How is the concept of core competency relevant to Smalltown computer, a local computer repair store that builds custom computers? Give examples. LONG ANSWER
A core competency is an activity for which a company is a world leader, and from this perspective, Smalltown Computer does not have a core competency, as there are thousands of similar firms with longer track records.

In defining a core competency, the business management can then determine ways to enable employees to understand and reach higher levels of quality production and service. For example, Smalltown Computer might define a core competency as being able to advise customers as to the types of system they really need, and Smalltown Computer could engage in knowledge gathering activities to help employees assess customer need.

You are starting a market research company with a single business partner and are planning the hardware and software need for the two of you. Which factors should play into your decision of how much to spend on these investments? LONG ANSWER
Using the competitive forces model for IT infrastructure investment, the most relevant factors in this decision are: ● The firm's business strategy. What capabilities will we want to have over the next five years? ● Alignment of IT strategy. How does our IT strategy match up with the business plan? ● IT assessment. What are the current technology levels for the services we are offering and our business type? We would probably not need to be at the bleeding edge, but not behind the times either. ● Competitor firm services. What technology-enabled capabilities do our competitors have? We would want to match services with our competitors. ● Competitor firm IT investments. How much are competitor firms investing in their technology? Because this is a startup, one other factor may not play such a large role: that of market demand for services. However, finding out the market demand for competitor's services may uncover ways that this new company could have a competitive advantage.
