Scrum is an agile software development method. The name “Scrum” is a term from rugby, and it’s used as a metaphor to reflect the degree of cooperation needed to succeed. So scrum is a Team pack in rugby where everyone in the pack acts together to move the ball down the field.

Waterfall model is the most frequently interpreted as a purely sequential process model. In this model design does not start until there is not a complete set of requirements, coding and coding does not start until completion of an exhaustive critical design review.

Spiral model is a combination of prototype and sequential model or waterfall model. This model uses same phases as the waterfall model and the same order which is separated by planning, risk assessment and building of prototypes and simulations.

Backtracking is a general algorithm for finding all solutions to some computational problems. It does not allow in waterfall model for correcting errors detected during analysis, design and implementation. But, it is allow in iterative and incremental development approaches.

– JAD (Joint Application Development) is a methodology that involves the client or end user in the design and development of an application, through a succession of collaborative workshops called JAD sessions.

– RAD application development methodology goes further than JAD in reducing the time taken to develop an application, is not always as structured as the JAD and focuses more on software development than JAD

– Computer-aided design (CAD), is the use of computer systems to assist in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing.

The chaos strategy is a strategy of software development based on the chaos model. The main rule is always resolve the most important issue first.
– An issue is an incomplete programming task.
– The most important issue is a combination of big, urgent, and robust.
-Big issues provide value to users as working functionality.
– Urgent issues are timely in that they would otherwise hold up other work.
-Robust issues are trusted and tested when resolved. Developers can then safely focus their attention elsewhere.
– To resolve means to bring it to a point of stability.

In software engineering, software configuration management i.e SCM or S/W CM is the task of tracking and controlling changes in the software, part of the larger cross-disciplinary field of configuration management. SCM practices include revision control and the establishment of baselines.

The goals of SGM are:
– Configuration identification
– Configuration control
-Configuration status accounting
– Configuration auditing
– build management
– process management
– Environment management
– Teamwork
– Defect tracking

Software maintenance is the modification of a software product after delivery to correct faults, to improve performance, functionality, to adapt the product to a change environment.

The CMM is Capability Maturity Model. It is a methodology used to develop and refine an organization’s software development process.

CMMI(Capability Maturity Model Integration) has an iterative lifecycle that integrates the latest best practices from the industry and attacks risks in process architecture at an early stage.

Destructive software testing is a type of software testing which attempts to cause a piece of software to fail in an uncontrolled manner, in order to test its robustness.
Following types of destructive testing:
-Stress tests: Stress testing is a software testing activity that determines the robustness of software by testing beyond the limits of normal operation.
-Crash tests
-Hardness tests
– Metallographic tests

Capability Maturity Model Integration (CMMI) is a process level improvement training and appraisal program.

ISO 9000 is a set of international standards on quality management and quality assurance developed to help companies effectively document the quality system elements to be implemented to maintain an efficient quality system.

The ISO 15504 International standard is a Framework for doing Process Maturity Assessments and continuous Improvement.

Incremental model is a type of software development model.

Incremental Funding Methodology(IFM) heuristics provide clarity into important metrics i.e project level NPV, ROI, initial start-up investment costs, and time needed for a project to reach self-funding status.
Incrementatl funding methodology (IFM) takes into consideration all but not Opportunity cost.

White board architecture is not a valid software engineering architecture.

Non functional requirement of a web based application is when the user clicks a “read me” link, the next page should be opend within 5 seconds.

The Unified Software Development Process or Unified Process is a popular iterative and incremental software development process framework.

The Personal Software Process (PSP) is a structured software development process.

Rational Rose, Rhapsody, Telelogic Tau G2 UI Design Tools – Rapid/Paper prototypes, Simple SUMI (Software Usability Measurement Inventory are the design tools.

Extended Enterprise Modeling Language (EEML) is commonly used for business process modeling across a number of layers.

SysML is a Domain-Specific Modeling language for systems engineering that is defined as a UML profile (customization).

Unified Modeling Language (UML) is a general-purpose modeling language.

Data Manipulation Language (DML) statements are used for managing data in database.

The Extreme Programming(XP) is commonly used agile process model.

Large or complex functionalities are more easily understood when broken down into pieces using functional decomposition. Functional decomposition is a business analysis technique for breaking down a “business operation” into functional components.

The Constructive Cost Model (COCOMO) is an algorithmic software cost estimation model developed by Barry Boehm.

The umbrella activities in a software development life cycle process are as follows:
-Software Project Management
-Formal Technical Reviews
-Software Quality Assurance
-Software Configuration Management
-Re-usability Management
-Risk Management
-Measurement and Metrics
-Document Preparation and Production
