When I worked for the power company, I liked to ride around town with my colleague Paul.
Paul was a troubleshooter, an on-call worker who hung out in his bucket truck, waiting for something to go wrong on the grid. While the job may sound like a cakewalk, troubleshooters were almost always busy. Once someone reported a problem, Paul would get a call from the dispatcher and then race to the location of a power failure. He would quickly locate where the failure occurred; radio in an assessment of the damage; and, if possible, fix the problem.
Many of the issues troubleshooters encountered were caused by tree limbs falling on the exposed lines, causing a short circuit and blowing a fuse. Another common problem occurred when unwitting squirrels would use the power lines as a convenient path from one source of nuts to another. (The squirrels usually didn’t make it.) Each time, Paul would uncover the burned tree limb on the ground, or find the fried squirrel, then figure out which fuse blew and replace it. Problem solved in most cases.
In other, more complicated situations, such as someone crashing into a pole, Paul would contact the dispatcher to send a line crew. Paul was often the point person, who determined how long the job would take. To make such an assessment, he needed to know everything about the electric network—the location of each switch, transformer, lightning arrester, and sensor; the asset sizes; and how the network was connected. Ultimately, he needed authoritative data from the company’s geographic information system (GIS). And what he needed most was access to up-to-date information.
Me, Myself, and My Maps
One day while riding around with me, Paul came upon a line switch that didn’t look right. There was no reported power failure, but he wanted to investigate it. He hesitated. He clearly didn’t want me—the boss— to see something. But I probed and he finally came clean.
Paul reached under the seat of the truck and pulled out a huge stack of papers. They were worn map sheets and feeder maps, which were either created from the GIS or original, hand-drawn maps. A feeder map shows the electric grid overlaid on a normal map of streets. The map sheets had very neat red markings all over them.
Naturally, I asked him why he kept a private set of feeder maps. He knew that I had been the champion of the company’s GIS project. He broke the news that many of the troubleshooters kept their own set of maps. They didn’t trust the mapping department or the GIS to keep the maps updated. Plus, the mapping department didn’t put all of the important stuff on the maps, such as some hazards. He figured that if he handed over the map sheets, his life and work would get more complicated and perhaps less safe.
I couldn’t blame Paul. The mapping department was carrying a large backlog of work. Often, when they printed a new map sheet, it wasn’t up to date. Paul and his fellow troubleshooters stopped giving information to the mapping department altogether because, to them, it was a waste of time. But the problem wasn’t only that Paul didn’t share vital information with the mapping department—it was that he didn’t tell anyone.
Not only did other troubleshooters—who covered the same area as Paul on different shifts—not have his intel, but the planners, maintenance people, and reliability engineers lacked access to data as well. Had they known what Paul knew, these other groups could have acted and potentially prevented power failures. Paul’s approach was narrow and related only to his particular job.
Breaking Data Free
Now imagine if the power company had adopted the ArcGIS platform across departments. With ArcGIS, when Paul would find a problem with a switch, he could pull up the feeder map for the area he was servicing, using his mobile device. Paul could then redline the problem area, document the issue with a note and a red flag, and take a picture. Done. From that moment on, everyone in the company who had access to the ArcGIS platform would also have access to Paul’s records.
And when Paul ended his shift, the next troubleshooter would know which issues and hazards Paul had encountered. In addition, back at the office in the maintenance department, a dashboard would show staff which assets Paul had serviced in the field. Anyone who had a vested interest in troubleshooters’ service data could update the core GIS.
However, there are only so many troubleshooters driving around the city with their bosses looking over their shoulders. There are millions of other people—city workers, residents, police, and firefighters—on the lookout for hazards. They, too, can contribute their observations to the ArcGIS platform. When people smell something burning, see a tree limb dangling too close to a wire, hear a bang, or see a spark, they can document what they observe with ArcGIS Online mapping tools. There is no waiting. Once third-party data is captured online, everyone connected to the platform has access to the information and can act.
ArcGIS and Access
The ArcGIS platform is, in effect, a system of simultaneity. I know—that’s a mouthful. Maps are the most powerful form of communication for telling someone where something happened. The problem with keeping mapping systems locked away in a closet is that they lose the quality of immediacy. When you interact with the ArcGIS platform, everyone—people like Paul and other troubleshooters, planners, and even nosy bosses—get to see important data on a map simultaneously.
When I think of the ArcGIS platform, I think of the three basic things it does, all beginning with the letter A. This story is about the idea of access—simply put, the ability to access information from wherever you are, on any device, and at any time.
The second A is awareness. This answers the question, what’s going on right now? It does this by bringing all kinds of data from a variety of sources into the platform. Look for my next post, on awareness. The third is the most strategic and, maybe, powerful of the A’s: analysis. That’s about connecting the dots and getting to the why of what’s happening. I’ll be writing about that soon.
