PHP is Open Source, Interfaces very well with Mysql Large community of PHP programmers Easy to integrate with web pages PHP can run on both Unix and Windows PHP5 a fully object oriented language  A really efficient language for Web Applications Inside Orange Company ? Speed of development, low entry cost Many applications are built with PHP (more than a thousand) Many people are familiar with PHP ( more one hundred fifty developpers) For development of non mission critical IT projects => but business critical  An appropriate response to the needs of business PHP
  • 9. 9PHP at Orange, the keys for industrialization – 2010 Why Industrialization ?  Faster development, improved efficiency and productivity Improve the quality of development Increase the productivity of development teams Build reliable, adequate and sustainable applications Reduce the duration and the load for application testing Reduce the number of defects in the production phase Allow projects to share the same tools and methods Avoid each project to contract his own hosting environment Reduce application time and cost to go live Avoid an application to be developed several times in different places Provide a real and effective support to projects Inside Orange Company ?  An appropriate response to the needs of the business
  • 10. 10PHP at Orange, the keys for industrialization – 2010 Needs of industrialization…Few or no standardization, mutualization or reusability > No prescription development for PHP > Each project has to contract his own hosting SLA > Each project has to produce all the documentation to satisfy quality system requirements > No overview of the IT application life cycle > No development prescription for PHP (Rules, Method, Tools) > Slow delivery of platforms needed by the project Monolithic approach in IT development > High cost to each project, whatever its complexity (no segmentation or uses cases), > Minimum of 3 to 6 months to build platforms needed by the project, > Very poor support for “simple applications” (from an urbansism and technical point of view) > How to identify what are the most sensitive applications (ticketing, hosting crisis) ? > Poor efficiency and agility Applications Powered by IT : reliable but expensive and not business compliant > Are too slow for the business > Cost a lot of money > Are designed with heavy method Applications Powered by field developers : business compliant but not scalable for high usage > Are not reliable within high usage > Can’t be hosted with a good SLA > Are not designed with appropriate technology  Ensure that the IT world understands the needs of the Business, recognizes the use of PHP and makes all its power to "organize" and "mentor" and "sustain" its use and the resulting developments...
