What's change control?
Change control is a systematic approach to managing all changes made to a product or system. The purpose is to ensure that no pointless modifications are made, all changes are documented, companies aren't unnecessarily disrupted and resources are used efficiently. Within information technology (IT), change management is a component of change management.
The change control process is normally conducted as a sequence of steps proceeding from the submission of a change request. Typical IT change requests embody the addition of options to software applications, the installation of patches and upgrades to network equipment or systems.
What's the process of change management?
Here's an instance of a six-step process for a software change request:
Documenting the change request. The client's change request or proposal is categorized and recorded alongside with informal assessments of the significance of that change and the problem of implementing it.
Formal assessment. This step evaluates the justification for the change and the risks and benefits of making or not making the change. If the change request is accepted, a development workforce will be assigned. If the change request is rejected, that is documented and communicated to the client.
Planning. The workforce responsible for the change creates an in depth plan for its design and implementation, as well as for rolling back the change ought to it be deemed unsuccessful.
Designing and testing. The crew designs the program for the software change and tests it. If the change is deemed successful, the staff requests approval and an implementation date.
Implementation and review. The workforce implements the program and stakeholders review the change.
Final assessment. If the consumer is happy with the implementation of the change, the change request is closed. If the consumer just isn't happy, the project is reassessed and steps could also be repeated.
Change control in project management
Change management is a vital part of project management in IT and non-IT areas -- including manufacturing and prescribed drugs -- and generally is a formal or casual process. Project managers study change requests to determine their potential impact on the project or system as a whole. Efficient change control processes are critical for incorporating obligatory modifications, while guaranteeing they do not disrupt other project activities or delay progress. Every potential change must be evaluated in relation to its potential impact on the following:
scope of the project;
schedule of progress and milestones;
prices of additional labor and other resource requirements;
quality of the completed project, as extreme quantities of work can lead to rushed work, leading to a higher likelihood of defects;
human resources, as change requests might require additional labor or specialised skills;
risk, as even minor modifications can have a domino effect on the project leading to potential logistical, monetary or security risks;
procurement of materials, labor, skills and other vital project resources; and
stakeholders -- together with project managers, executives, firm owners, group members or traders -- who could voice their support or push back on a project.
Benefits of change management
Efficient change management can provide the next potential benefits for projects in any industry:
higher cost and risk avoidance;
lower risk related with every particular person change;
reduced amount of time needed for changes;
changes could be factored in with less disruption to project schedule, as requests will be considered and managed around the project timeline; and
project managers will learn about change wants within the planning part and have time to consider doable courses of action.
