Q1) Identify the most common criteria for choosing off-the-shelf software.Which two criteria would be among the most important?
Answer: The most common criteria are cost,functionality,vendor support,vendor viability,flexibility,documentation,response time,and ease of installation.Cost involves comparing the cost of developing the same system in-house to the cost of purchasing or licensing the software package.Functionality refers to the tasks the software can perform and the mandatory,essential,and desired system features.While vendor support identifies the amount of support the vendor can be expected to provide,vendor viability examines the vendor's marketplace strength.Flexibility refers to the flexibility of customizing the software.The documentation criterion examines issues relating to the user's manual,technical documentation,and cost of acquiring additional copies of the documentation.Response time questions the length of time it takes the software package to respond to the user's requests in an interactive session and how long it takes the software to complete running a job.The ease of installation criterion examines the difficulty of loading the software and making it operational.Vendor support and viability will be among the most important.
