...Iteration Planning What is it? The purpose of the iteration planning meeting is for the team to commit to the completion of a set of the highest ranked product backlog items. This commitment defines the iteration backlog and is based on the team's velocity or capacity and the length of the iteration timebox. Who does It? Iteration planning is a collaborative effort involving these roles: • Scrum master - facilitates the meeting. • Product owner - represents the detail of the product backlog items and their acceptance criteria. • Delivery team/agile team - define the tasks and effort necessary to fulfill the commitment. Preparing for iteration planning How can a team best prepare for an iteration planning meeting? Before getting started we need to ensure: • The items in the product backlog have been sized by the team and assigned a relative story point value. • The product backlog is stack ranked to reflect the priorities of the product owner. • There is a general understanding of the acceptance criteria for these ranked backlog items. The product backlog & iteration planning The product backlog addresses existing functionality and new functionality. The order in which a product backlog item is scheduled is completely independent of its ancestry. We can further generalize and say that, for the purpose of iteration planning, the important attributes for a product backlog item are: • It is small enough to be completed in the iteration...

...Explain The Scrum method as it relates to the software development process. Scrum is a framework that can be viewed as a structure that supports the construction of a complex product development. Scrum is: Lightweight, Simple to understand and difficult to master. It is a framework within which you can employ various processes and techniques. The Scrum framework consists of Scrum Teams and their associated roles, events, artifacts, and rules. Each component within the framework serves a specific purpose and is essential to Scrum’s success and usage. Scrum Theory Scrum is founded on empirical process control theory, or empiricism. Empiricism in laymen’s terms means a method of study relying on things you have experienced; stuff you can see and touch. Scrum employs a repetitious, incremental approach (a little more is added each time) to optimize predictability and control risk. Three pillars uphold every implementation of empirical process control: transparency, inspection, and adaptation. The Scrum Team The Scrum Team consists of a Product Owner, the Development Team, and a Scrum Master. Scrum Teams are self-organizing and cross-functional. Self-organizing teams choose how best to accomplish their work, rather than being directed by others outside the team. The Product Owner-The Product Owner is responsible for maximizing the value of the product and the work of the Development Team. Development Teams- have the following characteristics: • They are self-organizing. No...

...Software Design and Documentation Fall 2010 Rohan Dhruva Question A: Songbird is a free and open source software audio player, whose development is sponsored by POTI Inc. Their mission is stated as "to incubate Songbird, the first Web player, to catalyse and champion a diverse, open Media Web." Songbird utilizes the cross-platform frameworks, Mozilla's XULRunner and GStreamer media framework, and is largely capable of running on Microsoft Windows, Apple Mac OS X, Solaris and Linux. The user interface of Songbird is similar to that of Apple iTunes. It also supports syncing its music library to iPods. Hence, many people have started using Songbird as an alternative to the closed source and bloated iTunes. Songbird can be downloaded from http://getsongbird.com/ User Stories: While Songbird has robust music library management, and can import the files on your hard disk to this library, it lacks the feature of importing songs from the iTunes library. This deters many new users from switching over to Songbird, because they fear losing their play count, “starred” songs, and stored metadata like lyrics and album information. Essentially all this information should be stored with the audio file itself, by making use of ID3 tags. iTunes, however, chooses to maintain this information both in its proprietary “itl” format, and as an XML file. To ease the transition for new users, Songbird should support importing from the user’s iTunes library. The other...

...------------------------------------------------- Challenges in moving over to Agile methodology in Tata Steel ------------------------------------------------- ------------------------------------------------- Agile software development Agile software development is a group of software development methods in which solutions evolve through collaboration between self-organizing,[1] cross-functional teams. It promotes adaptive planning, evolutionary development, early delivery, continuous improvement, and encourages rapid and flexible response to change.[2] The Manifesto for Agile Software Development,[3] also known as the Agile Manifesto, was first proclaimed in 2001, The Agile Manifesto[edit] In February 2001, 17 software developers (see below) met at the Snowbird resort in Utah to discuss lightweight development methods. Individuals and interactions over Processes and tools Working software over Comprehensive documentation Customer collaboration over Contract negotiation Responding to change over Following a plan Agile principles[edit] The Agile Manifesto is based on 12 principles:[14] 1. Customer satisfaction by early and continuous delivery of useful software 2. Welcome changing requirements, even late in development 3. Working software is delivered frequently (weeks rather than months) 4. Close, daily cooperation between business people and developers 5. Projects are built around motivated individuals, who should be trusted 6. Face-to-face conversation...

...Agile Process Agile process is a collection of software development methods that encourages a software development team to be adaptable to constant change in project requirement. It requires stakeholders communicate to each other regularly, prioritize required features, develop working software in iteration, and design the system to handle quick response to change. To adapt agile methodologies, customer representatives, managers and software developers need to sit in close proximity to build consensus. The working environment typically equipped with whiteboards that are used for brainstorming, design sessions and displaying information related to the project. Throughout the project, the team uses limited formal documentation to record all design and software changes. Such environment stimulates communication, and empowers stakeholders to make tough business, people and technical decisions as project progresses. In addition, it allows the team to have short and effective daily standup meeting (scrum) to share their daily work process and roadblocks. In agile process, all stakeholders work together to evaluate and priorities all features that customer wants. Customer representatives write high level description of individual functions they want in a given software feature (user stories) and work with software development team to finalize and prioritize them. Throughout the iterative design and implementation phase of these features, the development team will evaluate...

...Rallying with Rally Project Management gets little better with the aid of tools. In traditional project, there were lots of tools aimed to draw a huge project plan running into thousands of lines. They were designed to track efforts, schedule, cost, overrun etc. bundled with numerous other features. When I explored to find out lifecycle management tool to use for my agile project, I found myself swamped with both open source and licensed tools. It took a while for me to remove the weeds. Yet, there were still a large number of choices that were in the race. Finally, I decided to implement Rally. Rally was one of the earliest pioneers in implementing an application lifecycle management tool to support the agile development. There has been a consistent addition of features since inception to support large scale projects and programs. Rally supports four different types of editions namely Community Edition, eXpress Edition, Enterprise Edition and Unlimited Edition Supported features and the appropriate pricing varies, with Community Edition being the minimum and the Unlimited Edition as maximum. Rally, indeed has made Community edition free for up to 10 users with the intention of allowing users to get a glimpse of what it has to offer for Agile community. I am listing out the top three impressive features which made me to choose Rally for my project. Usability: Rally uses a Web based thin client with appealing User Interface Design. Overall look and feel is good with solid performance...

...SCRUM Development “SCRUM” is an agile developmentally framework that allows teams to adapt the changing nature requirements by delivering software in small pieces that can be used to garner feedback from stakeholders and users this improves the quality of the final product as well as reducing risks and allowing return on investments be realized sooner. The term “SCRUM” comes from the idea of using holistic or rugby approach where a team tries to go the distance as a unit passing the ball back and forth. The biggest benefits of SCRUM and agile software development is the transparency that scrum permits scrum gives one ways to expose what is going on in the situation, the second advantage is you can actually do something about it since you know what is going on in a situation. The third benefit is that things improve, scrum doesn’t solve problems but it addresses the problems or issues at hand so that an organization can fix the problem before it gets our of hand. Agile Scrum is able to work with any technology/programming language, which provokes flexibility with technology. SCRUM helps companies save time and money, which is very crucial for any company. The overhead coast in terms of process and management is minimal thus leading to a quicker cheaper result. With any product there are always disadvantages, the disadvantages of SCRUM is if any of the team members leave during a development it can have a huge inverse effect on the project development. Inexperienced resources...

...In this post, I would like to expand upon benefits and illustrate why they are compelling reasons to consider Agile. These benefits of agile software development include: Stakeholder Engagement Agile provides multiple opportunities for stakeholder and team engagement – before, during, and after each Sprint. By involving the client in every step of the project, there is a high degree of collaboration between the client and project team, providing more opportunities for the team to truly understand the client’s vision. Delivering working software early and frequently increases stakeholders' trust in the team's ability to deliver high-quality working software and encourages them to be more deeply engaged in the project. Transparency An Agile approach provides a unique opportunity for clients to be involved throughout the project, from prioritizing features to iteration planning and review sessions to frequent software builds containing new features. However, this also requires clients to understand that they are seeing a work in progress in exchange for this added benefit of transparency. Early and Predictable Delivery By using time-boxed, fixed schedule Sprints of 1-4 weeks, new features are delivered quickly and frequently, with a high level of predictability. This also provides the opportunity to release or beta test the software earlier than planned if there is sufficient business value. Predictable Costs and Schedule Because each Sprint is a fixed duration, the...

...Riki Shafier Professor Kimberlee Hoftiezer SOS-110 24 January 2016 Music Education: A Personal Journey For the past few years I have been taking different courses, learning many things and preparing myself for the life ahead of me. As a soon-to-be college graduate, the future beckons, bright and inviting. There are endless career opportunities that await those who have put forth the effort to receive an education. The career goals toward which I am currently preparing are to become a highly sought-after piano teacher and piano-teacher trainer with a full roster of students, complete with a waiting list for those who wish to join my studio. I plan to build a fully- developed business model for my piano studio. This plan will include curricula for various ages and skill levels, as well as plans for accommodating specific needs of individual students. The plan will also have processes for the acceptance and rejection of potential students, registration and payment options, and online booking opportunities. This will be optimized through the use of technology. Technology, in all its many forms, has transformed the world we live in, and I anticipate that it will prove to be of great use to me in the development of my career goals. In the short-term, I will be able to train under experienced piano educators and teacher-trainers via Skype lessons and workshops, and use various training software programs to improve my technical and teaching skills. Additionally, I plan to...

Cook. Manufactured in the United States of America. Preface You will find this book to be somewhat unusual. Most computer science texts will begin with a section on the history of computers and then with a flurry of definitions that are just “so many words” to the average student. My approach with Blue Pelican Java is to first give the student some experience upon which to hang the definitions that come later, and consequently, make them more meaningful. This book does have a history section in Appendix S and plenty of definitions later when the student is ready for them. If you will look at Lesson 1, you will see that we go right to work and write a program the very first day. The student will not understand several things about that first program, yet he can immediately make the computer do something useful. This work ethic is typical of the remainder of the book. Rest assured that full understanding...

...Researching Variable Naming Rules Visual Basic You must use a letter as the first character. You can't use a space, period (.), exclamation mark (!), or the characters @, &, $, # in the name. Name can't exceed 255 characters in length. Generally, you shouldn't use any names that are the same as the functions, statements, and methods in Visual Basic. You end up shadowing the same keywords in the language. To use an intrinsic language function, statement, or method that conflicts with an assigned name, you must explicitly identify it. Precede the intrinsic function, statement, or method name with the name of the associated type library. For example, if you have a variable called Left, you can only invoke the Left function using VBA.Left. You can't repeat names within the same level of scope. For example, you can't declare two variables named age within the same procedure. However, you can declare a private variable named age and a procedure-level variable named age within the same module. Python Must begin with a letter (a - z, A - B) or underscore (_) Other characters can be letters, numbers or _ Case Sensitive Can be any (reasonable) length There are some reserved words which you cannot use as a variable name because Python uses them for other things.- See more at: http://www.w3resource.com/python/python-variable.php#sthash.5AXuVlWN.dpuf Java Variable names are case-sensitive. A variable's name can be any legal identifier — an unlimited-length...
