At the Argonne National Laboratory (ANL) he was responsible for the system design, project management,
and internal systems coding for the Argonne Reactor Computation System (ARC), which, for the first time,
allowed the large programs required for reactor design to operate as a unified system on the initial
releases of IBM System-360. Significant developments within the project were:
- Use of program libraries
- Staged releases with formal reviews and test procedures
- Early use of PERT/CPM for software project management
- Development of an early object-oriented design capability
As a manager at ANL:
- Managed an internal consulting group that wrote software for laboratory projects
- Managed the systems software and capacity planning for ANL's Central Computing Facility
- Was responsible for training the users of the Central Computing Facility
- Formed an information management group that met ANL’s needs for business computing
At the Idaho national Engineering Laboratory, in response to the Three-Mile Island incident he :
- Brought project management techniques into the central computing authority in support of major
upgrades to the INEL computing capability for both business and science
- Formed a site-wide division of 75 people that served the needs of the experimental reactor program
of INEL with better organization and control over the software development process.
Left INEL to work in the minerals industry managing a software group working on a system to evaluate ore-
bodies and design open pit mines.
- Extended the design of the system to accommodate layered deposits,
- Won a worldwide competition for a Canadian coal mine against all major players in that field.
- Formed Just Associates, gained rights to the mining software, and (in 1984) built a PC-based UNIX
system to run the mining software.
Just Associates then moved its focus to providing systems for managing the maintenance departments in
plants and institutions of all kinds.
