Introduction

Over the past decade, a number of the standards development organizations (SDOs) and other industry associations have been working collaboratively to align the systems and software engineering standards. The objective is to have a set of standards that can easily be used concurrently due to their use of common terminology and concepts.

Problem

There has been a lack of integration both within and across SDOs. This has led to Systems and Software engineering standards that have different terminology, process sets, process structures, levels of prescription, and audiences. These differences have been both between Systems and Software, and to some extent within each. The problem has been exacerbated by competing standards, in whole or part. (Roedler 2010)

Cause

The cause of this problem includes several factors, as follows:

  • Culture - “We’re different”; “Not invented here”
  • Organizational - Different teams, committees, etc.
  • Competition - Many Standards Development Organizations
  • Domains - Focused, narrow view often doesn’t look beyond the domain for commonality

(Roedler 2010)

Impact

The impact of this problem includes the following:

  • Less effective or efficient processes that are not focused on leveraging commonalities. This causes redundancy and has resulted in incompatibilities, inconsistencies between the standards making it difficult to concurrently use them together.
  • Less effective solutions that are not focused on a common approach to solve a problem or need.
  • Obstacle for communicating (at all levels – disciplines, teams, etc.). working in integrated teams, and leveraging resources.
  • Stove-piping due to the incompatibilities, inconsistencies, and lack of leveraging commonalities.

(Roedler 2010)

Objective

The objective is to make the standards more usable together by achieving:

  • Common vocabulary
  • Single, integrated process set
  • Single process structure
  • Jointly planned level of prescription
  • Suitable across the audiences
  • Accounts for considerations in wide range of domains and applications

(Roedler 2010)

Alignment of Systems Engineering Standards

Approach

A collaborative effort has been in place for the past decade that includes ISO/IEC JTC1/SC7 (Information Technology, Systems and Software Engineering), IEEE Computer Society, the International Council on Systems Engineering (INCOSE), and others. Figure XA depicts the approach being used to align the standards through this collaboration. It is built around a foundational set of vocabulary, process definition conventions, and life cycle management concepts provided by ISO/IEC/IEEE 24765 (Systems and software engineering vocabulary), ISO/IEC TR 24774 (Guidelines for process description), and ISO/IEC/IEEE TR 24748-1 (Guide to life cycle management), respectively. At the heart of the approach is the alignment of the ISO/IEC/IEEE 15288 (System life cycle processes) and ISO/IEC/IEEE 12207 (Software life cycle processes), which provide the top level process framework for life cycle management of systems and software. This enables concurrent and consistent use of the standards to support both systems and software life cycle management on a single project. The approach includes the development or revision of a set of lower level supporting standards and technical reports for elaboration of specific processes, description of practices for specific purposes (e.g., systems/software assurance), description of artifacts, and guidance for the application of the standards,
