SAP has promised that the long-anticipated set of key performance indicators (KPIs) for its controversial Enterprise Support Service, are coming soon.

The KPIs were first announced in November, following months of protest from some users over the vendor's decision to transition customers to Enterprise Support, which is richer-featured but more expensive.

SAP pledged to work along with SUGEN (SAP User Group Executive Network), an organisation consisting of user group heads from around the world, on the KPIs.

In a February interview, SAP executive board member Jim Hagemann Snabe told IDG News Service that SAP would "still need most of Q1" to finish them.

At this point, SAP is awaiting word from SUGEN on the KPIs, after which they will be finalised and released, according to SAP spokesman Saswato Das. "We are very close, we should get something very soon," Das said.

SUGEN representatives could not be reached for comment.

Observers such as Forrester Research analyst Ray Wang are eager to see the KPIs.

"Many of us had felt it would not be an easy task to come up with KPIs that could be agreed upon by users and SAP that would fairly show the value or lack of value with Enterprise Support," Wang said via email.

"It would not be surprising if they need more time to get the metrics right. However, many clients took SAP at face value and are awaiting SAP's progress in this area to determine their next move in contract negotiations. A lot is riding on this."
