•  Messaging Exception •  General/Speci!c Code

•  ErrorEvent & ErrorManager •  Synchronous/Asynchronous •  Client/Server roots

LCDS Messaging & CTI Best Practices

CTI pitfalls

•  Phone Hardware differences and con%gurations issues •  Dev versus Prod •  Avaya phone versus Nortel phone

•  Load/stress/endurance test early

•  Sockets consumptions •  ulimit

•  $reads consumptions •  Use LCDS NIO (or RTMP) channels •  Use LCDS Message %ltering •  And eventually leverage server side messaging/queueing technology

•  JMS / AMQP (MRG)

LCDS Real Time Messaging helps

•  Reliable Messaging

•  Message thro%ling

•  Channels and Endpoints –Choices, choices

•  Edge Server

•  Message "lters

•  Message priority

Distributed Agile Offshore process

Paris / Brussels Bucharest USA

Edinburgh

Hendrix : Distributed Agile offshore process

o  Don't Underestimate the Culture Gaps

o  Separate Scrum teams by functionality not activity

o  Collaboratively agree on the De"nition Of Done

o  Collaboratively evaluate and manage the technical debt

o  Get multiple communication modes working early o  Expect to need more documents

Use wikis to contain common information

o  Make Short Iterations

o  Produce Customer Test Data & Test Scripts Early

o  to Help Understand the Requirements

o  Use Continuous Integration to

o  Avoid Integration Headaches

o  Get Early Feedback on Functionality

o  Allow Early functional and performance tests

o  Monitor your technical debt
