COPLIMO Product Line Investment Model

Background

The Constructive Product Line Investment Model (COPLIMO) helps one estimate the costs and return-on-investment (ROI) of developing system and software product lines. Initially it was oriented for software product line development [1]. It has subsequently been expanded into a general framework for system product lines consisting of software, hardware or combined elements. Cost model portions can be adapted for different product types, processes, and estimation relationships.

Tools

These are web-based tools for different COPLIMO versions.

• Software COPLIMO
• System COPLIMO
• Product Line Flexibility Value Model This tool was created for the DoD Systems Engineering Research Center (SERC) Research Topic Valuing Flexibility in Design (RT-18) [4].

These spreadsheets were developed at the USC Center for Systems and Software Engineering.

• BasicCOPLIMO.xls Basic COPLIMO uses an average software productivity for project effort. See the Basic COPLIMO User Manual.
  
• COPLIMO_full.xls This version implements the full COCOMO II software development model for project effort. Here is the Full COPLIMO User Manual.
• QCOPLIMO.xls A quality extension to COPLIMO for estimating software defect levels.
