Software Development : The Spiral Model Essay

Overall, the complete redesign can be applied to the software development process which aids in reducing costs, reducing cycle time, improves

“Organizational Management and Leadership” defines planning as “the development of goals, which leads to the development of an overall strategy for achieving those goals. Planning can be performed at all levels of an organization. Supervisors are planning when a weekly work schedule is put together for hourly staff. Top executives are planning when they define the mission statement of the company and determine how the organization can maintain its competitive advantage.”

Planning: It is a process which involves setting the aims, mission statement and objectives of the organization and how they will be achieved. Nothing can be achieved without proper planning. Planning outlines what tasks to do, when to do it and how to perform the tasks. Planning is based on the short and long term successes of the organization (Purnell,

A: In the software lifecycle there are 4 phases that are derived from the old System Development Life Cycle (SDLC) and they are as follow; Planning, Implementation, Maintenance, and the Removal process. The planning phase is defined by all planning activities including the analysis of the software to be installed, verification of its compatibility, supported methods of installations, and the identification of any risks associated with the software and the desired deployment method. The Implementation phase is used to prepare for deployment such as; creating a shared access location for files and creating or using the appropriate package files. After all these steps have been

Goals in planning involve completing the project on time and under budget, with a high quality of workmanship. Determining and organizing available resources involves preparing contracts for sub-contractors and choosing a site superintendent. Daily correspondence with the site

Planning is defined as choosing a goal and developing a strategy to attain that goal.

Planning work establishes exactly what work you are required to do and to what standard/target, it also allows you to establish time limits.

The primary purpose of planning, is to establish a set of directions in sufficient detail to tell the project team exactly what must be done, when it must be done, what resources will be required to produce the deliverables of the project, successfully, and when each resource will be needed (Jack R .Meredith & Samuel j. Mantel, 2009). Budgeting and cost estimating are important tools when doing a project plan. A budget is always needed in the plan. A budget is a plan for allocating resources. Thus, according to Jack R Meredith the act of budgeting is the allocation of scarce resources to the various endeavors of an organization. (Jack R .Meredith & Samuel j. Mantel, 2009)

Plan - During planning you must completely plan out how your intent to create your solution to your defined problem. You must come up with concrete drawings, material list, process charts, and

As the world became more and more dependent on technology with each passing day, software automatically became an important organ for development. Since software is needed almost everywhere today, its development is a highly intelligent and precise process, involving various steps. Known as software development life cycle, these steps include planning, analysis, design, development & implementation, testing and maintenance. These steps go on to create the perfect software for clients. ”

“Project planning is the process of establishing the scope, defining the objectives and steps to obtain them. It is one of the most important of the processes that make up project management. The output of the project planning process is a project management plan,” (Teamgantt.com, 2017).

More software projects have gone awry for lack of calendar time than for all other causes combined (Brooks, 1995). Why is this cause of disaster so common? Statistics show that schedule delays occur in about 70% of software projects, cost overruns are above 90%, and the time scheduled for large-scale development projects is exceeded by an average of between 20% and 50%. Lastly, the larger the project, the more likely it is that its budget will exceed what was originally planned (Junguang, Ruixia, & Estrella, 2015). On completion of any project, a risk section should be provided for the Project Lessons Learned Report, detailing risks that might affect other similar projects, together with responses that have been found

As a result of the Software Development Industry struggling to deal with the complexities of developing software within a hypercompetitive market, projects continue to fail at an alarming rate. According to the Standish Group 's CHAOS Manifesto 2012 report, project statistics across the United States and Europe were analyzed to determine if the projects were successful, challenged or failed. The results of the report found that only 37% of all IT projects were successful (on time, within budget and included the required functionality); 42% were challenged (delivered late, over budget and/or with less functionality then required); and 21% failed and had to be cancelled prior to completion and/or were never implemented (Standish, 2012).

Planning provides a guideline for the members of an organisation to carry out their tasks according to the set objectives. The absence of planning can create ambiguity within the organisation.

In software development, there are various types of methods that developers follow in order to produce valuable software. From the many types of methods that exist today, the industry standard that is mostly followed today is the software development lifecycle (SDLC). The SDLC is a process that software development companies utilize in order to design, develop and test software during production. Within the SDLC, there are different test models that developers can utilize based on their business and development requirements. Currently today, the most common models include the waterfall, iterative, spiral and V-model. Regardless of the model that a developer decides to utilize, all the phases will be the same, which would begin with the first step and that is the requirement gathering and analysis phase.
