Process planning

Selection of the appropriate software life cycle model (for example, spiral, evolutionary prototyping) and the adaptation and deployment of appropriate software life cycle processes are undertaken in light of the particular scope and requirements of the project. Relevant methods and tools are also selected. At the project level, appropriate methods and tools are used to decompose the project into tasks, with associated inputs, outputs, and completion conditions (for example, work breakdown structure). This in turn influences decisions on the project’s high-level schedule and organization structure.

Determine deliverables

The product(s) of each task (for example, architectural design, inspection report) are specified and characterized. Opportunities to reuse software components from previous developments or to utilize off-the-shelf software products are evaluated. Use of third parties and procured software are planned and suppliers are selected.

Effort, schedule, and cost estimation

Based on the breakdown of tasks, inputs, and outputs, the expected effort range required for each task is determined using a calibrated estimation model based on historical size-effort data where available and relevant, or other methods like expert judgment. Task dependencies are established and potential bottlenecks are identified using suitable methods (for example, critical path analysis). Bottlenecks are resolved where possible, and the expected schedule of tasks with projected start times, durations, and end times is produced. Resource requirements (people, tools) are translated into cost estimates. This is a highly iterative activity which must be negotiated and revised until consensus is reached among affected stakeholders (primarily engineering and management).

Resource allocation

Equipment, facilities, and people are associated with the scheduled tasks, including the allocation of responsibilities for completion. This activity is informed and constrained by the availability of resources and their optimal use under these circumstances, as well as by issues relating to personnel (for example, productivity of individuals/teams, team dynamics, organizational and team structures).

Risk management

Risk identification and analysis (what can go wrong, how and why, and what are the likely consequences), critical risk assessment (which are the most significant risks in terms of exposure, which can we do something about in terms of leverage), risk mitigation and contingency planning (formulating a strategy to deal with risks and to manage the risk profile) are all undertaken. Risk assessment methods (for example, decision trees and process simulations) should be used in order to highlight and evaluate risks. Project abandonment policies should also be determined at this point in discussion with all other stakeholders. Software-unique aspects of risk, such as software engineers’ tendency to add unwanted features or the risks attendant in software’s intangible nature, must influence the project’s risk management.

I want to know about prototype model in software engineering
Malli Reply
Prototype Model is a replica model. In this we plan and build a rough application. Further we launch it for users and if they give their feedback or need any enhancement then we add-on requested features as per the system/user requirements.

between JavaScript and html,which is the best to master first?
Njuguna Reply
You have to master HTML first before you do javascript. Actually Html is not a programming language it is used to make a skeleton of a webpage
