The first stages of a cloud project should begin with understanding the business use cases and product strategy. This information sets the context for later work on the technical requirements analysis.

One part of business requirements analysis includes application design and cost considerations. Application design considerations include assessing the possible use of managed services and lower classes of service that cost less than standard services. Data lifecycle management is also a factor in application design.

In addition to business drivers, consider regulations that may apply to your projects. Many regulations are designed to protect individuals' privacy or to ensure the integrity of data to prevent fraud. Compliance with regulations may require additional security controls or application features that otherwise would not be implemented.

Security business requirements can be framed around three objectives: protecting confidentiality, preserving the integrity of data, and ensuring the availability of services, especially with respect to malicious acts that could disrupt services. There may be ancillary security requirements as well. For example, if a company sends a digital purchase order, the recipient should be expected to send a signed acknowledgment proving that they received it. This kind of nonrepudiation requirement may occur with external business processes.

Business and other organizations will often monitor the progress of projects and the efficiency and profitability of lines of business using success measures, such as KPIs and ROI.
