  • Is it OK to have a team with same abilities but different skill levels?

    - by A. Karimi
    I believe that in an ideal team, members should have different but complementary abilities. But is that true about software development teams? As an example we are a small team of 5. We almost have the same abilities and interests but with different levels of skills. Regarding such situation I think we don't cover our teammates' weaknesses. Is there any pattern to follow to manage and improve such team? Should I setup a team with different abilities and interests to maximize the performance and productivity? -- EDIT -- Our current team has a specific lifetime. We work together in a per-project manner. In another word we may change the team arrangement for each project depending on the project and developers situation. Actually we've provided a sort of floating situation. In short, we are a network of developers rather than a fixed-size development team.

  • Pair programming and unit testing

    - by TheSilverBullet
    My team follows the Scrum development cycle. We have received feedback that our unit testing coverage is not very good. A team member is suggesting the addition of an external testing team to assist the core team, but I feel this will backfire in a bad way. I am thinking of suggesting pair programming approach. I have a feeling that this should help the code be more "test-worthy" and soon the team can move to test driven development! What are the potential problems that might arise out of pair programming??

  • Is it okay to have people with multiple roles in a Scrum team?

    - by Wayne M
    I'm evaluating some Agile-style methodologies for possible introduction to my team. With Scrum, is it allowable to have the same person perform multiple roles? We have a small team of four developers and a web designer; we don't really have a lead (I fulfill this role), QA testers or business analysts, and all of our development tasks come from the CIO. Automated testing is seen as a total waste of time, and everything focuses on speed and not quality. What will happen is the CIO will come up with a development task (whether a feature or a bug) and give it to a developer (not to the whole team, to an individual, often in private or out of the blue) who is then expected to get it completed. The CIO doesn't gather requirements beyond the initial idea (and this has bitten us before as we'll implement something only to find out that none of the end users can use the feature, because they weren't consulted or even informed about it before we developed it, and in a panic we'll be told to revert the change) but requires say in/approval of everything that we do. First things first, is a Scrum style something to consider to introduce some standards and practices? From reading, Scrum seems to rely on a bit more trust and communication and focuses more on project management than on development, which is something we are completely devoid of as we don't have any semblance of project management at present. Second, if it can work is it unreasonable for someone, let's say myself, to act as both ScrumMaster and a developer? Or for a developer to also be the Product Owner (although chances are this will be the CIO, who isn't a developer)? I realize the Scrum Master and the Product Owner should be different people but at the same time I don't think we have anyone who has the qualities of a Product Owner (chances are it would turn into a "I need all these stories, I don't care how but get it done" type of deal and/or any freeze would be unfrozen on a whim). It seems to me that I might need to pick and choose pieces of Scrum/XP/Lean to compensate for how things are done currently, as it's highly unlikely that the mentality can be changed; for instance Pair Programming would never fly (seen as a waste, you get half the tasks done if you need two people for everything), TDD would be a hard sell, but short cycles would be welcomed.

  • Oracle At QCon SF 2012

    - by Cassandra Clark - OTN
    Oracle Technology Network is a Platinum sponsor at QCon San Francisco.  (qconsf.com).  Don’t miss these great developer focused sessions: Shay ShmeltzerHow we simplified Web, Mobile and Cloud development for our own developers? - the Oracle StoryOver the past several years, Oracle has beendeveloping a new set of enterprise applications in what is probably one of thelargest Java based development project in the world. How do you take 3000 developers and make them productive? How do you insure the delivery of cutting edge UIs for both Mobile and Web channels? How do you enable Cloud baseddevelopment and deployment?  Come and learn how we did it at Oracle, and see how the same technologies and methodologies can apply to your development efforts. Dan SmithProject Lambda in Java 8Java SE 8 will include major enhancements to the Java Programming Language and its core libraries.  This suite of new features, known as Project Lambda in the OpenJDK community, includes lambda expressions, default methods, and parallel collections (and much more!).  The result will be a next-generation Java programming experience with more flexibility and better abstractions.   This talk will introduce the new Java features and offer a behind-the-scenes view of how they evolved and why they work the way that they do. Arun GuptaJSR 356: Building HTML5 WebSocket Applications in JavaThe family of HTML5 technologies has pushed the pendulum away from rich client technologies and toward ever-more-capable Web clients running on today’s browsers. In particular, WebSocket brings new opportunities for efficient peer-to-peer communication, providing the basis for a new generation of interactive and “live” Web applications. This session examines the efforts under way to support WebSocket in the Java programming model, from its base-level integration in the Java Servlet and Java EE containers to a new, easy-to-use API and toolset that are destined to become part of the standard Java platform. The full conference schedule is here: http://qconsf.com/sf2012/schedule/wednesday.jsp But wait, there’s more!  At the Oracle booth, we’ll also be covering: ·         Oracle ADF Mobile·         Oracle Developer Cloud Service·         Oracle ADF Essentials·         NetBeans Project Easel Lastly we’ll share the results of a short cloud survey at QConSF ater this week.  If you attended this year's Oracle OpenWorld and JavaOne conferences, it would be hard not to notice that Oracle is clearly "all-in" when it comes to the Cloud.  With Cloud computing being such a hot topic on many OTN members' minds, we'd like to know what you're doing in the cloud and invite you to take this short cloud survey.

  • Review of Agile Project Management Software

    - by John K. Hines
    Bright Green Projects have an admittedly older blog post entitled Review of Agile Project Management Software | Scrum Kanban Methodology. Since I haven't had time to review Scrum project management tools in quite awhile, it was nice to find a write-up that's as succinct as this one. The thing I like the best about Bright Green's site, besides the product, is the vocabulary they use to describe Agile software development. For example, the couple Scrum with the development methodology they're using (Lean Kanban). Many organisations simply say they're using Scrum, which itself doesn't proscribe any engineering practices. It would add some clarity for teams to adopt the Scrum-Method terminology. At least then you could know if you're walking into a Scrum-Chaos situation.

  • Dadaism and Agility

    - by alexhildyard
    We all have our little bugbears, and something that has given me particular pause over the years is the place of Agility in the software development life cycle. While I have seen it used successfully on both small and Enterprise-level projects, I have also seen many instances in which long-standing technical debt has also originated under its watch. Ironically the problem in such cases seems to me not that the practitioners in question have failed to follow due process (Test, Develop, Refactor -- a common "what" of Agile), but basically that they have missed the point (the "why" of Agile). It's probably a sign of my age that I'm much more interested in the "why" than the "what", since I feel that the latter falls out naturally from the former, but that this is not a reciprocal relationship.Consider Dadaism, precursor to the Surrealist movement in the early part of the twentieth century. Anyone could stand up and proclaim he or she was Dada; anyone could write cut-ups, or pull words out a hat, or produce gibberish on duelling typewriters under the inspiration of Dada. And all that took place at such performances was a manifestation of Dada, and all the artefacts that resulted were also Dada. Hence one commentator's engimatic observation that 'when one speaks of Dada, then one speaks of Dada. But when one does not speak of Dada, one still speaks of Dada.'What is Dada? Literally, Dada is what you say it is. But that's also missing the point. Dada is about erecting a framework within which utterances like this are valid; Dada is about preparing a stage for itself. Dadaism exemplifies the purity of a process-driven ideology -- in fact an ideology that is almost pure process, with nothing extraneous in the way of formal method, and while perhaps Agile delivery should not embrace the liberties of Dadaism too literally, some of the similarities nevertheless are salutary.Agile -- like Dada -- is an attitude; it is about *being* agile; it is not really about doing a specific set of things that are somehow *part* of being Agile. It is an abstract base rather than an implementation, a characteristic rather than a factor. It is the pragmatic response to the need for change in the face of partial information, ephemeral requirements and a healthy dose of systematic uncertainty. In practice this will usually mean repeatedly making the smallest useful changes to a system, recognising that systems evolve, and that all change carries risk. It will usually mean that instead of investing effort in future-proofing a system against a known technology roadmap, one instead invests one's energies in the daily repetition and incremental development of processes best designed to accommodate change quickly. But though it may mean these things in practice, it isn't actually *about* either of these things; it's about the mindset, the attitude that conceives of such responses as sensible solutions given the larger and ultimately unclassifiable thing that constitutes the development lifecycle of a specific project.

  • Jump into Android or learn Java basics first?

    - by daniels
    I am quite proficient in C and know some C++, but never touched Java. Recently I got an idea for an app which I think has potential, and I want to develop it. I am planning to go Android first, cause it doesn't require a mac/iPhone. So my question is: can I go straight to learning Android development, picking up the Java syntax as I go along and need it (after all I don't think it's much different from C/C++), or should I take a couple of weeks to learn the basics of Java first and then start with Android development?

  • Where should the database and mail parameters be stored in a Symfony2 app?

    - by Songo
    In the default folder structure for a Symfony2 project the database and mail server credentials are stored in parameters.yml file inside ProjectRoot/app/config/parameters.yml with these default values: parameters: database_driver: pdo_mysql database_host: 127.0.0.1 database_port: null database_name: symfony database_user: root database_password: null mailer_transport: smtp mailer_host: 127.0.0.1 mailer_user: null mailer_password: null locale: en secret: ThisTokenIsNotSoSecretChangeIt During development we change these parameters to the development database and mail servers. This file is checked into the source code repository. The problem is when we want to deploy to the production server. We are thinking about automating the deployment process by checking out the project from git and deploy it to the production server. The thing is that our project manager has to manually update these parameters after each update. The production database and mail servers parameters are confidential and only our project manager knows them. I need a way to automate this step and suggestion on where to store the production parameters until they are applied?

  • Cone of Uncertainty in classic and agile projects

    - by DigiMortal
    David Starr from Scrum.org made interesting session in TechEd Europe 2012 - Implementing Scrum Using Team Foundation Server 2012. One of interesting things for me was how Cone of Uncertainty looks like in agile projects (or how agile methodologies distort the cone we know from waterfall projects). This posting illustrates two cones – one for waterfall and one for agile world. Cone of Uncertainty Cone of Uncertainty was introduced to software development community by Steve McConnell and it visualizes how accurate are our estimates over project timeline. Here is the Cone of Uncertainty when we deal with waterfall and Big Design Up-Front (BDUF). Cone of Uncertainty. Taken from MSDN Library page Estimating. The closer we are to project end the more accurate are our estimates. When project ends we know exactly how much every task took time. As we can see then cone is wide when we usually have to give our estimates – it happens somewhere between Initial Project Concept and Requirements Complete. Don’t ask me why Initial Project Concept is the stage where some companies give their best estimates – they just do it every time and doesn’t learn a thing later. This cone is inevitable for software development and agile methodologies that try to make software world better are also able to change the cone. Cone of Uncertainty in agile projects Agile methodologies usually try to avoid BDUF, waterfalls and other things that make all our mistakes highly expensive. Of course, we are not the only ones who make mistakes – don’t also forget our dear customers. Agile methodologies take development as creational work and focus on making it better. One main trick is to focus on small and short iterations. What it means? We are estimating functionalities that are easier for us to understand and implement. Therefore our estimates are more accurate. As we move from few big iterations to many small iterations we also distort and slice Cone of Uncertainty. This is how cone looks when agile methodologies are used. Cone of Uncertainty in agile projects. We have more cones to live with but they are way smaller. I don’t have any numbers to put here because I found any but still this “chart” should give you the point: more smaller iterations cause more but way smaller cones of uncertainty. We can handle these small uncertainties because steps we take to complete small tasks are more predictable and doesn’t grow very often above our heads. One more note. Consider that both of charts given in this posting describe exactly the same phase of same project – just uncertainties are different.

  • Which stages of the requirements analysis process in mobile requirements engineering are the most challenging ones?

    - by user363295
    I'm doing a research on formulating a requirements analysis model as a stage of requirements engineering for mobile-application development by considering the limitations and the needs of it ( agility and etc.. .), what I'm trying to figure out is that which parts of this process (requirements analysis for mobile development) are the most challenging ones ( so i can focus more on) , and if there is any stage that u think I need to include or exclude (exp. some may think a quality plan may or may not be necessary and etc.) to make it more clear below is the list of few of the areas in which I can focus on ( by the way your suggestions can be anything out of the below list.) -Requirements specification -Prototyping -Requirements Prioritization -Focusing on quality functions

  • Building iPhone Interfaces for Oracle E-Business Suite

    - by Shay Shmeltzer
    Over on his blog Juan has been showing you how simple it is to develop a rich Web user interface with ADF accessing Oracle E-Business Suite data and even exposing it on an iPad. In this entry I'm starting from his sample application and I'm showing how easy it is to build an interface that will look great on an iPhone (or other mobile devices) using Oracle ADF Mobile Browser. For those of you who are just using ADF and never tried ADF Mobile Browser - you'll find that the development experience is quite familiar and similar to your normal Web application development. In the latest version of JDeveloper (11.1.2.1) which I'm usingin this demo we have a built-in skin that will give your application the native iOS look and feel. In the demo I achieve this by setting the styleclass of a tr:panelHeader component to af_m_toolbar to get this. For more on this styling read the doc. Check out this quick demo:
