With the OpenEdge Advanced GUI right around the corner (well, coming soon anyway), I thought that it was appropriate to start a discussion on one of those four application pillars - Features. As you may recall, I defined features as those characteristics of the software that aid in usability but are not domain specific. Most features are somehow related to user interfaces - navigation systems, look-up systems, sizing attributes, etc. But there are others: Reporting, security and access, personalization and customization methods, etc. For this discussion, I'll concentrate primarily on the user interface features.
There are a number of subjects that we need to cover in here, so I will likely spin these out through multiple blog entries. And if anyone else has ideas or questions, we can weave them through the process. Here's the most important place to start: To be effective, any feature that you put in your software must meet these rules:
With those rules firmly in mind, let's look at how to think about and design features for your application. It's tempting to jump right in to the particulars of a given feature or a given UI, but here's something I learned many years ago:
There's an important idea buried in that statement. For functionality, we tend to look to customers, domain experts, and direct industry competitors. For features, we should look at prospects and the wider software industry. The applications that we tend to build don't directly compete with Outlook, but we will compete with Outlook for the perception of our software in the user's eyes.
This makes it more difficult to design and implement good application-wide features. We're out of our comfort zone. So here's a method for prototyping and implementing features that I learned many years ago:
Those last points may seem a little harsh, but inconsistency inevitably leads to application degradation. And none of us want that.
That's enough for this first posting on features. We'll follow it up by getting in to the various types of features and how to think about each as you use the new Advanced GUI to build a new application or freshen up your current application.
