Input Artifacts:

Input Artifacts are the artifacts collected from the products variants used in the re-engineering process.

Source Code

Code that implements the software products being re-engineered.

Requirements

Requirements of the software products used. Requirements can be described using different ways. Most common types used during the re-engineering process are:

Requirements List

A list containing functional and non functional requirements of the system. They can be ordered by priority, cost or preference by the stakeholder.

Use Cases

Use cases are represented in form of a diagram and a text description. Each use case represents a functionality of a system been performed by someone in a determined context.

Business Rules

Business rules are related to company or organizational rules that must be followed by the system.

Design Models

Models designed during the project of the products used in the re-engineering process. The most used models during this process are:

Class Diagram

Class diagrams of the products that may include project patters, architectural patters and other project information.

State Machines Diagrams

Represent possibles states that a system can take.

Feature Models

It is possible to use a feature model as an input artifact of the re-engineering process, although they are also an output. The feature model describes the features of a family of systems, and can be modeled in different notations.

Activity diagrams

They are graphical representations of workflows of activities and actions. Can be used to describe use cases, or even algorithms.

Domain Information

Artifacts created during the domain engineering, focusing on the development of reusable assets.

Reference Architecture

It is the product line architecture. Describes, in general, a solution for the range of products in the product line.

Reference Requirements

They are the requirements created for the reference architecture and its implementation.

Output Artifacts:

Output artifacts are the artifacts generated during the process execution. They can also be used as input.

Feature Artifacts

Feature Artifacts are generated from the application of the feature retrieval techniques. Each technique can generated different artifacts such as graphs representation of features or feature descriptions.

Reports

Reports written in natural language containing information such as the variability among the systems. Download a Feature report template here. The template for Feature Retrieval Techniques Report, where the decisions of choosing or not a technique are documented can be downloaded here.

Modified Product Artifacts

Product artifacts modified to include feature entry points. These entry points are the location where the feature was discovered in the artifacts. They may be source code comments, use case annotations, etc.

Team information Report

report(s) containing information such as team experience, team skills and team knowledge. This document should contain the information of all team members. Download Template

Domain Artifacts

Products description, user comments, documentation of systems in specific domain, and domain analysis.

Domain Glossary

Contains names, terms, synonyms and any kind of terminology specific for the system domain.

Domain Constraints List

List of constraints related to the system domain. This constraints can be collected in the system business rules or even non-functional requirements.

Requirements Specification

Requirement information collected and registered during the execution of this process. Requirements artifacts may be Requirements List, Use Cases, User Stories or any kind of requirements specification.

Artifacts Type Specification

Information about artifacts types such as extensions, formats and templates used. Download Template

Development Information

Design patterns, architectural patterns, programming patterns, programming and development paradigms and even technological information can be included.

Process Execution Report

Document containing the experience about the process execution. Main decisions and difficulties may be registered as well. Download Template.
