STEM User Group Meeting 2006 proceedings

30 October 2006

25 current and prospective STEM clients attended the STEM User Group Meeting, held on 20–21 September at Clare College in Cambridge, UK. The audience enjoyed guest presentations from seven current users, as well as Analysys sessions on topical models and new software features. For the first time, several sessions were split into dual ‘tracks’, offering accelerated training for newcomers in parallel with master classes and technical detail for experts.

Topical models and new software features

The event kicked off with a showcase model from Analysys, examining how STEM can be used to structure a Market forecasting model for the full portfolio of services offered by a tier-one operator. The model includes services such as voice telephony and broadband, and examines churn effects from one operator to its competition.

Day two began with an interactive modelling session examining the business case for WiMAX on the urban periphery. This topic has been covered recently in a fairly detailed model examining the situation in France, which will be discussed in our January 2007 newsletter.

Guest programme

Michael Chang from Ericsson presented a STEM model representing Ericsson’s capacity growth solution, and then Oscar Gonzalez Soto, an independent consultant working for the ITU, gave a talk on ITU-D activities on planning for evolving networks.

Ruth Chatterton from Juniper Networks walked through a STEM model examining Network consolidation over MPLS, and Frank Haupt from ADC Services presented a Business case for distributed-antenna systems which combined Excel with STEM.

Guido Freiling from T-Mobile International discussed some tricky modelling issues concerning a Business case for SMS harmonisation and centralisation, and then Ross Mackinnon from Alcatel showed us a STEM-based Business model for GPON.

Finally, Manfred Illenberger from Siemens gave an interesting talk on Building STEM into an automated sales presentation tool, linking STEM results right through to PowerPoint.

Parallel tracks for newcomers and experts

Catering to the mix of experience levels present, three sessions were split into two groups:

A fast-track training exercise for newcomers, running over two sessions, used an unconventional example to focus on the essentials of business modelling. Steve Liput (Analysys) led a captivating exercise using STEM to Model a budget airline business. (This model is described in more detail in a separate article in this newsletter.)

Steve Wyatt (Analysys) ran the final newcomer session, talking through the current range of STEM licensing models, From desktop modelling to enterprise publishing.

Robin Bailey led the three technical master classes for existing STEM users. What’s new in STEM 7.1 presented and demonstrated new features, focusing on new snapshot charts, and tornado charts specifically for sensitivity analysis, as well as a new break-even function.

The technical intrigue continued with a look at Undocumented features and new development directions, which proved to be a surprise hit with the established STEM community.

The final session on Streamlining interfaces with Excel and portability took a close look at the Excel link generator (completed in STEM 7.1).
