Document Summary

Four basic methods for acquiring software applications: buy it and use it, buy it and customize it (most common, rent or lease it, build it yourself. Acquiring new software is not the same as acquiring now information systems because there is a lot more to think about in systems than jut software. Components: scope (objective, start and end date, temporary use or resources, unique, accomplish something new (change) In terms of budget or personnel: new email application, crm or erp installation. Require fundamental change to business process: new it supports the changes. Chaos report (1994: 16% delivered on time, budget and scope, 30% cancelled before delivering anything. Sauer, gemino and reich report: 66% success rate (2 out of 3, 25% general failure independent of size. Difficult to: estimate time, budget, scope. Risks to consider: lack of experience, lack of support, lack of participation, unclear project requirements, technical complexity. Project on time/on budget: product performance. Pathways through model: forces of evil/good.
