In a conference call Hasso Plattner hinted that things had not been going well during Apotheker's reign.
"A profitable company is a happy company and I will do everything to make SAP a happy company again," he added. "We are not unhappy but we have to be happier."
He also talked about the need to restore trust both internally and with the channel and customers.
"What SAP has to re-establish is trust between all partners, customers and employees. We have lost it here or there," he said.
Plattner added that the vendor had products around cloud, databases andmemory computing coming down the pipe which should help it win backsome customers lost to rivals.
"SAP has not forgotten you andmany successful systems cannot be changed overnight but we will doeverything possible to speed up upgrades," Plattner said to customers.
Apothekerstepped down following a vote of no confidence from the board, with thevendor confirming in a statement that he had left by mutual consentafter it decided not to renew his contract that expired in December2010.
As a result, the board has named Bill McDermott, currentlySAP head of field organisations and Jim Hagermann Snabe, who is incharge of product development as joint CEOs.
