When deciding to build an App targeting more than one mobile platform, very often a business user may have to face a quandary of how the same will be interpreted and developed, by different teams for the same or similar experience outcome, across the platforms targeted.

Analogically this predicament is similar to a book author expecting a book to be translated with the perfect sense of the original book. If one translator has mastery over the original language and the other languages, into which the book is to be translated to, then that translator would be the most ideal one to be assigned the translation work.

Extending the analogy, if a business user is to target multiple mobile platforms, then it is best to be assigned to a development team which has mastered the art of tweaking Xamarin towards the targeted platforms – like iOS, Android or Windows. Xamarin saves precious development time of having to maintain only one code base for different platforms. This effectively translates to lesser development time, faster time to market from the conceptualization stage and therefore reduced app development cost while reducing the need for multiple versions to be maintained for the different platforms. So, that would be a key benefit of engaging SIERRA’s Xamarin development team.
