decision Making
Assumptions
No matter what kind of decision is being made, the manager will always base his or her
decision on certain assumptions. For example, the manager’s decisions to have his or
her department work overtime on a holiday weekend, will likely rest on the following
certain assumptions:
The output achieved during the overtime is needed and must occur during that
period, which means that it could not be produced at another time without
hurting customer service.
The added overtime premiums incurred will not turn the eventual sale of the
products into unprofitable transactions.
He or she has the option to require mandatory overtime and that he or she will
not have to ask versus require the extra work hours.
If any of these assumptions prove to be untrue, his or her decision to schedule the
overtime may prove to be a bad one.
For the first assumption, if the output to be produced during the overtime will not be
sold for days or weeks after the holiday, then working overtime now may be an
unnecessary added cost and could negatively impact employee relations or morale.
For the second assumption, if the normal labor cost of the product is $5.00 per unit and
the normal profit is $1.00 per unit, will the product still be profitable? If the overtime
labor cost is $7.50, then working overtime to produce these items will result in a loss of
$1.50 per unit.
$2.50 additional labor cost - $1.00 normal profit = $1.50 per unit loss
If the supervisor requires overtime work on a holiday weekend, he or she will most
likely incur some level of negative employee reaction because many employees would
prefer to be with their families during the holiday weekend. If overtime is made
mandatory when the company policy says that it should be voluntary, he or she will
surely cause some negative impact on employee relations or morale.
Whenever managers make important decisions, they should formally or informally
make a list of their key assumptions. In annual strategic or business planning, key
assumptions are a formal requirement of good plans. For example, in a strategic plan,
typical assumptions include the following:
assumptions about current or future likely legislation that could affect the
industry
assumptions about the likely entrance and/or exit of new competitors
assumptions about market trends for the company's products, frequently
dictated by technology development
assumptions about the long-term market growth for a product
If any one of these major assumptions proves to be invalid, the entire strategic plan of
the firm could be at risk.
