Recommended: Importance of software maintenance and change control

Software Maintenance and Change Control In today's world there is very unusual to have a program developed that will not have further development after release. The requirements of the time that we live are very dynamic and there is a need for constant adaptation. A basic requirement for any new software product is to be adaptable, easy to maintain and modify. Time factor and cost factor are ruling in the agitated competition and only those who are well organized and prepared are able to survive. The question for software maintenance and change control is taking key position in both perspectives: the perspective of the manufacturer of the software, and the perspective of the consumer. In the negotiation and management of these two major players is the complexity of the software maintenance and change control. In this paper we will focus on some important specifics of these processes. Thomas Pigoski in his "template for a software maintenance plan" defines software maintenance in the following way: "Software maintenance is the totality of activities required to provide cost-effective support to a software system. Activities are performed during the pre-delivery stage as well as the post-delivery stage. Pre-delivery activities include planning for post-delivery operations, supportability, and logistics determination. Post-delivery activities include software modification, training, and operating a help desk." Later on in the same material he describes some organizational requirements in the same context: "Maintenance is performed by the developer, a separate maintainer, or by a third-party organization. It is important that the organization responsible for maintenance be identified in writing with full responsibilities. The Maintenance Plan accomplishes this.

    Some software systems have a relatively short lifetime (many web-based systems), others have a lifetime of tens of years (large command and control systems). Some systems have to be delivered quickly if they are to be useful. The techniques used to develop short-lifetime, rapid delivery systems (e.g. use of scripting languages, prototyping, etc.) are inappropriate for long-lifetime systems which require techniques that allow for long-term support such as design modelling.

    Software maintenance stands for modifications and updates done to the software after the delivery of software product. There are several different reasons, why software maintenance is required. Software needs to be updated regularly to keep it functional with the new and latest technology. Once software is developed, it does not mean it is the final product or perfect. Software may need to be modified or updated because of errors or new customer wants new features to be added to the software. There are also several other reasons such as market conditions, host modifications and organization changes. (Tutorialspoint 2015)

  • Patch Management

    Windows Server 2012 is a dynamic piece of software as it is constantly evolving. These improvements are available to users in the form of Windows Updates and patches. The results of an audit can show that without proper monitoring our system can slowly become obsolete, less productive, and potentially out of Government compliance. Microsoft is constantly making improvements or fixing bugs through a series of updates. Some of the updates are very important to keep products like Windows Server 2012 up to date and secure. Other updates may be labeled as recommended or optional from Microsoft. “Microsoft routinely releases security updates on the second Tuesday of each month, commonly known as Patch Tuesday” (Regan, 2013) With the abundance and frequency of patches it’s important for our organization to manage them in an efficient and organized manner so that we maintain the highest levels of productivity while minimizing system downtime.

  • Systems Development Life Cycle ( Sdlc )

    829 Words  | 2 Pages

    The Systems Development Life Cycle (SDLC) consists of phases used in developing a piece of software. It is the plan of how to develop and maintain software, and when necessary, replace that software. In 2007 during my hospital’s transition to a new software system, I was fortunate enough to be included in the process. I did not get involved until the implementation phase, but from then on, until now, I remain very active in the process. I decided to highlight the Waterfall Model of SDLC. The Waterfall Model is a “sequential development process” with each phase continuing in a line (McGonigle and Mastrian, 2012, p. 205).

    Given the time, it takes to develop large sophisticated software systems it not possible to define the problem and build the solution in a single step. Requirements will often change throughout a projects development, due to architectural constraints, customer’s needs or a greater understanding of the original problem. Iteration allows greater understanding of a project through successive refinements and addresses a projects highest risk items at every stage of its lifecycle. Ideally each iteration ends up with an executable release – this helps reduce a projects risk profile, allows greater customer feedback and help developers stay focused.

    The software maintenance process is a long-term support tier for any and all computer-based business systems. In the age of computer automation and electronic commerce, many businesses have become dependent upon scalable and error proof software platforms. The ongoing support of these systems by the software manufacturer is crucial for the business owner, and the software's longevity. Software Maintenance is a detailed process for weighing suggested program additions, making program updates, supporting user-related questions, and fixing latent errors. This process is both heavily time and resource consuming for software firms. This is why it is important for all software firms to have a strong and well-organized software maintenance plan, in which any changes to a given product are, to be followed.
