This case covers an important decision of a type that confronts many managers. Several years ago TDG Engineering upgraded its IT network infrastructure, and now experienced and trusted employees are recommending yet another upgrade. The question at hand is whether this upgrade is justified, and how long the new capabilities will last before another request for yet another upgrade. In addition to addressing issues about the importance of infrastructure and the justification of IT investments, this case provides an example that illustrates concepts related to system life cycles, the alignment between business strategy and IT strategy, and the uncertainties related to whether IT investments will be successful.
