Introduction

Haim Mousan SCM & ALM/BI Tech Lead Intel Firmware Department (~600 people, 3 Geos)

Responsible for delivery most critical Intel Firmware IPsThose 2 IPs integrated in all Intel

PlatformsThe views expressed in this presentation are my own. I do not speak for Intel and do not represent Intel at any matter. I’m here to share my own private experience with SCM, Perforce usage and integration within our team in Jerusalem.

Problem Statement – 3 years ago…

Unstable coding environment with IBM ClearCase Unbearable Performance and Usability Issues Many dozens of methodologies Development productivity loss Zero integration with other ALM tools “Where is my data?” user complaints 3 people supporting ClearCase Massive increase in Intel’s Projects expected (X6)

Key Messages

Scalable and usable solution for firmware/software is a major challenge

BI and full data traceability are breakthrough capabilities for any SW team

Robust Source Control Management tool integrated with ALM is no longer a theoretical concept

Can be easily adopted by any SW team within several weeks
