Why industrialize PHP ?

8. 8PHP at Orange, the keys for industrialization – 2010
Why choose PHP ?
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...

PHP Industrialization is not only a question of IT skills.
(Industrializing a technology on a large scale is also related to people and finance).
Be sure whether development should be done in PHP and then be able to
Support the project throughout its life cycle
Accept to share your work, your source code
Accept that your source code is to be audited
Follow the recommendations in terms of tools and development rules
Change working methods, more agility,
Increase PHP skills, learn new technologies…
Value the work of PHP developers and interest of developing applications in PHP
 Create a real community of php developers in the company
 Trust with each other and accept to change

12. 12PHP at Orange, the keys for industrialization – 2010
PHP Industrialization is not only a question of IT skills.
(Industrializing a technology on a large scale is also related to people and finance).
Industrialize the workstation of PHP developers, methods and tools they use
Industrialize the test strategy
Build normalized infrastructure to cover nearly all PHP applications requirements
Reduce the recurring costs for the project
Contracting with vendors for support including maintenance,
patches and software changes.
Create different skill centers to meet projects needs
Invent new processes
Develop tools to facilitate and simplify trading between different players
working around PHP technologies
automate routine tasks, accelerate production of PHP applications
Implementation Process simplified and optimized to obtain a hosting environment
For the company, industrialization of PHP has a real cost
But If we do it well, there is a real ROI

Workshop #1 : Identify
Workshop #2: Rationalize
Workshop #3 : simplify hosting
Workshop #4: Recommend
Workshop #8 : Communicate
Workshop #7 : Capitalize
Workshop #6 : Train
Workshop #5 : Support

16. 16PHP at Orange, the keys for industrialization – 2010
Workshop #1 : Identify
Build a repository of applications (PHP or not) developed outside the SI
construct a form describing the project in term of :
 Goals, project life cycle
 Application Hosting
 Version of PHP (or other technologies), name and version of database…
 Business Owners Contacts, End Users, Application Manager
Appoint people on each site to facilitate the referencing
Each application is assigned a unique identifier code
"Vestal” is the name of the repository for local applications

17. 17PHP at Orange, the keys for industrialization – 2010
Workshop #2 : Rationalize
Implement a new process for projects to ensure that :
 development is useful and fills a real need
 there are no other existing applications that already meet this problem
identify development teams PHP :
 avoid leaving isolated developers
 Take stock of knowledge developers
stop the hosting of applications on workstations*
 Vestal has listed more than 2300 applications, today only 500 are still in production
 More than 150 developers referenced
Migrate applications in the correct versions of PHP and MySQL
(Main database used )

18. 18PHP at Orange, the keys for industrialization – 2010
