Gloria Ingabire, Carnegie Mellon University

OpenMRS is an existing, robust medical record system (MRS), and Ingabire is proposing some additional functions for it, called OpenMRS+. She was inspired to take on this challenge by her mother's history of diabetes and uncle's history of cardiovascular disease. If people knew the likelihood of getting a non-communicable disease, they might be more likely to take precautions.

Simon Brown, Coding the Architecture

by Jacob Tate, Mount St. Mary's University
Simon Brown taught us a lot in his session titled "Software Architecture as Code." From teaching us where Jersey is to how to extract architecture from code, Brown gave a riveting talk on bridging the gap between architecture and code. Diagrams for software architecture are often messy; one developer cannot distinguish another's way of thinking by looking at sloppy boxes and mismatched lines. Would we write our code this way? Our code does not map to the architectural views we created, and this is a problem.

Forrest Shull opened the session with a brief introduction to Open Systems Architectures (OSA), an initiative within the DoD, to make systems more configurable and adaptable than they are today. This initiative ties in with the Better Buying Power Initiative, which focuses on making systems more efficient and effective. It's about system architecture, but software architecture is buried within that. How do we make systems more modular, more open, and still deal with interfaces between the components when the systems are part of a community? How much to make open and how much to keep behind the wall are issues that this initiative must deal with. Each panelist gave a brief on their opinions of where OSA stands today and what its challenges are.

Font Llitjós began this conversation-style panel with a brief review of Design Thinking 101: "Design is not a product designers produce"; "design is a process designers facilitate." Then she introduced IBM's method, which includes four modes of design thinking: Understand, Explore, Make/build/prototype, and Validate/iterate.

Paul Boos introduced us to a little Japanese in his talk titled "Improving Architectural Refactoring Using Kanban and the Mikado Method." These methods have been employed by such companies as Toyota to drastically increase production speed while tracking progress. But how does this translate from assembly lines to software?

Rick Kazman, University of Hawaii and Carnegie Mellon Software Engineering Institute, and Humberto Cervantes, Universidad Autónoma Metropolitana-Iztapalapa
Design is hard. Architects need insight into types of architectural drivers, guidance on selecting design concepts, and what drives certain design decisions to make good decisions by considering these consciously. Architects also need an approach to negotiate with management and stakeholders better to make these good decisions. In this tutorial session, Kazman and Cervantes presented an updated version of the 2006 Architecture-Driven Design Method 2.0 to address these concerns.
