What are 7 steps of the Waterfall Model?

1. System Requirements

2. Software Requirements

3 - 7. ?????????????????????????????

Establishes the components for building the system.

Establishes the expectations for software functionality and identifies which system requirements the software affects.

Determines the software framework of a system to meet the specified requirements.

The design defines the major components and the interaction of those components.

But the design does not define the structure of each component.

Examines the software components defined in the architectural design.

Produces a specification for how each component is implemented.

Implements the detailed design specification.

Determines whether the software meets the specified requirements and finds any errors present in the code.

Addresses problems and enhancement requests after the software releases.

Uses the same phases as the pure waterfall, but is not done on a discontinuous basis.

Enables the phases to overlap when needed.

Modified Waterfall can go back.

If there is an error within one of the phases, they can go back, check and continue the process again.

Emphasizes risk management so you find major problems earlier in the development cycle.

In Spiral Mode, you break up the project into a set of __ that need to be dealt with.

You then begin a series of _________ in which you analyze the most important risk, evaluate options for resolving the risk, deal with the risk, assess the results, and plan for the next iteration.

What are the Six steps of Spiral Model?

1. Determine objectives, alternatives, and constraints

Are any issues that are not clearly defined or have the potential to affect the project adversely.

For each risk, consider the 2 steps:

1. The likelihood of the risk occurring (_________)

2. The severity of the effect of the risk on the project (_________)

Uses multiple iterations of requirements gathering and analysis, design and prototype development.

If you don't use a methodology, it's likely you are doing this.

It is very dangerous as there is no way to assess progress, quality or risk.

It rarely produces useful results.

Strengths of Code-and-Fix:

1. No time spent on "________" like planning, documentation, quality assurance, standards enforcement or other non-coding activities.

2. Requires little ___________.

Weaknesses of Code-and-Fix:

1. Dangerous.

2. No means of ______________ or identifying risks.

3. ________________ in approach do not show up quickly, often requiring work to be thrown out.

Following requirements definition, analysis must be done to compare the package to the business, functional and architectural requirements.

Strengths of Commercial-Off-the-Shelf:

Available ____________ and usually at far lesser cost.

Weaknesses:

Will rarely satisfy all ______________.

A method for developing web applications.

In Agile Model, the tasks are divided to ________ (small time frames) to deliver specific features for a release.

In _________, iterative approach is taken and working software build is delivered after each iteration. Each build is __________ in terms of features; the final build holds all the features required by the customer.

Waterfall features distinct phases with _________ and ___________ at each phase, while agile methods have iterations rather than phases.

Waterfall features distinct phases with checkpoints and deliverables at each phase, while agile methods have ________ rather than phases.

Architectural Design determines the software ________ of a system to meet the specified requirements.

In Spiral Model, you have to complete the design before you begin coding.

This model believes that every project needs to be _____________and the existing methods need to be ________ to best suit the project requirements.

In Evolutionary Prototyping,

After each iteration, the result is ________ by the customer.

Their response creates the __________ of requirements and defines the next iteration.

In some organizations, a _________ maintains the quality of the product by reviewing each change made in the maintenance stage.
