EXPLORATION AND MINING (EM) BUSINESS REFERENCE MODEL


GMSI

History

•Gartner Mining: 2007•Proposed an industry collaboration•Resulted in the establishment of EMMMv


GMSI

Why?

The objective of EMMMv ( the Exploration, Mining, Metals and minerals

vertical) is to:

realise sustainable business- value through collaboration around a

common operating model and, by so doing, enable its members to

put their Business-IT investment into areas of differentiation versus

standard operating practices and support vendors in their delivery of

technical and business solutions to the industry.

“From the boardroom to the rock face”


GMSI

EMMMv

Established formally under the auspices of The Open

Group in 2008

Vision, Charter and product portfolio defined

Priority: Business Reference model

Iterative approach

What has GMSI done with the Model?

• Replace our Mining Value Chain circa 1998

• Absorb the EM model into our Business Reference Framework exercise – focused architecture process

• Expand the detail by mining method to L3 and in some cases L4

• L0-L2 – generic; L3 mining method specific; L4 client specific; L5 developer conversation

• Add to base of accumulated L4 & L5 info
