Overview of product line development

Use cases

With Next Design, according to the product line development use case, you can:

Use case	What Next Design can do
feature model definition	Product variability can be defined in the feature model in tree diagram format.
Product configuration	By defining multiple products and selecting valid features, you can determine per-product variability.
Assigning Features to Design Models	By assigning features to design models, you can identify design model variation points for features.
Confirmation of product applied design model	You can confirm the design model to which the product configuration is applied.
Exporting design models for product application	Design models after product application can be extracted as a separate project.

Definition of terms

Term	Description
Feature	Focusing on the commonalities between products, elements that represent the factors of different ranges (variability) among those products Example: Differences in physical elements of products, differences in hardware, etc. can be features
Feature Model	A model that systematically expresses constraint relationships between features
Product	About the product
Configuration	Definition information for extracting the required product from a group of similar product-intensive systems In many cases, the configuration content for the product is determined by selecting features
Feature allocation	The process of associating variable factors (features) with the range (variable points) in which product-by-product differences occur in similar product-intensive system groups
Product application	The process of determining differences based on the selection of variable factors (features) determined in the configuration for the range (variable points) where differences occur for each product
Mandatory Feature	A feature that must be selected when the parent feature is selected in the configuration
Optional Feature	A feature that can be optionally selected or not when the parent feature is selected in the configuration
Alternative Feature	In the configuration, when the parent feature is selected, one of the siblings of the alternate feature must be selected
Or Feature	In configuration, if the parent feature is selected, at least one of the sibling disjunction features must be selected
Feature Group	A feature node that represents the concept of grouping multiple features in the feature model hierarchy Can define the selectable range in the configuration
Feature conditional expression	A logical expression that defines the conditions for enabling the combination of variable factors assigned to the range (variable point) where differences occur for each product.
