Does Agile Allow for Effective Software Testing?

My experience with the Agile process has been geared to manual and automated testing.  The software developers spend 3 sprint periods developing new features and fixing defects.  At the end of the 3 sprints the developers deliver a new product with an outline of new features and fixed defects.  This gives the testing team 2 sprints to test the software and report any new defects or report if existing defects still exist.

For this process to work correctly the developers must be able to deliver working software by the end of the period and when the testers receive the software they must have all resources needed in a properly operational state.  In my experience it has been very difficult for developers to release working software on time which limits the time available for testers.

Once the testers receive the software there are sometimes a shortage of resource to do the proper testing.  Many times this is because the testing resources are expensive.  There often are technical or mechanical issues that make some testing resources unavailable. 

After the testing has been done there are new defects that must be planned into the next few sprints.  When the software has many new defects this limits the amount of new features that the developers can implement within the next few sprints.  With an unknown amount of defects after each testing sprint it makes it hard to plan new features.

In summary I believe that to create an environment that is conducive to proper testing the organization must have very good procedures in place to ensure that deadlines are met and resources are available when needed. Again, this is another example of how it takes an organization some trial and error to properly use the Agile development process.

The Transition to Responsive Design

Since being hired on to an internship working with and designing websites, I have learned a great deal about responsive design and it's advantages.  I came into the internship not knowing a thing about responsive design and knowing limited CSS3 and HTML5.  After completing a few tutorials, I caught on really quick.  My first task was to re-create an already created website.  This took me awhile to get my homepage set up the way they wanted it and looked the way they wanted it.  After finishing with all the HTML5 and CSS I thought I was done.  The website looked good.

I was then introduced to responsive design.  Apparently, my website was just at it's beginning.  I had created the homepage and all the subpages and it looked great!  My boss then asked how it looked when I decreased the window size.  The website then started breaking down and looking cluttered.  The formatting did not look good at all.  I was then introduced to media queries.  These are a savior when it comes to responsive design.  It allows you to design how the website will look at different window sizes.  This took a great deal of time to get everything organized to where it looks good at any window size, but when it was done I felt very accomplished.  I realized I create an entire website to not only work on a desktop computer, but to work on a mobile phone.  I searched the website on my phone and it looked great!

This really made me feel very good about myself when I finished the website.  I came in not knowing anything about responsive design.  I was then able to think intuitively and learn how to use media queries.  Now my website looks great no matter what the screen size.  In my management class we talked about intrinsic and extrinsic motivation and I didn't really believe that people get more motivated from intrinsic motivation.  After this project, I fully endorse that intrinsic motivation is the best way to go.  The feeling of accomplishment is very underrated.  I will continue my internship and hopefully learn even more about website design!

“Please turn off and put away all electronic devices” statement is no more

Last Thursday, the U.S. Department of Transportation’s Federal Aviation Administration (FAA) announced that airline passengers will now be able to use portable electronic devices at any time of a flight, no matter the altitude.  This is in contrast to the policy that was in place up until now, where passengers were not allowed to use electronic devices any time the plane was below 10,000 feet. 

The previous rules governing electronic use in flight were based on the assumption that radio signals produced by electronic devices could interfere with an airplane’s radar, communications, and other systems during takeoff and landing.  This logic was proven faulty last year when a panel created by the FAA determined the majority of commercial airplanes are able to handle radio interference signals without a problem.

Even though the restrictions are fewer, the ruling should not be taken as a completely free pass on electronics.  For one, the use of cell phones for voice communication is still banned.  Perhaps of most significance is the fact that devices capable of data transfer or internet access besides Wi-Fi must still be in airplane mode throughout the duration of the flight.  These restrictions, when in combination with the new permissions for electronic devices, make the lives of flight attendants a little more difficult.  In addition, the new rules will make it more important for flight attendants to make sure all travelers are attentive during the safety briefing portion of flights.

Despite all this, the lift on the electronic devices ban is being met by praise across the board.  Just a few hours after the announcement, Delta Air Lines and JetBlue both filed plans with the FAA to allow the extra usage time on their flights.  They will be given approval once the FAA makes sure the air lines are following their implementation guidelines.   Members of travel and electronics industries have been especially appreciative of the decision.  U.S. Travel Association president and CEO Roger Dow voiced his approval in a prepared statement, which included “What’s good for the traveler is good for travel-related businesses and our economy.”   From the general consumer and traveler, the ruling is expected to be met with positive feedback.  I know the extra time will not be much, but I am looking forward to it myself.

Turning Big Data into Actions

‘Big Data’ is a fairly new buzz word in the IT world.  In this day and age there is a wealth of data available and many resources available to store all of this data.  The problem with raw data is that it does not help with decision making.  People must know how to manipulate and use the data in order to make it useful.  On Forbes website I read an interesting article called “Four Step To Turn Big Data Into Action”.  Click here for a link to the website.  According to the article there are four steps to turn big data into something useful and they are as follows:

• Decide what to produce
• Source the raw materials
• Produce insight with speed
• Deliver the goods and act

This article takes the view of a factory where insights are products, data is the raw material and the front-line operators are the consumers of the product.

In the first step the article states that it is important to have a clear understanding of what you want to achieve and what questions need to be answered.  The questions that answer the largest economic opportunities should be the highest priority.

In the second step the article emphasizes that it’s important to start with the best data that is immediately available.  This data set can often times be small and not necessarily the best data set but this gives a good start with immediate feedback.  Then over time it is important to start adding other data sets to it and begin getting a better insight.

In the third step the article emphasizes speed.  Early on the ‘insight factory’ will not produce perfect information but it’s important to have rapid bursts or output.  The product will get better with time but it’s important to have the speed early on.

Finally in the last step the article states that the information that is available now should be used now to inform specific actions.  This means put this information into action now and see the actual results instead of waiting for more data or other options.  In this step there will also need to be acceptance from managers which will take time.  It is important to remember that this factory idea is a cultural change that will need to evolve over time and should not be one large change.

Is change a good thing? You be the judge.

Last August, Microsoft released their latest operating system, Windows 8.  It was met with highly mixed reviews.  Some complimented the sleek new Metro design and increase in speed compared to its predecessor Windows 7.  However, many were annoyed by its tablet-centric design, which included a tiled start screen, and lack of common features that existed in past OS versions, most noticeably the start button.  On Thursday, Microsoft released their attempt to respond to some of these concerns:  Windows 8.1.

With Windows 8.1, Microsoft has added a number of features that may ease the transition between 7 and 8 for newcomers.  The start button has made its return, although using it brings you to the still unfamiliar tiled application screen for actions.   You can also choose to boot directly to the desktop rather than going through the tile interface each time.  The level of customizability of the user environment has been increased, with more colors and size options for applications.  Microsoft has also increased the integration of SkyDrive.  In Windows 8, users had access to their cloud-based files only through online access, while they could add offline capabilities by installing a SkyDrive application.  With 8.1, the offline ability is integrated from the get-go.  Additionally, SkyDrive is built into the new “Smart Search” function, meaning users’ SkyDrive files show up just as normal files do upon a search.  The app store has also substantially increased its content, growing from around 10,000 apps at the launch of Windows 8 to more than 110,000 today. Finally, Microsoft answered one of the biggest complaints about Windows 8, which was the limitation in multitasking due to the restriction of app sizes to either the entire screen or 25 percent and 75 percent.  Now, you can display up to four apps side by side, or just do the traditional 50/50 split that many requested.  Additionally, you can alter sizes at will, without preset percentages.

How will these changes be received by the community?  While the improvements made may satisfy the early adopters of Windows 8, whether it will attract users of Windows 7 to upgrade is an entirely different story.  The bottom line is that the stigma of Windows 8 as being an OS built for mobile devices, not desktops, will most likely persist.  Microsoft may have to wait for their Metro system to be more readily accepted by an increasingly mobile-centric technology environment before they see a large movement to Windows 8.

Issues with newly formed SCRUM teams

Previously I had mentioned the Agile Software Development Methodologies, specifically the Scrum methodology.  The Scrum method is one of the most popular methods for many reasons but there are also some issues that come along with this methodology.  Just as a refresher Scrum is a framework of teams with about 2-12 people and they all have 1 of 3 different types of roles.  There are daily, sprint and PSI meetings that the teams must all attend.  Overall this framework is very team oriented, self-managed and fast-paced.

With experience in the Scrum framework there are a few noticeable issues with it.  From my experience the meetings become overwhelming.  As many people in the professional world know, meetings are not fun.  This means if the meetings are not productive people will begin to not show up or organizers will cancel them if other things come up.  I notice the lack of involvement in these meetings over time.  If the team was behind schedule or a major defect was found than all meetings were put on the back burner or just ignored.  This hindered the Agile process immensely.  The daily stand-ups were usually attended regularly but the other meetings that were focused on team building and not product oriented tended to be skipped by team members.

Another issue that I saw was the trap of such short time frames.  During an 8 week PSI if there was a 2 week period where unexpected issues came up then the team would never be able to make up time and meet their week 8 deadline.  In this situation if working software is to be delivered at the end of week 8 and the team of testers are waiting for it but it never arrives there are big problems.  Everyone’s plans for the next 8 week session must be changed which ultimately costs a lot of money, pushes back deadlines and creates stress.

These are just a couple of the main issues that I have seen with the Scrum framework.  These teams are also very new to the Agile process which is part of the reason why the problems exist.  It will just be a matter of time if organizations see results with these methodologies or not.
