Brief financial background Income statement and EBITDA
Balance sheet and RONA
Ultimately, the success of the enterprise is seen in its financial reports, and sustained success requires enterprise leadership to pay attention to the financials. The goal of this short module is not to become a financial expert, but to understand how operational results contribute to financial results.

Income Statement
Net Income

Interest Expense
Net Sales
Cost of SalesOperating
Expense (SG&A)
Depreciation Expense
Income = Revenue Expense
Net IncomePre-tax
Operating Income
Gross Income
Summarizes financial transactions over a period of timea month, a quarter, or a year. Close the books to create the income statement.

EBITDA
EBITDA = Earnings before interest, taxes, depreciation, and amortization
Thought by many to be a more informative assessment of the enterprises performance in terms of generating revenue; interest is a financing outcome, not an operating outcome; taxes are beyond the control of the enterprise, depreciation is not a cash flow, nor is amortization.

The Balance Sheet is a snapshot at a point in time (immediately after closing the books). Two consecutive balance sheets show how assets, liabilities and shareholder equity have changed during the accounting period.
Current: Easier to convert to cash

RONA
RONA = Return on Net Assets, or Net Income/(Fixed Assets + Working Capital)= Net Income/(Fixed Assets + Current Assets Current Liabilities)
RONA is viewed as a measure of how well the enterprise managers are using the enterprise resources. If RONA is low, the managers should liquidate some of the resources and return the money to the owners, who can invest it elsewhere (with a higher RONA).

Why is this important?RONA and EBITDA are typical of the financial metrics ultimately used to judge enterprise performance
Its a good idea to have alignment between operational performance metrics and the metrics that drive enterprise level decisions
In practice, you will need to be able to explain how a particular operational metric relates to the enterprise level financial metrics

Operational KPI Resource focused
Tell something about how resources are used or the condition of resources
Flow focused Tell something about the flow, e.g., its properties or flow results compared to expectations
System focused Combine information about resources and information about flow An important category is productivity measures, which are always of the form,
productivity = (units of output)/(unit of resource) Issue: there are several categories of resource (labor, machines, space, etc) so which productivity metric is the right one? No single productivity metric is adequate by itself
-
ISyE 3104 Fall 2014 Georgia Tech, 2014 12
Resource focused KPI
Provides information about the condition or use of resources, which include facilities (space), equipment, and people.
Examples:
Doctors: clinic hours per day (daily, average)Patient rooms: percent of time occupiedX-ray machines: # exposures since last maintenance;
exposures per day (daily, average)Waiting room: number of patients (at specific times, daily
maximum, daily average, )
-
ISyE 3104 Fall 2014 Georgia Tech, 2014 13
Warehouse resource focused KPI
Examples:
A-frame: fraction of slots utilized (daily, average, max, ); mispicks (per hour, daily, average, )
Flow rack: fraction of facings utilized (daily, average, max); inventory capacity utilization (daily, max, min, average)
Conveyor: % misreads (daily, average, max, min, ); # jams (daily, average, max, min, )
Pickers: paid hours (daily, average, individual, department, ); error rate (daily, average, individual, department, )
-
ISyE 3104 Fall 2014 Georgia Tech, 2014 14
Flow focused KPI
Provides information about flow properties or about flow properties relative to expectations.
Examples:
Number of patients seen per day (by specialty, total, daily, average, )
Patient arrival rate (by specialty, total, by hour, average, max, min, )
Distribution of waiting time (by step in process flow, by specialty, average, max, min, )
% of patients with total flow time less than 60 minutes (by specialty, average, )
NB: Customers dont care about your resource focused KPI, but they certainly do care about flow focused KPI!

ISyE 3104 Fall 2014 Georgia Tech, 2014 15
Warehouse flow focused KPI
Examples:
Orders shipped (daily, average, max, min, by customer type, by carrier, )
Lines picked (daily, average, max, min, by department, by product family, )
Items picked (daily, average, max, min, by department, by product family, )
Contain flow rate from A-frame to fast pick (by hour, hourly average, daily average, max, min, )
Order fill rate (daily, average, max, min, by department, )% orders shipped same day% orders shipped within 24 hours
-
ISyE 3104 Fall 2014 Georgia Tech, 2014 16
System focused KPI
Combines information about resources and about flows. Examples:
Number of patients seen per doctor per day (by specialty, total, daily, average, )
Patient arrival rate (by doctor, total, by hour, average, max, min, )
Exposures per x-ray machine (daily, average, max, min, )Number of patients see per mid-level per day (daily,
average, max, min, )
-

Warehouse system focused KPI
Examples:
Orders shipped per labor hour (daily, average, max, min, by customer type, by carrier, )
Lines picked per labor hour (daily, average, max, min, by department, by product family, )
Items picked per labor hour (daily, average, max, min, by department, by product family, )
(Earned hours)/(paid hours) (Error rate)/((Earned hours)/(paid hours))(Order fill rate)/(average inventory level)

KPIs are an important tool, but They can distort behavior (people respond to rewards and punishments)
No one KPI can give the whole story Beware of sub-optimizing, i.e., focusing on one particular productivity can lead to unanticipated
(negative) outcomes (optimizing the A-frame overloads the slow pick conveyor, resulting in a backup that stalls the A-frame)
There can be conflicting goals, and these result in dueling KPI

Conflicting Operational KPIs in our manufacturing exampleProcurement wants:
Flexible and little variation in delivery time Little variation in mix Large order quantities
Production/Assembly wants: No setups High throughput (productivity)
Warehousing wants: Low inventory Quick picking and replenishment capability
Sales and Marketing want: Large inventory in stock High product variety
What does the consumer want?
