What Are Design Patterns? Proven, Reusable Usability Solutions

Just back from speaking about cross-platform design patterns at the Oracle Applications User Experience (Applications-UX) training event in Munich, Germany (March 6 and 7, 2012). The Oracle EMEA sales audience (yes, the UX Samba is worldwide) heard all about how Applications-UX research and design expertise created these building blocks for a new standard in enterprise applications user experience, how they are used by Oracle's developers, and what they mean for Oracle applications users, customers, and partners too.

What Are Design Patterns?

Design patterns are reusable user experience solutions to common problems or tasks in enterprise software. Using design patterns means our internal developers have proven, easy-to-follow design guidance implemented with Oracle Application Development Framework (ADF) and Fusion Middleware (FMW) components. The development process can scale, and the result is highly usable and consistent user experiences in our apps.

We can also make those patterns available to customers and partners who take Oracle applications usability even further by creating new usable solutions when they tailor our apps. Check out these Oracle Business Intelligence Enterprise Edition 10g and 11g design patterns, for example.

Design Patterns Explained

When speaking to non-UX audiences, it’s important to grab their attention early, speak in plain language, and use examples that they can relate to. In the case of design patterns, I could have told them about Christopher Alexander and A Pattern Language: Towns, Buildings, Construction (1977) and how design patterns became popular in software and web development. But they might not remember that or know how to apply it!

A sales audience wants to know about a competitive message about how design patterns help apps users navigate a virtual world easily, and how this knowledge can be used by to develop and extend usable apps. Using everyday examples that we are all familiar with, and adding in local flavors, gets the message across.

Item in shopping cart before signing in

Searching for and adding items to Amazon shopping cart before signing in. web site date picker

Using a DBahn date picker to automatically selects a date in the right format.

Google maps typeahead feature in search fields

Typing add in Google Maps is faster that selecting options from a list of values or waiting for search results.

So, to help illustrate, I used the “lazy registration” (that is, you can do your shopping and sign in or create an account later) on, the date picker on the Deutsche Bahn web site, the typeahead feature in Google Maps destination search, and a few other well-worn patterns that we now use on the web without even thinking!

Looking forward to the next opportunity to tell the Applications-UX design pattern story and to finding local examples that work for the audience too.

Oracle ADF Enterprise Application Development--Made Simple: Review and Opportunity

The holidays are a great time to catch up on required reading. I’ve just finished reading Sten Vesterli’s (@stenvesterli) book Oracle ADF Enterprise Application Development--Made Simple.

Oracle ADF Enterprise Application Development--Made Simple

This is a super book about the Oracle Application Developer Framework (ADF) using with the (recommended) Oracle JDeveloper IDE, communicated in plain language and easy-to-read style. Suitable for novice and experts with web development or Oracle Forms background, the book is written very much from the “let’s see great software running now” perspective.

All the essentials are there: the concepts behind ADF, the nuts and bolts of the components, and great how-to technical execution stuff. This is blended with valuable process insights and best practices right across the application development lifecycle, such as a proof of concept phase, planning, estimating effort, assembling a team, testing, deployment, and so on. Sten also includes information on how Oracle used ADF to create Oracle Fusion Applications. Take a look inside the book.

Of special note is a chapter on internationalization (i18n) and localization (L10n), something I am always relieved--if not delighted--to see, given my technology globalization interests. The market for Oracle applications is global and ADF has superb baked-in i18n and L10n capabilities: BiDi-enabled components using Start and End properties (instead of left and right), externalized text in resource bundles, hard-coding checks, XLIFF support, and so on.

Sten also brings usability into the application development process, with information on the importance of design (see the YouTube video below about the ADF Faces Rich Client Visio stencils provided by Oracle) and adding usability expertise to the team. This is a critical aspect to the success of any developed product or implementation (ADF-based, or otherwise). We (Oracle, working with partners and customers) continually up the Oracle apps community’s level of usability awareness and know-how that leads to successful outcomes for system implementors and consulting teams. We also curate customer and partner insights and experiences for the benefit of others too, notably through the Oracle Usability Advisory Board (OUAB).

UX Direct

Getting the benefits of apps usability to developers and implementors is what our UX Direct consulting service (featured at the October 2011 OUAB meeting) is about.

UX Direct

UX Direct take the superb out of the box functionality and flexibility offered by Oracle’s apps, matches it with Oracle UX expertise, and enables customers to accelerate their apps usage to the next level of user performance. You really don’t need special resources or teams to do it (but if you have them it’ll work too!), just UX Direct’s service and resources explaining usability benefits to implementors, showing how to find end users, gather their requirements and keep them engaged throughout the implementation process, what usability best practices and design resources to use, how to measure the results, and demonstrate ROI.

Using the UX Direct service's know-how and examples about Oracle apps tailoring opportunities (personalization, customization, extensibility, localization, and so on) delivers benefits of improved adoption rates, increased user productivity, lower training and support demands, and the satisfaction of knowing employees end their day happy with the app.

Develop Those Usable Apps Now

Watch out for more about the UX Direct service offerings from Oracle soon. In the meantime, I’d encourage you to read Sten’s book and take your apps to the next level of usability by using his work along with the Oracle ADF Rich Client User Interface Guidelines.

Incidentally, some folks asked me where the Browser Look and Feel (BLAF) guidelines used with the Oracle Applications Framework (OAF) for EBS are? They’re available on OTN here.
