Configuration Control an overview
A structured and consistent process for CCB meetings and reviews can help streamline the workflow and reduce the risk of errors and inconsistencies. By following such a process, changes can be managed in a timely, transparent, and traceable manner. Figure 6-4 models the third segment of Figure 6-1,
covering the portion of the process concerned with Government review
and disposition of contractor submitted ECPs and RFDs. It illustrates
local Government representative review and concurrence with class
II changes and minor deviations (where such action is contractually
required) and its endorsement (or non-endorsement) of class I changes
and major/critical deviations. The CCB then
reviews the proposal and the implementation commitments and either
approves or disapproves them in accordance with the procuring activity’s
policy. As a result of the CCB decision, implementing direction
is given, typically in the form of a CCB directive.
The CDCA is the organization
that has the decision authority over the contents of the document,
reflecting proprietary or data rights to the information that the
document contains. The CDCA may be a Government activity or a contractor,
and the authority may be transferred. Package includes hundreds of multiple-choice practice test questions, performance-based questions, audio, and flashcards.
Systems Development Executives and Managers
When a decision is rendered,
the CCB chairperson approves a CCB directive, or equivalent letter/memorandum,
directing the appropriate implementing actions to be completed. The last best practice for conducting effective CCB meetings and reviews is to evaluate and improve the CCB performance. This includes measuring and monitoring how well the CCB meets its goals, objectives, and expectations, https://www.globalcloudteam.com/ as well as identifying and implementing actions to enhance the CCB processes, practices, and outcomes. Evaluating and improving the CCB performance can help you ensure that it meets its purpose and adds value to the CM process. The Change Control Board and Change Advisory Board share a similar focus of reviewing and making decisions for change requests, though their scopes vary widely.
Since all existing CI configurations cannot often be updated simultaneously,
careful consideration must be given to either delaying or accelerating
the incorporation of the change to minimize the impact. Setting
effectivity to a future defined block of the CIs may be one solution. Combining or packaging a number of software changes into the next
version may be another, etc. This responsibility is further complicated when multiple versions of the target hardware exist, which require different versions of the FPGA design. For example, if a board update to a hardware design requires swapping an input and output between two FPGA pins, the FPGA versions for the modified board will have to be different than those loaded onto the unmodified board.
Developing a Configuration Management Plan
The organization employs automated mechanisms to implement changes to the current information system baseline and deploys the updated baseline across the installed base. Once the FPGA design has been captured and compiled and initially downloaded to the HW target, configuration tracking needs to be maintained at the board level in the lab. Efficient real-world debugging is much easier when as many variables as possible are removed when trying to determine the source of a problem.
Loading the wrong FPGA version to a board could result in unpredictable behavior or component damage. By careful FPGA design configuration management and part programming and tracking, serious problems can be avoided. (Contractors also employ a similar process for their internal configuration
control.) CCBs are usually comprised of the joint command or agency
body chartered configuration control boards to act on class I ECPs and requests for major or
critical deviations. The program manager is normally the chairperson
of the CCB and makes the decisions concerning all changes brought
before the CCB. The CCB is a program management process used by
the program manager to ascertain all the benefits and the impacts
of the change before the decision is made.
Who are the project people involved in the configuration control board CCB?
Figure 6-1 illustrates
a top-level activity model of the configuration control process. It shows the configuration control process divided into three segments,
which are detailed in Figures 6-2, 6-3 and 6-4, respectively. Another key to successful CCB meetings and reviews is to prepare the change requests and supporting documents in advance. A change request is a formal document that describes the proposed change, its rationale, its impact, its priority, and its dependencies. Supporting documents may include technical specifications, design drawings, test results, risk assessments, cost estimates, and customer feedback. Preparing these documents ahead of time ensures that the CCB has all the information it needs to evaluate the change request and make an informed decision.
by the CCB include both contractual actions and tasking orders for
Government activities, as applicable. In response to a CCB Directive,
the Government contracting office prepares and negotiates a contract
modification to authorize the contractor to proceed with implementation
of the approved class I ECP or major/critical deviation. A Change Control Board (CCB), also known as the configuration control board, is a group of individuals, mostly found in software-related projects. The group is responsible for recommending or making decisions on requested changes to baselined work.
Change Control Board vs Change Advisory Board: What’s the Difference?
Online platforms are another beneficial tool which allow CCB members to conduct meetings and reviews remotely with video conferencing, screen sharing, chat, and file sharing features. Additionally, decision-making techniques can help analyze, compare, and choose among different options for change requests. These techniques include criteria-based evaluation, multi-voting, and consensus – each requiring active participation from CCB members. In conclusion, using the right tools and techniques can significantly improve the quality, speed, and accuracy of CCB decisions. In performance based acquisition, the definition of both class
I and class II changes have been modified to reflect application
only to changes that impact Government approved (baselined) configuration
- 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).
- Joseph is a global best practice trainer and consultant with over 14 years corporate experience.
- The functional architecture must be documented to provide the diagrams, drawings, models, and specifications against which software design synthesis can be performed and evaluated.
- Pass the first time with quality practice test questions, performance-based questions, flashcards, and audio.
- A structured and consistent process for CCB meetings and reviews can help streamline the workflow and reduce the risk of errors and inconsistencies.
- The contractor makes the decision when the change is to items/configuration
documentation for which it is the configuration control authority,
provided those changes do not impact the Government’s baselines.
Functional architecture includes the design documentation shown in Table 11.1. Table 6-1 provides an activity guide for the evaluation of a
configuration control process. CCB charters are normally approved through the government procuring
activity official administrative channels. All CCB members must
be present at each CCB meeting and should be familiar, from their
functional perspective, with the changes being considered.
The Configuration Control Board’s Role in Change Management
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 can only be accomplished if versions of the FPGA design are well documented and carefully stored away for future retrieval. Use this template to create your board charter for your configuration control board (CCB).
This is achieved by increasing the dissolved oxygen in Z2 and decreasing it in zone Z3 and zone Z4. The DMC controlled variables are the ammonia concentration in Z5 and the nitrate concentration in Z2. The different DMC configurations obtained with different choice of the manipulated inputs are reported in Table 1. For each configuration the set-points of Z2-SNO and Z2-SNH were both set equal to 1 mgN/L, p was set equal to 10 and q equal to 4. The results in terms of pollutant removal and energy consumption are reported in Table 2, where they are compared with the results obtained with the control default configuration of BSM1. All applications of the affected CI must be considered when classifying
a change, e.g., ECPs initiated against a CI being manufactured by
more than one contractor, a CI which has multiple applications or
is used by more than one tasking (application) activities.
CM-3 CONFIGURATION CHANGE CONTROL
Using appropriate tools and techniques can significantly increase the effectiveness and efficiency of CCB meetings and reviews. CM software, for example, automates and simplifies the CM tasks, such as creating, storing, tracking, and reporting change requests and CIs. It also enables collaboration between CCB members and other stakeholders, as well as providing audit trails and security features.
