Use your experience and imagination and describe other criteria that are, or might be used to select off-the-shelf software in the real world. For each new criterion, explain how its use might be functional (i.e., it is useful to use this criterion?), dysfunctional, or both.;Once you have decided to purchase off-the-shelf software rather than write some or all of the software for your new system, how do you decide what to buy? Several criteria need consideration, and special ones may arise with each potential software purchase. For each standard, an explicit comparison should be made between the software package and the process of developing the same application in-house. The most common criteria, highlighted in Figure 2-2, are as follows;Comparison of Six Different SourcesSotware Components;Producers;When to Go to This Type of Organization for Software;Internal Staffing Requirements;IT services firms;When task requires custom support and system can?t be built internally or system needs to be sourced;Internal staff may be needed, depending on application;Packaged software producers;When supported task is generic;Some IS and user staff to define requirements and evaluate packages;Enterprise solutions vendors;For complete systems that cross functional boundaries;Some internal staff necessary but mostly need consultants;Application service providers and/or managed service providers;For instant access to an application, when supported task is generic (ASP only);Few, both ASP and MSP free up staff for other IT work;Open-source software;When supported task is generic but cost is an issue;Some IS and user staff to define requirements and evaluate packages;In-house developers;When resources and staff are available and system must be built from scratch;Internal staff necessary though staff size may vary;?
