1. Begins with mission statement
2. Customer benefit package
•
•
•
•
•
Identify company
Define your product (cannot be a service)
Identify your market space, your market niche
Forecast production requirements (demand)
Discuss production capacity strategy
Part 1, #1 – Mission Statement
•
•
•
•
Part of your business plan
What type of business or class of products?
Who your customers will be (demographics)
Future path of the organization (values)

Day and ask instructor to clear up any questions
Part 1, #2: Customer Benefit Package
CBP
• Concept development
– Where did your idea came from(investors want to know)
• Detailed description of the product (diagrams, pictures,
etc.)
• Define CBP –attach CBP diagram
• Break-even timeline (details later)—how long does it
take to get to breakeven– initially costs exceed
revenues, but over time accumulated revenues catch
up and eventually exceed accumulated costs—say in 18
to 24 months, hopefully
#3 Strategy Development
• Environmental scanning – market niche
• Customer and market requirements for your
product

– Features that are Order winners – like kicking your
foot under the tailgate of the Ford Escape

#5 – Product Design
• Preliminary design and testing – stages
• Final Design – raw materials and equipment
required to manufacture
#6 -- Forecasting
• We always forecast demand—so we can plan to
have enough capacity to accommodate demand
• Past 5 years data from this company
• Attach linear regression formula and graph
• Attach table of next 5 years forecast for company
selected
• Pick and defend a % of their forecasted sales for
your 1st 5 years sales
• Attach table of your 5 year forecast

#7 cont. Checking Forecasts
• Select POTENTIAL (example only – hasn’t
happened yet) sales for next 5 years
• Attach (Include) Calculation of MAD and
Tracking Signal
• Explain meaning of results
• Discuss relevancy of seasonality
– Think “Seadoo” and “Skidoo”
• Attach 1st year as a seasonal forecast if
appropriate
Mean Absolute Deviation (MAD)
 Dt - Ft 
MAD =
n
where
t = period number
Dt = demand in period t
Ft = forecast for period t
n = total number of periods
 = absolute value

# 8 - Break Even Analysis
• Describe breakeven analysis
• Attach (include) fixed cost (annualized for 5
years), variable costs, and sales price per unit
• Attach (include) breakeven analysis
calculated in units
• Attach (include) breakeven timeline based on
your forecast
Process Selection With
Break-Even Analysis
Total cost = fixed cost + total variable cost
TC = cf + vcv
Total revenue = volume x price
TR = vp
Profit = total revenue - total cost
Z = TR – TC = vp - (cf + vcv)
cf = fixed cost
V = volume (i.e., number of units produced and sold)
cv = variable cost per unit
p = price per unit

Process Selection With
Break-Even Analysis

Break-Even Analysis
Fixed cost = cf = $2,000
Variable cost = cv = $50 per unit
Price = p = $100 per unit
