ANALYZE: Unit Sales
This screen tracks the unit sales for both battery types, color coded by market
segment.
On this screen, like most others in the simulation, click View Data to see the data
presented in tables.

ANALYZE: Desired Features
The 2 battery types vary in performance across 5 technology features:
1. Energy density – a measure of
how long a battery lasts
2. Recharge cycles – how many
times the battery can be
recharged before it is no longer
able to hold a charge
3. Self-discharge to 50% – how
quickly a fully charged battery
loses its charge when it is left
unused
4. Recharge time – the minutes to
fully recharge the battery
You can monitor how both battery types perform across the feature categories
compared to customer desired feature performance. Toggle between the different
market segments to view how preferences vary by customer type.

ANALYZE: Feature Performance
You can monitor your R&D investment and feature performance for each battery type
across each of the 5 categories.
If you want to see substantial performance improvements, you have to invest in your
own R&D.

ANALYZE: Potential Customers
The potential customers for all three markets is large. The portion of potential users
and installed base vary from market to market and from year to year.

ANALYZE: Income Statement
The Income Statement provides a summary of yearly net income with two years’
historical data.
Cumulative Profit is the yearly net income accumulated through the course of the simulation.

ANALYZE: Dashboard Overview
(Advanced Scenario)
Your sales variance determines how successful you were at setting your sales forecast.
If your variance is too great, you'll get fired. There are three ways that you can get
fired:
1.
2.
3.
You have very large negative sale variance in one year.
You have a large negative variance for several years in a row.
You lose money for several years in a row.

ANALYZE: News
Market News is updated annually based on the previous year’s performance.
New market news stories are denoted with
a number in the navigation bar at the
beginning of each round. Clicking on that
number launches that year’s news.
Click “View All News” to
launch the Market News
screen and read all market
news stories for all years.

DECIDE: Decisions
This is where all Decisions are entered. For each battery type,
• Enter the next year’s Sales Forecasts
• Set the Price
• Select R & D Investments for each feature area
You must also
submit a brief
statement
explaining your
strategy. This entry
is mandatory in the
first year, but can
be revised in later
years. Your entries
will be viewable by
your professor.

DECIDE: Additional Screens
After you submit your first year’s decisions, these screens will populate and help you
track and review your decisions as you progress through the simulation:
• R&D Investment Opportunities
• R&D Spending History
• Sales Forecast History
(Advanced Scenario)
• Price History

Archived Runs
Depending on simulation setup
determined by your facilitator,
you may be able to run the
simulation more than once. The
simulation saves each run you
start.
To view or resume your prior
run attempts, click the
“Archived Runs” link at the
bottom of your screen.

Cumulative Profits
Depending on simulation setup
determined by your facilitator,
you may be able to view a list of
your classmates’ cumulative
profits, and possibly, their
corresponding strategies.
To see the Cumulative Profits
list, click the link at the bottom
of the screen.
