For this and related reasons, we have embarked upon a sweeping we will do, and then doing what we said. This type of change at Gemini centered on detailed planning of what organizational cultural change is incredibly challenging, we can actually achieve with the resources we have but I am convinced it will reap many benefits in the available. We are effectively turning the tide from a best- future, once complete. effort operation dedicated to trying to please as many people as possible to a committed operation that will An important part of this cultural change involves only take on a certain amount of work, saying what incorporating meaningful accountability at many 4 Gemini Observatory www.gemini.edu GeminiFocus completion statistics and an over-all performance plot in Figure 2.

In summary, across all of the tasks programmed The 2007 Gemini Observatory into Gemini’s 2007 observatory Program Plan, a little Annual Progress under half were completed, and about 75% were either Report and Program Plan. completed or mostly completed. For our first attempt at this process I was pleased with the result but also recognize that we have much room for improvement. As Director, I take ultimate responsibility for our performance last year, which was a “mixed bag” in the end. During 2007 we identified a number of areas where better planning and, just as importantly, plan execution will improve these statistics in 2008 and beyond. The 2008 observatory Program Plan was generated through an exhaustive analysis of potential liens on our resources (cash, labor, time, etc.) and is predicated upon an overall goal of maximizing Gemini’s scientific product. In September 2007, roughly two dozen members of our management team met in Santiago to discuss levels into our plans and actions. As an international and formulate this plan after a couple of months of organization Gemini Observatory must account to intense preparation across all divisions. Representatives many entities but ultimately we are accountable to our from the Gemini Science Committee and Board were community for providing a world-class research platform also present during this planning retreat. The end result and to the taxpayers who make a publicly funded was a stark reminder of a “brutal reality” we must all observatory like Gemini possible. These stakeholders appreciate. In Santiago, with a vast number of pending need and deserve to understand our performance, as projects (beyond daily operations) displayed before our measured through a variety of metrics. managers and no way to find the resources required to do anything close to all of them, the core problem Part of the process of building accountability into our became clear to me. It has been right in front of us for culture therefore involves informing our stakeholders years but never have we quantified it so convincingly of our performance on many fronts. Toward that end as we did during our Santiago planning retreat. Simply we have recently posted on our Website, for the first put, Gemini’s staff was not sized to do much more than time, our Annual Progress Report (2007) and our 2008 sustain operations. We do not have a large stand-alone Program Plan summary (see Figure 2). Historically development team and our science staff is stretched too this report has been submitted to the National Science thin to make our very successful queue-based model Foundation per our Cooperative Agreement and, though work, with the “contingency” too often occurring in it has theoretically been a public document, it has never the form of staff research time. We have just enough really been made easily accessible to the community engineering resources to cover our needs, but the multi- until now. conjugate adaptive optics (MCAO) program substantially consumes what little margin is available. The arrival Consistent with our goal of increased transparency, of a new instrument that needs to be incorporated Gemini’s Annual Progress Report for 2007 was overhauled and commissioned into our observatory environment and linked directly with our 2007 observatory Program represents a significant perturbation in our resources.

Since the reporting period used this complex planning spreadsheet, I was reminded of a in this report is the U.S. federal fiscal year, and our comment from a sage former observatory director.

While nightly pending resolution of a variety of cost and resource operations at both telescopes are issues. And, while our science team has committed ongoing, planning to supporting commissioning of the Near-Infrared for the short- and long-term future Coronagraphic Imager (NICI) and campaign science in at Gemini has also 2008, dozens of other proposed tasks within the science become an ongoing process now that division have been deferred to no sooner than 2009.
