Technical Professional

Adrian Daniels photo.

Over the last 10 years I have helped many customers to design, configure and implement Software Configuration Managements systems. Previously I spent 10 years writing real time embedded software for the Power System industry. My current focus is around the exciting Jazz Platform. I am a keen advocate of Application Lifecycle Management and how it can really help customers to scale their development capabilities. I love technology, whether it be the latest electronic gadget, a new approach to the software development lifecycle or adding Electronics to my Mk1 Golf – each has its own challenge that helping to solve makes me tick.

An IT professional with 24 years experience, encompassing leading edge technology implementation, software sales and global team management. Glenn began his IT career shortly after finishing his A-levels as an IBM Mainframe operator on twelve hour, seven day shifts.

After a number of years at Sodexho Glenn joined Select Business Solutions, a case tool vendor as a presales consultant. Glenn’s primary activities at Select focused on UML/MDA, (Unified Modelling Language, Model Driven Architecture), where he was presenting jointly with the OMG around the world, he also became a leader in reuse initiatives with his experience of Component Based Development and initially component then asset level repositories. Glenn became the UK then World Wide Presales Manager at Select Business Solutions, then in 2005 he joined IBM to focus on MDA as technical professional. With 6 years working within IBM Rational, Glenn is now the Brand Architect team leader. This senior team of consultants are the presales solution architects for strategic named clients or partners for Rational UK. This role aims to transform client initiatives and challenges into a strategy and practical solution based upon IBM Rational capabilities. Glenn has been aligned to IBM partners, primarily system integrators for the last four years.

He organizes motorbike trips to Europe every year and is hoping to one day ride the Stelvio pass in the Alps.

Rational Channel Highlights – Solutions for System Integrators.

A blog on the world according to Rational UKI and Systems Integrators. This blog should be of interest to anyone providing a software development ‘service’ to clients, not just global systems integrators. The aim is to share some insight into what’s interesting in this market, the challenges and the solutions that make a difference. The hope is also to create an awareness about the vast ecosystem available to IBM partners to support them.*
