Interoperability

Interoperability is explained in great detail in chapter three. In a lack of words the text defines that interoperability is a conversion of data from a unique system to another unique system. A personal example for me would be: In my high school drafting class I designed a house using RoboCad and several years later transferred that information to AutoCad. The objective was to convert a set of 2D drawings from RoboCad to a single 3D drawing in AutoCad. Since there is no computer interoperability between the respective software products, then the mode of interoperability was my own labor of redrawing the 3D version in AutoCad from the printed sketches in Robocad. This mode of interoperability is severely inefficient.  

The text stresses that interoperability is of paramount importance in building systems because of the many disciplines it incorporates. We as a building society should focus on how well we can transfer data from one aspect of the building phase to another. Cost to design to construction to occupancy is an example.

So how can we improve this exchange of data between hardware and software? The text elaborates that in order to achieve more robust data exchanges it is imperative to create a standard in which the data is exchanged. In effect this standard who figuratively funnel multiple data sets into a single recognizable solution.

There are problems that arise from creating a standard of data exchanges. Fellow classmate David Morrison hits the nail on the head with his explanation. David Says’ “A company that does not provide as much interoperability is typically one who wants its standard / program to be king above the rest. Whereas a company that is looking for high interoperability would most likely be a company that wants its product to infiltrate the market.” Essentially if a common standard is the key to interoperability then a single entity must design the system. If competing entities are designing for their best interest then it defeats the purpose of interoperability.

An interesting dilemma arises from the concept of interoperability. In essence the only possible way to achieve 100% efficiency of data transfer is to eliminate the transfer altogether. This would mean that competition must be eliminated. For example we would eliminate the use of different BIM products and use a one single product. If Revit were the product we choose as a society then Autocad and other modeling tools would be abolished.  But since competition is imperative for market survival the interoperability is a science that must be researched and improved.  Prof. Mitchell hinted at the idea that the future will challenge our interoperability prowess when multiple systems (such as robots) will have to co-exist in a societal fashion.
