  • It makes sure that the product is designed to deliver all functionality to the customer.
  • Verification is done at the starting of the development process. It includes reviews and meetings, walkthroughs, inspection, etc. to evaluate documents, plans, code, requirements and specifications.
  • Suppose you are building a table. Here the verification is about checking all the parts of the table, whether all the four legs are of correct size or not. If one leg of table is not of the right size it will imbalance the end product.Similar behavior is also noticed in case of the software product or application. If any feature of software product or application is not up to the mark or if any defect is found then it will result into the failure of the end product. Hence, verification is very important. It takes place at the starting of the development process.

  • Software verification and validation
    Software verification and validation
  • It answers the questions like: Am I building the product right?
  • Am I accessing the data right (in the right place; in the right way).
  • It is a Low level activity
  • Performed during development on key artifacts, like walkthroughs, reviews and inspections, mentor feedback, training, checklists and standards.
  • Demonstration of consistency, completeness, and correctness of the software at each stage and between each stage of the development life cycle.
According to the Capability Maturity Model(CMMI-SW v1.1) we can also define verification as the process of evaluating software to determine whether the products of a given development phase satisfy the conditions imposed at the start of that phase. [IEEE-STD-610].
Advantages of Software Verification :
  1. Verification helps in lowering down the count of the defect in the later stages of development.
  2. Verifying the product at the starting phase of the development will help in understanding the product in a better way.
  3. It reduces the chances of failures in the software application or product.
  4. It helps in building the product as per the customer specifications and needs.

Obtained from https://www.archtoolbox.com/images/represent/gantt-chart.png ( Copyright ©   Arch Media Group LLC) Also read: Project Planning and Scheduling Visual Depiction of Schedule: Gantt Chart Project schedules are most commonly depicted through the use of Gantt charts. Gantt charts break down the project into individual tasks, each of which is represented by a horizontal bar. The timescale of the project travels from left to right, with the left edge of the bar representing the start date of the task and the right edge of the bar representing the completion date. The bar length between the start and the end makes up the duration of that specific task. Arrows are typically drawn from the end of one task to the start of another task that is dependent on the task that proceeded it (predecessor to successor). Similar to the CPM method above, a critical path will become apparent based on the duration of the various linked project paths. Creation of a Gantt chart is rel...

Also read Critical Path Method ( Copyright ©   Arch Media Group LLC) The critical path method, abbreviated as CPM, is the most commonly used type of scheduling technique in the construction industry. The critical path method is built around the use of predecessors and successors for each construction task needed to accomplish the job. Most tasks (except the initial task) will have one or more predecessors that need to be accomplished before that task can start. If we select a certain task, such a framing a house, we need to determine what must occur before the framing can be constructed. In this case the ground floor slab will need to be finished before the framing can be placed on top of it. Therefore, creation of a ground floor slab is the predecessor of the house framing task. Conversely, framing the house is a successor of the ground floor slab construction. Following the placement of tasks in the schedule, along with the creation of linkages between the predecessor a...
