  • The Incremental Commitment Model & Rapid-fielding projects
  • Process Pattern Decision Driver
  • Preliminary Results

motivation
Motivation
  • Growing diversity of software systems
    • No one-size-fits-all process for the full range of software systems
  • Rapid Fielding is a very important Software System Objective
    • To fit into market windows, respond to competition
    • Several possible process patterns can be used
  • Some process models provide specific evidence-based and risk based decision points
    • ICM is the most thoroughly elaborated

NDI/NCS Growth Trends

*

USC e-services project data shows increase in number of projects using COTS from 28% in ‘97 to 70% in ’02 - Similar results (54% in 2000) were found in the Standish Group’s 2000 survey [Yang 2006].

USC e-services project data shows increase in number of projects using NCS from 19% in 2006 to 57% in 2009

Architected Agile

E.g. Business data processing

Use Single NDI

E.g. Accounting System

NDI-Intensive

E.g. Supply Chain Management

definitions of ndi ncs
Definitions of NDI / NCS
  • NDI or Non-developmental Item is an item that is previously developed and available to use. It includes commercial-off-the shelf, open source product, reuse library and customer-furnished package.
    • Two main categories of NDI are
      • platform-based NDI such as Internet Explorer, Eclipse, MySQL, Apache Tomcat, JDK/JSP
      • application-based NDI such as Microsoft office, Quickbook, BusinessWorks, Barcode Generator, JMP and primopdf.
  • NCS or Net-Centric Services is an online service available to be accessed over the Internet such as Google services, Yahoo services, Google map, Twitter, Ning.com, Gmail, Facebook, Amazon payment, online currency converter and online dictionary.
    • Net-Centric Services is known as web service, web application, online application, cloud computing, and software-as-a-service.

Process Pattern Decision Driver

Note: Decision importance scale varies from project to project

Decision Criteria Rating Scale; 0:Very Low; 1:Low; 2: Medium; 3:High; 4:Very High

Importance Rating Scale: 1:Low; 2: Medium; 3:High

The Incremental Commitment Model – Electronic Process Guide (ICM EPG)

Using IBM Rational Method Composer to build a software development process guideline mainly describing roles, responsibilities and artifacts.

preliminary results
Preliminary Results
  • 28% of projects are able to deliver in one semester, instead of two semesters comparing to 12.5% from previous year
  • Clients are highly satisfied with the project results
  • Less effort spent in project development

USC CSSE ARR 2010

conclusion
Conclusion
  • For rapid-fielding software projects, this research focuses on developing and evaluating the effectiveness of process guidelines for 4 process patterns.
  • The approach is being used to validate and refine the content of the process patterns
