Intro

• Apple first introduced the concept of Server
  Driven User Interface (SDUI) WWDC 2010. Server
  Driven User Experience is also known as data
  driven app design that helps to remotely update
  the native user interface and data structures in
  the already deployed mobile applications
• Its a fact that a great user experience is
  resulted from dynamic content that is enhanced by
  dynamic presentation. This is what SDUI framework
  does- make UI presentation easier by eliminating
  the need of frequent updates for an application.
  SDUI framework is much like a Model-View-Presenter
  that assumes the functionality of the
  middle-man.

Challenges in App Design

• There are two fundamental challenges most of the
  app companies and developers are facing everyday
  
• Balancing act between MVP (Minimum Viable
  Product) App updates
• Mapping user profiles to App UI

App MVP A Boon with a Time Factor

• Lean development is a phenomenal proven beyond
  doubt. Product owner decides what will be the
  Minimum Viable functionalities to be added in an
  App to get user validating the idea and
  re-iterate the same sprint by sprint. Thats
  brilliant and works seamlessly and real-time for
  webapps. But for native Apps, it has a speed
  breaker (and sometimes may be as long as the
  entire sprint). This speed breaker is App
  approval process and app update from end user.
  App approval process for iOS takes avg. 2 weeks
  and if you are not lucky it may go well beyond
  that. Post app approval, the app is on the mercy
  of the end user to fire the update. Firing the
  update is becoming a rare event considering an
  avg. user installs 50 apps in the device and most
  of them keeps busy users notification bar for an
  update every alternate week.

• Approval pain points are virtually non-existence
  for Android platform but the user updating the
  app regularly is even a bigger problem in Android
  platform compared to iOS.
• So the app is ready with the learning just added
  in, but nothing can be done till the speed
  breaker is passed by. Put this in context of
  webapps and you know what a terrific waste of
  time and energy till you figure out actual usage
  statistic from end users.

Profile based App UI

• There are various challenges for developers to
  create outstanding Apps in just a short period of
  time. Among them, there are several Apps that
  have the same business logic, but need specific
  UI changes as per the requirement of the
  end-user, especially in the B2B domain.
• Briefly stating, there is always requirement of
  mapping apps UI with the relevant end-user. This
  eliminates the redundant development of similar
  apps from the scratch each time with only minor
  UI changes. Ultimately, designing and developing
  the Apps according to the end-users need and
  making them more compatible to work on for every
  single user profile is still the biggest question
  for developers which so far has not been
  perfectly answered..

Solution SDUI

• The Server Driven User Interface framework viz.
  SDUI literally makes the above challenges
  obsolete by allowing dynamic UI updates as well
  as profile driven UI for each user. SDUI is built
  and deployed with just one code base logic and
  is applicable for each of the UI releases, while
  eliminating the need of frequent updates for the
  Apps.

• The actual solution is described below

• SDUI maintains a UI database that parses UI data
  in the JSON and further stores it on a web
  server. Since the iOS native app calls
  appropriate JSON file through the web server, the
  UI of the App is as dynamic as the content
  itself.
• User profile specific UI can be catered based on
  the login credentials, the web server calls the
  user information from the web server. In this
  process, the image and contents are fetched and
  parsed in the application in JSON itself.
• Finally, with the help of SDUI kit framework, the
  App displays the final updated UI for the end
  user.
• The key highlight of this solution is that the
  main business logic remains same for any of the
  User Profiles thereby saving considerable amount
  of time that is required for app updates. With
  the enhanced profile user interface, the user is
  able to view the products or items that are
  assigned to selected profile.

Highlights

• Manage multiple UI releases without pushing app
  updates
• Single business logic with multiple UI formats
• Flexible approach for developers and end users
• Elimination of minor UI updates

Why Azilens SDUI is Unique?

• While there are quite a few platforms available
  where developers (or even non-technical users)
  can design and publish their apps there is a
  need for a platform that can facilitate managing
  App UI with similar ease. Both startups and
  enterprises need to update their UI or better
  customize their UX in order to maintain their
  traction matrices.
• The SDUI framework performs these relevant
  functions by going extra miles to meet the ever
  dynamic needs of the industry. The apps released
  through SDUI framework eliminate the need of
  redundant approval process. Instead it directly
  caters to the users as well as business real
  time. This ultimately results in the most dynamic
  and scalable app framework.

13
Wrap-up

• SDUI is aimed to create better and more personal
  experience for the end users while providing the
  developers the much needed customizing
  flexibility and agility in roll outs. With the
  huge spectrum of benefits to both sides this
  Approach is as promising as the Tech behind it.
