How Does IFPUG SNAP Improve Software Development?
IFPUG SNAP or the Software Non-Function Assessment Process is a measurement technique for assessing the non-functional requirements of an application. This particular model contains four categories and a total of fourteen sub-categories used to derive the measurement. IFPUG SNAP uses a set of basic criteria to size a non-functional requirement based on the size and complexity of sub-categories. Organizations using IFPUG Snap sizing are able to enhance the evaluation, management, production control, and planning areas of software development.
IFPUG SNAP Points Are Based On Defined Criteria
IFPUG SNAP consists of four main categories for evaluating size: data operations, interface design, technical environment, and architecture. The categories are then divided into sized sub-categories for determining the total size of non-functional requirements. Examples of these sub-categories include:
- Data Entry Validations
- Data Formatting
- User Interfaces
- Multiple Input/output Methods
- Multiple Platforms
- Batch Processes
- Component Based Software
The categories and sub-categories are used to generate a score based on IFPUG SNAP points, which is similar to the number of functional components counted by function point analysis. The two scores are frequently not equal during software evaluation because each consists of separate components with different qualities.
What Advantages Do Businesses Gain From Using IFPUG SNAP?
An organization gains numerous benefits by incorporating IFPUG SNAP points into software assessment. First, the ability to measure non-functional requirements offers an improved view for estimating development effort. This, in turn, leads to better estimates in these areas:
- Resource Allocation
- Technical Debt
Rather than only evaluating the number of functions completed within code, the addition of IFPUG SNAP makes it possible to evaluate this same factor based on every item contributing to the amount of applied effort. Another benefit organizations receive is the ability to determine delivered end user value based on both functional and non-functional requirements. IFPUG SNAP points are also advantageous for analyzing maintenance projects that do not have any functional user requirements.
Automating Function Point Counting
CAST Application Intelligence Platform (AIP) uses a combination of analysis methods to derive function point counts of applications that comply to IFPUG standards. AIP is an enterprise-driven solution for consistently monitoring several development aspects regardless of the current project phase. CAST offers a function point analysis solution to help with these typical organizational struggles. Our Application Intelligence Platform (AIP) is an option for assessing internally or externally developed applications and finding beneficial areas of improvement within your infrastructure.
