PARTIAL DRAFT *** This display is for functional clarity, not realism. ***

PEMS (Pocket Event Management System) manages relationships and communication between any school participants who have a smart phone using a simplified version of the industry standard Incident Command System (ICS).


  • Elementary school administration
    • Maintanence
    • PTA
      • Hot lunch program
    • Grades
    • Teaching Positions
    • Students
    • Neighborhoods
    • Emergency
  1. The above lables are “categories” that describe roles.
  2. A resource is a person, place, or thing.
  3. Resources can be in multiple categories / roles.

Hurt child – Pretend Blair falls and breaks an arm…

  • Admin
    • Teaching positions
      • Teachers
      • Aids
      • Volunteers
      • Yard Duty
        • John
        • Sally
    • Students
      • Alice
      • Blair
    • Emergency
      • Ambulance
      • Firehouse
      • Police
  1. John, on yard duty, sees that Blair has a broken arm.
  2. John selects “Blair” and changes her status, location, adds a note, “broken arm, bone showing”, and then updates the resource “Blair”.
  • Blair
    • Status
      • Absent: sick
      • Absent: vacation
      • Present: fine
      • Present: sick
      • Present: hurt minorly
      • Present: hurt severely
    • Location
      • At school
      • Upper Playground
      • 4th grade classrom #33
      • Lunch
      • Latitude and longitude
      • Other
    • Is stewarded by (all resources have cascading “stewards”)
      • 1° Parent: Polly
      • 1° Parent: Dan
      • 2° Grandparent: Sally Smith
      • 3° Neighbor: Lori Dom
    • Emergency Records
    • Homework
    • Classwork
    • Notes: ____”broken arm, bone showing”_____
  1. When “Present: hurt moderately” was updated, a text was sent out to:
    1. The local firehouse since they are part of the system and have preferences that trigger on “moderate” and or “severe hurt”. They now have access to Blair’s medical info on file with the school,  know where to go, and what to expect in minimal time.
    2. John could also attach a photo if the break was minor to let the experts decide if they should come, or just have Blair driven to the hospital by her steward.
    3. Blair’s 1° and 2° stewards (and emailed, etc. based on preferences). They can text John, and also continue to get all changes in Blair’s status.
    4. The administration, nurse, and Blair’s teacher are also texted.
    5. The custodians are also notified in case fences are to be opened.
  2. 80% of possible wanted info is already present and in the context of the node / role. If more location detail is needed, maybe the class is on a field trip, John could quickly choose the latitude and longitude coordinates offered by the phone. And or would just select “other”, add enter a description. This illustrates the flexiablity of the system: Unless there is a good reason to be more specific, location is normally just “At school” because there is no reason to track people.

Earthquake (big, roads affected)

  • Admin
    • Maintanence
    • PTA
      • Hot lunch program
    • Grades
    • Teaching Positions
    • Students
    • Neighborhoods
      • Burton Valley
      • Sarinap
      • West BVE
    • Classrooms
    • Emergency
  1. As soon as the shaking stopped, each teacher (or aid) would update students status, and the status of their classroom.
  2. In fact, all stewards could quickly update the status of the resources they steward at the same time. Bottlenecks are minimized.
  3. PEMS is low bandwidth.

After a few minutes, planners have a good idea of damage and can start to make decisions because views of  automatically summarized results is a few clicks away.. For instance:
Resources not updated within past 5 minutes

  • Teaching positions (3)
    • Sally
    • Frank
    • Tim
  • Students (5)
    • Larry
    • Molly
    • Trina
    • Sam
    • Jim

Kids typically line up on the black top via classroom. If planers determine it is best to send kids to their neighborhoods, organizing and updating everyone’s status only takes a few minutes because kids are already resources of their neighborhoods.

(more soon)


  1. Nice job, Jeff. What is in place now for ICS in various towns and counties?

    See number 6. spell “explainable”.

    Love, Jane

  2. Thanks Jane! As far as I know, current implementations of local ICS’s are proprietary, and expensive (> $100,000’s).

    Love, Jeff
