Elise works for a mid$-$size consulting firm. The president of the company is enthusiastic about upgrading its basic information technology systems to share information within the company more efficiently, but is unsure what steps to take. The finance department sometimes produces slightly different figures than the project managers report, and the HR team often walls off its data from other departments. Elise has been asked to propose some solutions to help. Which of the following suggestions would best use technology to create business value?

Provide best$-$in$-$class software specific to each department to improve the data analysis capabilities of each individual department.

Implement a software system that integrates various departments in the firm so that everyone works from the same set of data.

Require employees from different departments to cross$-$check their data with another department before inputting the data to the computer system to reduce error.

Create a proprietary software package that handles HR tasks like hiring and compensation without the need to share data with other departments.
