  • Annual Report 2011
    ANNUAL REPORT 2011 TO OUR STOCKHOLDERS: I am pleased to report that KLA-Tencor performed at record levels on several fronts in fi scal year 2011. We achieved company records in our most critical fi nancial metrics, including revenues, net income, earnings per share and profi t margins, and our year-over-year revenue growth signifi cantly exceeded that of our peer group and our industry. At the same time, we generated record free cash fl ow and continued to deliver meaningful returns to our stockholders in the form of dividends and stock repurchases. This performance was the result of our unwavering focus on develop- ing market-leading technology, addressing our customers’ most critical needs and driving operational effi ciency. Though our industry has seen a recent slowdown in demand, we remain very excited about KLA-Tencor’s prospects for the future. The long-term demand drivers for KLA-Tencor and our industry remain intact, and we are well positioned to grow as demand for semiconductor capital equipment recovers. Our record results in fi scal year 2011 demonstrate that our strategies are working. Looking back over our 35-year history, we have established a pattern of achievement and leadership, which has enabled us to create the strong foundation from which we now look ahead to the future. Our accomplishments during fi scal year 2011 in each of our four strategic objectives (Customer Focus, Growth, Operational Excellence and Talent Development) are highlighted below: CUSTOMER FOCUS: MARKET LEADERSHIP Our customer focus strategic objective is measured in customer satisfaction and market share. We maintained our market leadership positions among our foundry and logic customers in fi scal year 2011 and improved our market position in memory, as evidenced by achieving record new order levels across all our end markets during the year.

Fields of application for such systems, amongst others, range from large scale, distributed enterprise solutions down to modularised embedded systems. The presented work was moti- vated by the complex design process of avionics for unmanned systems, where the increased demand for enhanced system autonomy implies high levels of system collaboration and infor- mation exchange. For such system designs a clear separation between the application logic implemented by system components, the means of interaction between them and finally the realisation of such communication on target platforms is essential. In particular, this sep- aration leads to simplification of the complex design processes and increases the individual components’ re-use potential.

  • 1. the Scope of Life Cycles 2
    http://www.ambysoft.com/essays/agileLifecycle.html http://www.implementingscrum.com/2006/09/11/the-classic-story-of-the-pig-and-chicken/ http://www.agiledata.org/ http://www.agiledata.org/essays/agileDataModeling.html http://mike2.openmethodology.org/w/index.php/Category:Software_Delivery_Lifecycle Projectsmart http://www.projectsmart.co.uk/ m often asked by clients to facilitate workshops overviewing the ideas presented in the Agile Manifesto and agile techniques such as Test-Driven Design (TDD), database refactoring, and agile change management. One issue that many people seem to struggle with is how all of these ideas fit together, and invariably I found myself sketching one or more pictures which overview the life cycle for agile software development projects. I typically need one or more pictures because the scope of life cycles change -- some life cycles address just the construction life cycle, some address the full development life cycle, and some even address the full IT life cycle. Depending on your scope, and how disciplined your approach to agile software development is, you will get different life cycle diagrams. The goal of this article is to describe the agile system development life cycle (SDLC), putting it in context from what you may have heard about within the agile community and more importantly within the context of your overall IT efforts. This article covers: 1. The scope of life cycles 2. Iteration -1: Pre-project planning 3. Iteration 0: Project inception 4. Construction iterations 5. Release iterations 6. Production 7. Retirement 1. The Scope of Life Cycles As we described in the book The Enterprise Unified Process (EUP) the scope of life cycles can vary dramatically.

  • IBM ® Rational ® Rapid Developer Technical Overview
    A Technical Discussion of Rational Rapid Developer Technical Overview July, 2003 IBM® Rational® Rapid Developer Technical Overview James R. Farrell [email protected] Executive Summary The Internet has brought a major revolution in business and technology. It provides the ubiquitous business dial tone that has the potential to automate and transform every aspect of business. Businesses are connected on a real- time basis with customers, vendors, partners and employees. Every aspect of your business is likely to change including business models, types of products and services offered, pricing models, and business relationships. A parallel change is occurring on the technology side. Your applications use n-tier deployment architectures to achieve 24 x 7 availability, and need to be highly scalable and secure. The technology to power your applications is likely to keep changing rapidly. This has an obvious impact on your application development environment. As an application developer you need to anticipate a changing environment in which business and technology become more complex. The vital business processes of today’s organizations increasingly depend on software. Organizations must be able to adapt their software assets rapidly to meet challenges and opportunities as they come along. The ability to generate reliable, scalable business applications has a direct correlation with the ability to respond to both internal and external customer demands. For many organizations, business applications are the most critical software assets, because they reflect the core competency of an organization and are essential for maintaining a competitive edge. Today’s smart organizations are connecting business applications to their customers, vendors, and other partners; they’re connecting the many departments, locations, and people within the enterprise; and they’re making the growing enterprise responsive to the needs of the business.
