CS302 2021 A.01: Software Configuration Management Saylor Academy

The airlift ended in September 1949 after the Soviet Union ended their blockade. The CM plan may be a standalone document or it may be combined with other program/project planning documents. It should describe the criteria for each technical baseline creation, technical approvals, and audits. The build process and products are often subject to software quality verification. Outputs of the build process might be needed for future reference and may become quality assurance records. Software configuration status accounting (SCSA) is the recording and reporting of information needed for effective management of the software configuration.

One of the key inputs to preparing for CM implementation is a strategic plan for the project’s complete CM process. This problem is ready to be solved by the off- shelf software (Gahinet et al. 1995). The MATLAB function, hinfmix in the LMI toolbox, originally designed for mixed H2/H∞ problem has been slightly modified for the generalised-H2/H∞ problem in (2).

Multiobjective Process Controllability and LMI

Signals, which link both blocks, are measured output, y and manipulated input, u. The signal w represents exogenous inputs, such as disturbances, references, noises and inputs from uncertainties and the exogenous output, z, is the control objective. Many control performance specifications can be expressed as the H∞ norm of certain closed-loop transfer functions. Such functions could be the sensitivity function, S, complementary sensitivity function, T, the input sensitivity function, KS, or more generally, a closed-loop transfer function from w to z, i.e. ||Tzw||∞.

He’s currently focused on the emerging DevOps culture and the tools for enabling better continuous integration, continuous delivery, and data analysis. During his career, he’s successfully managed enterprise software development tools in all phases of their lifecycle. He has driven organization-wide process improvement with results of greater productivity, higher quality, and improved customer satisfaction.

Jira Product Discovery

From this point forward, only change requests or proposals that have been approved by the software change control board (CCB) should be integrated into the structural configuration. For example, configuration requirements may be different for a network firewall that functions as part of an organization’s Internet boundary versus one that functions as an internal local network firewall. Configuration change management is a process to manage approved designs and the implementation of approved changes. Configuration change management is achieved through the systematic proposal, justification, and evaluation of proposed changes followed by incorporation of approved changes and verification of implementation. Implementing configuration change management in a given program/project requires unique knowledge of the program/project objectives and requirements. The first step establishes a robust and well-disciplined internal NASA Configuration Control Board (CCB) system, which is chaired by someone with program/project change authority.

In 1970, a new hangar was inaugurated; this accommodated six jet aircraft and was the world’s largest hangar at the time. Keeping track of the state of the board and other system variables can be just as important as knowing what version of the FPGA was loaded at the time of a specific fault or failure. In other words, when a problem occurred did it have the latest group of hardware modifications? The answers to these questions can help identify system problem sources.

Version Control

The following list of other configuration management tools is designed to be stored in a Git repository and leverage Git version control tracking. Software configuration management is a systems engineering process that tracks and monitors changes to a software systems configuration metadata. In software development, configuration management is commonly used alongside version control and CI/CD infrastructure. This post focuses on its modern application and use in agile CI/CD software environments. Configuration management is a systems engineering process for establishing consistency of a product’s attributes throughout its life.

SCM is a supporting software life cycle process that helps
development and maintenance activities, assurance activities, and project management in general. The functional architecture should be placed under technical configuration control to establish a functional design baseline ccb definition for software design synthesis. The functional architecture must be complete and traceable to software specifications. The software configuration management (SCM) process is looked upon by practitioners as the best solution to handling changes in software projects.

Configuration Documentation Classification Guide

By careful FPGA design configuration management and part programming and tracking, serious problems can be avoided. With the freedom to change, recompile and reload the FPGA design to a board comes the responsibility to keep track of changes and keep FPGA design versions under configuration control. It is not enough to always have access to the latest design FPGA version. Occasionally it may be necessary to go back ten or more versions of the FPGA design to revisit a specific problem or subsequent fix.

This reverse engineering process is wasteful in terms of human and other resources and can be minimized or eliminated using CM. Configuration management is a necessary tool for managing complex software systems. Lack of configuration management can cause serious problems with reliability, uptime, and the ability to scale a system. Many current software development tools have configuration management features built in. Bitbucket offers a powerful system for configuration management that is built around Git pull request workflows and CI/CD pipelines. CI/CD configuration management utilizes pull request-based code review workflows to automate deployment of code changes to a live software system.

Software Configuration Auditing

The protests even continued after the runway had been opened in 1984 and in 1987 two police officers were killed by a gunman. Because of its orientation in the north–south direction, in contrast to the other east–west runways, the use of the third runway is limited. The Startbahn West can only be used for takeoffs to the south to avoid interference with air traffic on the other runways. Owing to this restriction the runway must be partially or fully closed when northward winds are too strong. The new terminal, called Terminal Mitte (Central Terminal, today known as Terminal 1) is divided into three concourses (A, B and C) with 56 gates and an electric baggage handling system.

The purpose of the software physical configuration audit (PCA) is to ensure that the design and reference documentation is consistent with the as-built software product. Change management is an ITSM process that is related to—but distinct from—configuration management. It describes the policies and processes your organization follows when updating infrastructure or responding to critical events such as service performance degradation or outages. Complex assets such as aircraft, ships, industrial machinery etc. depend on many different components being serviceable. This serviceability is often defined in terms of the amount of usage the component has had since it was new, since fitted, since repaired, the amount of use it has had over its life and several other limiting factors.

5 Establish the functional architecture

This baseline is usually created by reviewing the configuration of a functioning production environment and committing those configuration settings. Gateway Gardens is a former housing area for the US Air Force personnel based at the Rhein-Main Air Base, close to Terminal 2. Since then the area is being developed into a business location for airport-related companies. Lufthansa moved its airline catering subsidiary LSG Sky Chefs to Gateway Gardens, Condor and SunExpress are headquartered here.
