Subject Progress Report for Requirements Organization SDD/SD
and Planning
Period 9/15 - 10/20/77
Filed on: ProgressReportl 0-20-77
Janus-I. -2 Requirements
A revised draft of requirements for the Janus first and second release has been published
and is currently being reviewed within SO. We intend to give these documents exposure
outside SD in draft form by November 4th. Current schedule for the programming release
of the Janus-I requirements revision in 1/78; Janus-2 requirements is 4/78.
Our objective is to create an explicit statement of requirements in areas previously treated
vaguely. A further revision of these documents will occur in late November. These revisions
will include exact information on software/hardware configuration rules and limitations.
D. Reil1y and V. Engstrom are both working towards additional requirements and design
definition. D. Reilly is providing detailed font/ROS requirements. V. Engstrom is
specifying the interfaces to foreign media.
Prototypi ng
Our efforts in user interface prototyping continues. The efforts have been invaluable for
people to use for evaluating proposals and alternatives. This is especially true where a lot of
qualitative judgement is needed. C. Irby describes the progress to date in his status report.
My plan is to give more exposure to these efforts at regular intervals for individuals in
planning and marketing. I will also request the group to prototype specific models to help
resolve some of the more global Janus issues (required display resolution, mouse dependency,
editing key use, etc.). Also, during the first half of next year, additional emphasis will be
placed in prototyping training models.
Meetings, Contacts. Plans
\Ve have established a good working relationship with Messrs. F. Haney, R. Johnson and
other personnel in planning. They will be given periodic demonstrations of prototyped
models and encouraged to work with our requirements people. .
Contacts and exchanges of information between technical personnel in SO and xes have
commenced. Presentations on the DO. Mesa, and tools have occurred. Presentations on xes
software user interfaces and interMals are scheduled. Fred Haney and I have started to
review objectives for an integrated Janus/lAS environment.
Contacts with Planning and B. Bebb's organizations started over the last few weeks for the
purpose defining specific requirements in the Janus/ROS interface.
Progress Report for Ucquirements and Planning; Period 9/15 - 10/20/77 2
I have. scheduled a meeting of SO/TPO/EOO technical personnel to review alternatives,
costs, and requirements for Janus display requirements. The objective is to gain a consistent
view of requirements for the UTFP and UTPD Janus displays. Any issues which can only
be resolved by prototyping or additional analysis will be scheduled. Ron Johnson will
attend. Hal Lazar concurs with the meeting's objectives and is supportive.
General
I have personally talked to a lot of people outside of SO about the SO'reorganization and
our objectives. People in planning and the TPO have expressed delight. They all feel SO is
logically structured.
