How many feel it would be easy to pass a tax levy in your district in the current economic climate? How many feel the need to stretch existing fi i l resources iin order d tto push h off ff a financial future tax issue? 2 How many feel additional financial resources will ill soon be b provided id d to you by b “the “ h State”? S ”? How many feel additional financial resources will soon be provided to you by “Washington DC”? How many feel that your district is likely at a “h h water mark” k” in regard d to its ffinanciall “high resources for the next several years? 3 What are we going to do in order to stretch h our current financial f l resources for f as long as possible? How do we find additional financial resources in order to fund much needed improvements within the school district? What process exists to help us become “more efficient” in our current operations? p 4 Introduce you to the concept of Lean Six Sigma and provide a brief overview of the methodology. Display examples of the deployment of Lean Si Sigma Six Si as a strategy t t to t increase i efficiencies / stretch financial resources for a public school school. 5 A combination of two business concepts: ◦ Lean ◦ Six Sigma 6 Based on teachings of Taiichi Ohno (Toyota). Specify value from the standpoint of the customer. Identify all the steps in the value stream (process); eliminating whenever possible those steps (waste) that do not create value. Re-examine the process again and again and again until a state of perfection is reached in perfect value is created with no waste. which p 7 The core idea is to maximize •The customer value while minimizing waste. waste •Simply, lean means creating more value for customers with fewer resources. 8 9 •Eliminating unnecessary steps in a process. process •Maximize value (customer) while minimizing g waste. 10 Based on teachings of Dr. W.

Through research, it was found that following the registration process in April 2010 and a submittal to the Early Childhood Center in May 2010 with a tentative class assignment for students students, transportation had developed an AM class roster of approximately 102 and a PM roster of approximately 103. Voice of the Customer - Critical to Quality (CTQ) Voice of the Business - Critical to Process (CTP) CTQs Critical Customer Requirements Balanced KG Class sizes class sizes (21 +/-2) +/ 2) Voice of the Business Don't increase cost of transportation Balanced KG class sizes for teachers effectiveness Business Issues Stay within budget Critical Business Requirements Don’t increase cost of transportation Better teaching Class sizes environment (21 +/- 2) CTPs Cost remains the same Balanced AM & PM class sizes Customer Issues Voice of Customer Lower class sizes for maximum educational benefit More conducive learning environment for students. ◦ ◦ ◦ ◦ ◦ ◦ ◦ Tim Atkinson, Director of Business Affairs Jan Holecko, Transportation Coordinator Greg Surtman, Surtman Director of Business Development (Tri-C) (Tri C) Dr. Jim Lloyd, ECC Principal Loretta McClelland, ECC Secretary Dr. Todd Hoadley, Superintendent Kathleen Fenderbosch, KG Bus Driver Means to Eliminate Source of Waste or Obstacle to Eliminating Waste Savings / Benefit from Eliminating the Waste Type of Waste Observations Overproduction Students that are double registered at O.F. and a nonpublic school.

Actions Recommended Adding a KG registration deadline 315 Could change class sizes and routes. Failure of parent OR school to Inform parents to notify notify transportation of change. transportation of potential moves. School forgot to notify transportation of new student Last minute route changes, no postcard for student Failure at school office Late entries/registration Last minute route changes, no postcard for student, added phone calls Carelessness of parent, newly moved into district Communication with school frequently. 80 40 None Communication to parents to notify transportation. School registration checklist. Adding a KG registration deadline 200 Registration Student withdrawn/doesn't enter Route changes Parent moved out of district or decided not to send the child to KG this year. Screening process. Adding a KG registration deadline 12 There were 49 students added to AM KG from April ‘10 thru March ‘11. Of the 49 students, 36 were new (29 over summer), 8 were due to street assignment changes and 5 were IEP placements. 40 Numbe er of students 35 30 25 20 15 10 5 0 New students Street changed IEP [49 added – 15 deleted (previous slide) = net gain of 34 to AM class] SUMMARY A large influx of new students occurred over the summer months Changes in street assignments to adjust the class sizes were made too early Class placements due to IEP’s had a minimal effect FUTURE PROCESS MAP Pre-registered students by June 15th Non pre-registered students. Student has IEP. Transportation assigns students to AM/PM based on street lists. ECC assigns student to AM or PM session. Adjust streets to equal class sizes AM/PM Daily il contact with i h Loretta/ECC Review class sizes. AM/PM even? YES STOP. NO Make M k adjustments in July. Loretta will communicate student enrollment changes daily (or as needed). After July, ECC will place students in am/pm classes to maintain a +/- 2 students balance. FUTURE IMPROVEMENTS •Add Pre-registration deadline of June 15th to reduce number of late registrations •Reinstate R i old ld street boundaries b d i andd wait i until il July J l to make k any adjustments dj with streets •Monitor Before/After KG daycare enrollment and use as a tool to adjust class sizes as needed •Daily communication on student enrollment changes with ECC/Loretta •Get feedback related to street assignments/routes from KG driver Generates sustained success Sets performance goal for everyone Enhances value for customers; Accelerates rate of improvement; Promotes learning across boundaries; Executes strategic change 57 Company General Electric JP Morgan Chase Annual Savings $2.0+ billion *$1 $1.5 5 billion (*since inception in 1998) Motorola $ 16 billion (*since inception in 1980s) Johnson & Johnson $500 million Honeywell $600 million 58 59 60 Olmsted Ol d Falls F ll City Ci Schools S h l Dr. Todd Hoadley, Superintendent (440) 427-6000 [email protected] thoadley@ofcs net Denise Tabar, Director of Food Services (440) 427-6440 [email protected] Tim Atkinson, Director of Business Affairs (440) 427-6000 [email protected] Tri-C Corporate College Greg Surtman, Director of Business Development (216) 987-5855 [email protected] 61
