User Story is the place PO gives his ideas about features so that developers are able to know what requirements are. Acceptance tests are these show the most valuable things of the features represented by some specific cases. Usually PO defines them, but not always. Therefore, refining existing acceptance tests – even defining new ones that cover all features of the User Story must be a worth task. Acceptance test with Given When Then pattern If we understand what we are going to do, we can complete it by 50% I have worked with some members those just start implementing the features one by one and from top to down of the User Story description. Be honest, I am the one used to be. What a risky approach! Because it might meet a case that is very easy to miss requirements or needs to re-work after finding any misunderstood things. I have also worked with some members those accept spending a long time to clarify the User Story. Reading carefully of whole User Story by defining

Have you ever got bored with the Retrospective meeting? I have, sometime. Most of the times, this meeting just goes traditionally by answering three questions: "What good things have we done? What bad things have we done? And, what actions should we improve?" Ever and ever again! My team found a way to make it a little bit more exciting. The idea is that each member - not only our Scrum Master - will become a host. If a meeting is hosted by a memeber, the next meeting will be hold by another one. Yeah, I used "Sailboat" pattern in my turn. So, I just want to share with you guys how it was. I started the meeting by telling a short story that I hoped everyone in my team could recall the meaning behind of Retrospective meetings: There is a group of people trying pick up trash in a park. At the first look, the park seem not to have a lot of trash because they are spread out all over the place. However, these people continuously found trash when they sta

This article is available at blog.scrum.org , here I just quote my favorite points and give my comment at the end of this post. Ken Schwaber and Jeff Sutherland, the creators of Scrum delivered a webinar on their latest update to the Scrum Guide .  The update was a simple one, adding the 5 values of Scrum to the Guide: These values sound easy? Well, there are many misunderstandings and common problems when applying these values. Here are some example: Value Misunderstanding Getting the value right Commitment Committing to something that you don’t understand because you are told to by your boss. Committing yourself to the team and Sprint Goal. Focus Focusing on keeping the customer happy Being focused on the sprint and its goal. Openness Telling everyone everything about all your work Highlighting when you have challenges and problems that are stopping you from success Respect Thinking you are helping the team by being a hero Helping people t

So far, Primefaces has used image sprites for displaying the sort icons. This leads to a problem if we want to make a different style for these icons; for example, I would make the icon "arrow up" more blurry at the first time the table loading because I want to highlight the icon "arrow down". I found a way that I can replace these icons with Font Awesome icons. We will use "CSS Pseudo-classes" to achieve it. The hardest thing here is that we should handle displaying icons in different cases. There is a case both "arrow up" and "arrow down" showing and other case is only one of these icons is shown. .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s { background-image: none; margin-left: 5px; font-size: 1.1666em; position: relative; } .ui-sortable-column-icon.ui-icon.ui-icon-carat-2-n-s:not(.ui-icon-triangle-1-s)::before { content: "\f106"; font-family: "FontAwesome"; position:

"Names are everywhere in software". "The hardest thing about choosing good names is that it requires good descriptive skills"[1] . In my previous post, I emphasized that we should take care our code , so now let's start with naming.

Have you ever thought that we won't need to code anymore because programs might be generated from specification? The answer can be yes or no; there is still arguing about it. The programming language is more and more closed to the requirements. The starting is from a very low level as Assembly to a very high level like Python. However, it doesn't make much sense when saying that we will eliminate coding. For me, we currently still need to express our ideas in exact words that tells the machine what we want. Otherwise, I hope in the future the machine is intelligent enough to understand our requirements directly from our words. ;) Take a look at the famous quote of Robert C.Martin about what I mentioned above: "Remember that code is really the language in which we ultimately express the requirements. We may create languages that are closer to the requirements. We may create tools that help us parse and assemble those requirements into formal structures. But we wi
