October 2002:   Plan for compact and intermediate configurations finalized

	A plan for the compact and intermediate configurations will be presented
        to the JAO for approval.  This plan will include positions and
        uncertainties for the planned pad locations for ALMA suitable for
        investigation by those planning construction of the ALMA infrastructure.
        Based upon this configuration, the large Y+ configuration will be planned
        and positions provided suitable for investigation by those planning 
        construction of the ALMA infrastructure.  Owing to the more dispersed
        character of the largest configuration, some iteration based on actual
        investigation of sites chosen by remote designers will be needed.

February 2003:  Review of calibration requirements with science examples
                complete
	This review covers the calibration specifications for ALMA to achieve
        the science goals set for it by the community.  Specific science goals
        will be used to illustrate the specifications.   

June 2003:      Review of specifications for calibration items complete: 
                WVR, FTS, weather station
         This review takes the specifications written in February and translates
         them into requirements on how these specifications might be achieved.
         A detailed description of instruments needed, including such auxiliary
         devices as the WVR, the amplitude calibration system (dual-load, 
         semi-transparent vane, or other), any required bandpass or polarization
         calibration devices (a photonic transmitter in the subreflector, e.g.),
         a Fourier Transform Spectrometer, atmospheric temperature or other
         sounding devices and weather station requirements will be included.


June 2003:      Plan for Y+ configuration finalized
        A plan for the largest configuration will be presented to the JAO
        for approval, with the iteration between chosen sites and practical
        locations complete.

September 2003: Calibration strategy finalized
        The Calibration strategy is the baseline plan for the calibration of
        ALMA.  It will take the specifications and requirements already
        developed and confront them with the instrumental expectations to
        form the blueprint for calibration of ALMA observations.

December 2003?: Science aspects of operations plan complete, including
                core functions of Regional Support Centers
        The goals for science operations of ALMA, constituted by the ASAC with
        approval of the ALMA Board, are developed into the actual plan.

June 2004:      Plan for early science configurations complete
        During Early Science, there will be minimal population of the planned
        configurations.  The Science IPT will develop a plan for the placement
        of the Early Science antennas and for their movement between pads.

September 2004: Selection of WVR strategy 
        With tests of the latest generation of WVRs in hand, the Science IPT
        will develop a strategy which, in harmony with the calibration strategy,
        may be used.  This strategy will be developed through the use of the
        simulation software, along with advanced atmospheric modelling.

December 2004:  Review of tests of calibration strategies on
                prototype interferometer complete
        The prototype interferometer should begin operations during the early
        Fall of 2004.  The various aspects of calibration which may be employed
        on the prototype interferometer will be reviewed, including but not
        limited to amplitude and phase calibration schemes.

June 2005:      Science verification plan for tests and commissioning 
        individual components at the ALMA site will be written.  A plan
        for end-to-end science verification on a selected set of astronomical sources
        will also be written.  These plans will be finalized by this date.  
        These plans will draw upon experiences and results from the prototype 
        interferometer tests.       

June 2007:      Science verification of ALMA early science array with
                Bands 3 and x complete
                *** assumes Band 3 and at least one other Band commissioned***
        Execution of the plan established two years prior (above) will be
        finished.

xxxx 2008:      Science verification of ALMA Bands y and z complete
                *** verification of any bands not included in early science
                array ***
        Execution of the plan established prior (above) will be finished with
        a complete suite of frequency bands.

xxxx 2009:      Science verification of ALMA imaging quality complete
                *** need ALMA with at least 32 antenna's ***
        Execution of the plan established prior (above) will be finished with
        the half-complete array.
