Another Executive Change at Yahoo! (NASD: YHOO)

Yahoo! Inc (NASD: YHOO) has announced that said David Dibble, the company’s senior vice president of central technology, has resigned. The news is rather unexpected, but perhaps a sign of the continuing changes being put in place by the new management team at the California based web search giant. Dibble was not part of the tightly-knit team close to new CEO Marissa Mayer, although he did report to her.

Dibble was responsible for platforms, technology infrastructure, engineering, science and operations. He leads diverse, dynamic cross functional program management initiatives and ensures the right business case and strategic underpinnings are in place to make Yahoo!’s next generation products successful. Prior to joining Yahoo!, David was Chief Technology Officer at First Data Corporation, where he led large global organizations, oversaw the development of a comprehensive Technology Strategy and Governance framework and managed the company’s data center operations and application platforms. Prior to First Data, Dibble held a variety of technology leadership positions with Fidelity Investments, JP Morgan, Charles Schwab and FMC Corporation.

Dibble, whose resignation is effective today, is remaining with Yahoo as an adviser to Chief Executive Officer Marissa Mayer, the Sunnyvale, California-based company said today in a regulatory filing. Dibble is the second top manager to leave Yahoo recently. Last week, Media head Mickie Rosen left. Mayer continues to build the firm and place her own hand selected people in key positions close to her. The former Google executive has sought to return the firm to its former glory, and blaze a new trail for the once high flying firm. Whether she is successful in doing so, or becomes the next Ron Johnson is yet to be seen. We must remember that although it was a different circumstance, Johnson became Chief Executive for struggling retailer JC Penney (NYSE: JCP) to much fanfare and fired with enthusiasm. He left the firm in worse shape shortly thereafter the same way – fired, with enthusiasm. It will be interesting to see if Yahoo! and Mayer can find a different ending instead.
