Answer came in the annual plan: «Product and Engineering will be split into two departments, to bring additional leadership strength to the organization and to rebalance the senior team so one person doesn’t need to represent both disciplines. We will invest further staffing resources in both areas, especially in historically under-resourced domains (data analysis and analytics support, design, operations support for projects, security engineering, and community support). This will enable our core engineering projects to launch more quickly and at a higher level of quality in the future than resources have allowed to date.» https://wikimediafoundation.org/w/index.php?title=File%3A2013-2014_WMF_Plan_As_Published.pdf&page=4
