The document presents information on the Spiral Model software development process. It discusses that the Spiral Model combines elements of the prototype model and waterfall model. It involves dividing the process into task regions like customer communication, planning, risk analysis, engineering, and construction. Each task region results in further refinement through iterations of the spiral. The Spiral Model allows for risk analysis and adding new features throughout the process.
The document discusses the spiral model of software development. The spiral model is an iterative approach that combines prototyping and aspects of the waterfall model. It was defined by Barry Boehm in 1988 as a way to address risks through iterative evaluation and improvement of prototypes. The spiral model is best for medium to high risk projects where requirements are complex or expected to change. It involves evaluating prototypes, defining new prototypes based on learnings, and repeating this process until the final product is delivered.
Proyecto de fisica "Puentes colgantes"zaira ortega
El documento describe los diferentes tipos de puentes, incluyendo puentes en viga, en ménsula, en arco, colgantes y atirantados. Explica que un puente colgante está compuesto por cables de acero que soportan el tablero a través de tirantes verticales, y que las fuerzas principales son la tracción en los cables y la compresión en los pilares.
Here are the sequences that would result from applying each priority rule to the jobs:
FCFS: A, B, C
SPT: A, C, B
LPT: B, A, C
EDD: B, A, C
TSPT: A, C, B
LS: A, B, C
COVERT: B, A, C
The FCFS, EDD, LS and COVERT rules all produce the same sequence of B, A, C since job B has the earliest due date. The SPT and TSPT rules sequence A first since it has the shortest processing time. Only the LPT rule sequences the jobs in the opposite order of B
This document provides information about ISO 9001:2008, which establishes standards for quality management systems. It discusses the key aspects of a quality management system that are evaluated during external audits, including quality processes, management responsibility, resources, product realization, and measurement/improvement. The document outlines the roles of the ISO manager and executive, how internal audits are conducted, what is expected during an external audit, and environmental practices related to ISO standards.
This document discusses an approach to visualizing and analyzing variability in the execution time of business processes based on product lines. The approach defines business processes using products, allowing for higher-level questions and visualizations. It presents a conceptual framework for researching the analysis of business process definitions through timing diagrams and visualization versus analysis. The goal is to visualize and analyze business process definitions to understand variability from inclusion and exclusion of subprocesses in different contexts.
The document discusses measuring processor performance, identifying the memory hierarchy, and benchmarking performance. It describes examining processor specifications, identifying processor performance through parameters like branch mispredictions and instruction execution time. It also explains understanding the memory hierarchy, analyzing issues affecting memory performance, and using benchmarks like single stream benchmarks and throughput benchmarks.
The document discusses the key components and concepts of software testing. It covers people, processes, infrastructure, testing methodologies, test planning and execution, defect tracking, metrics, and more. The core elements of testing include testing strategies, requirements tracing, test case development, test environment setup, test execution, and results reporting. Different types of testing are also outlined such as unit testing, integration testing, functionality testing, and volume testing.
This document discusses internationalization (i18n) which refers to adapting software, content, or products to support worldwide markets and locales. It outlines the business benefits of i18n including increased sales opportunities and reduced costs. The technical aspects of i18n like supporting different character sets, languages, and cultural formats are also examined. The document emphasizes that i18n is an ongoing process that requires planning, tools, and coordination between development, testing, and localization teams.

15. An Agile View of Process
Represents a reasonable compromise between conventional software
engineering for certain classes of software and certain types of
software projects
Can deliver successful systems quickly
Stresses continuous communication and collaboration among
developers and customers
Embraces a philosophy that encourages:
customer satisfaction,
incremental software delivery,
small project teams (composed of software engineers and stakeholders),
informal methods, and
minimal software engineering work products
Stress on-time delivery of an operational software increment over
analysis and design
15 IF2036 RPL - IF ITB
16. Manifesto for Agile Software Development
Proposes that it may be better to value:
Individuals and interactions over processes and tools
Working software over comprehensive documentation
Customer collaboration over contract negotiation
Responding to change over following a plan
While the items on the right are still important the items on the left are
more valuable under this philosophy
Note: although most practitioners agree with this philosophy in theory,
many pragmatic issues surface in the real world that may cause items on
the right to be as important as items on the left
16 IF2036 RPL - IF ITB
17. 12 Principles
Highest priority: user satisfaction
Welcome changing requirement
Deliver working software frequently
Business people and developers work together daily
Build around motivated individuals
Face-to-face conversation
Working software: primary measure of progress
Promote sustainable development
Continuous attention to technical excellence and good design
Simplicity is essential
Self-organizing team
Tune and adjust team behavior at regular intervals
17 IF2036 RPL - IF ITB
18. Agile Process Models
All agile process models conform to the manifesto
and the principles
Examples:
Extreme Programming (XP)
Adaptive Software Development (ASD)
Dynamic Systems Development Method (DSDM)
Scrum
Crystal
Feature Driven Development (FDD)
Agile Modeling (AM)

Editor's Notes
Requirements analysis and definition System and software design Implementation and unit testing Integration and system testing Operation and maintenance The main drawback of the waterfall model is the difficulty of accommodating change after the process is underway. One phase has to be complete before moving onto the next phase.
