. This is in the "unremarkable compromise" category. However ugly the UI is, a new visual style would look out of place. These kinds of projects I see as a fun design challenge (constraints are fun!) – to see how much I can change while staying within the bounds of what will be allowed.

Each project up for redesign needs to be weighed somewhere between these two, and building a consensus about the change with all involved is a good idea.

  • +1 for mentioning building internal alliances and picking a pilot project. Wish I could +1 again for constraints are fun! – LindaCamillo Apr 25 '14 at 14:38
