Requirement Management Process

IPD-standalone software projects are IPD requirement management methods for independent software development. They manage large-scale software development with high quality and efficiency through structured processes and powerful cross-project collaboration capabilities, including raw requirements, system features, R&D requirements, tasks, and bugs, among which tasks and bugs are activities generated and problems found during requirement implementation, respectively.

Table 1 lists the important operations for IPD-standalone software projects.

**Table 1** Operation description for IPD-standalone software projects
Function	Description	Billing
Raw requirement (RR)	RRs are raw problems or requirements described from the perspective of customers. Customer requirements are a type of RRs, which need to be analyzed and reviewed by the RMT/RAT.	You need to upgrade to the Pro or higher edition. For details, see CodeArts Packages.
Feature tree (FT)	FTs contain feature sets and SFs. Feature set: aggregates and manages SFs. Multi-level relationships can be established for the feature set, and the feature tree version snapshot and snapshot comparison functions are provided. SF: feature that brings benefits. SFs can have different types of sub-requirements in this hierarchy: SF > IR > US.
System feature (SF)	SFs are major capabilities of offering requirements or services to support problems (PBs). Offering requirements: a group of complete, consistent, and series of formal requirements planned by product managers/planning representatives. In principle, SFs are a set of key selling points (highlights) of an offering. Each SF is an E2E solution that meets customers' specific business value requirements. Some SFs can be sold separately via license control. PBs: challenges and opportunities faced by customers (customer strategies and pain points), that is, key problems solved by a product or service for customers. Resolving key problems can bring core value to customers.
R&D requirement (IR/US)	There are two work item types under R&D requirements: Initial requirement (IR) IRs are re-described accurately, with complete background, in standard format, and from the perspective of customers/markets. User story (US) User stories are brief description of functions that are valuable to users or customers, which comply with the INVEST principles. USs are decoupled and can be delivered independently, which is the basis of agile sprint delivery.
Task	Tasks are activities with a certain goal.
Bug	Bugs are problems found in a project.
