Questions?


Case Study: Chicago Public Schools

  • Consider the following:

    • Preliminary Problem Statement

    • 3 System Improvement Objectives


Case Study: Chicago Public Schools

  • Customer Profile

    • Third largest school district in US

      • 407,000 students

      • 665 schools

      • 22,000 classrooms


Case Study: Chicago Public Schools

  • Problem Profile

    • State Legislature mandated attendance keeping

      • Every hour

      • AWOL students identified

      • Parents and central office notified within 15 minutes


Case Study: Chicago Public Schools

  • Project Profile

    • Three vendors working the solution

      • Hardware

        • Large well-respected ‘big iron’ provider

      • Application

        • Focused on education suite

      • Platform

        • Well-known O/S + database


Case Study: Chicago Public Schools

  • Project Profile

    • Centralized Database

      • Server in each building

      • PC in every classroom


Case Study: Chicago Public Schools

  • Project Status

    • Symptoms

      • System overwhelmed

      • Hardware ‘locks-up’

        • Teachers cannot always connect

        • When they can, attendance takes 5 minutes


Case Study: Chicago Public Schools

  • Customer Unhappy

    • Vendors blaming each other

      • Hardware vendor

        • “we host applications much more complex than this”

        • must be application


Case Study: Chicago Public Schools

  • Customer Unhappy

    • Vendors blaming each other

      • Application vendor

        • “we’ve never seen this problem before”

        • must be the database


Case Study: Chicago Public Schools

  • Customer Unhappy

    • Vendors blaming each other

      • Platform vendor

        • “we can write millions of transactions a minute”

        • must be hardware


Case Study: Chicago Public Schools

  • Perfect opportunity for a ‘great’ project

    • Absolutely messed up situation

    • Customer ready to throw away solution and sue

      • First time large district placed PCs in all classrooms

      • Project had ‘failed’


Case Study: Chicago Public Schools

  • Task: ‘Fix it’

    • Six weeks until kids show up again

  • Thoughts

    • Who are stakeholders?

    • What are their motivations?

    • Who has the most to lose?


Case Study: Chicago Public Schools

  • Problem, Opportunity or Directive?

    • Why?


Case Study: Chicago Public Schools

  • Scope

    • Questions to ask?


Case Study: Chicago Public Schools

  • Scope

    • Questions to ask:

      • What kind of time, money and resources are available to reach a solution?

      • How will we know we have a successful project?

      • What has been done so far (‘gimme some history’)?


Case Study: Chicago Public Schools

  • Problem Analysis

    • What to do here?


Case Study: Chicago Public Schools

  • Problem Analysis

    • Determine

      • What are the symptoms the system is overwhelmed?

      • What are potential causes?

      • What is the root cause?

      • What are customer’s improvements objectives?


Case Study: Chicago Public Schools

  • Problem Revisited

    • Attendance-taking is a bottleneck

      • Taking way too long or not being done

    • Users frustrated

      • Central system often busy\unavailable

      • Process takes 5 minutes or more

      • School board and legislature applying pressure

      • 15 million dollars spent already…make it work


Case Study: Chicago Public Schools

  • Requirements Analysis

    • Determine

      • What does the system have to provide?


Case Study: Chicago Public Schools

  • Requirements Analysis

    • Determine

      • What does the system have to provide?

        Collect attendance hourly to identify AWOL students


How do we improve our odds of success?


Case Study: Chicago Public Schools

  • Solution Review

    • Issues

      • Application architected for 10-15 simultaneous users

      • Did not scale to 22,000 users


Case Study: Chicago Public Schools

  • Solution Review

    • WHY?

      • Too much simultaneous work

      • Poor design of application wasted ‘trips’ to database

        • Loading class roster (every hour)

        • Updating Central database (every hour)

        • Looking at individual student trends (every hour)

        • Loading a charts/graphs


Case Study: Chicago Public Schools

  • Solution Review

    • Other Issues that were resolved

      • Application updating individual records immediately

      • Application had business rules on the database

      • Did not direct traffic in middle-tier


Case Study: Chicago Public Schools

  • Solution Review

    • Fixes

      • Application re-architected: 1 trip to central server

        • Roster cached on classroom PCs

        • Updates queued at central server (asynchronous)

        • Attendance trends not sent back automatically

        • Notification sent to local school office first

      • Student updates

        • Better management of individual transaction locking
