This will help ensure a more genuine testing experience. There are several types of testing that should occur during each sprint. These typically include the following:. Functional Testing - Testing to ensure the feature works as described in the requirements. Usually, a QA team will have a test plan with a list of actions and the desired app behavior.

Usability Testing - Testing to ensure the feature is user-friendly and is as intuitive as possible. Performance Testing - Your app might work perfectly, but if it takes 20 seconds to display a simple list, nobody is going to use it. Fit and Finish Testing - Just because the design phase is complete past, doesn't mean you can lock your designers in a closet. Designers should review each feature and ensure that their vision was implemented as described in the design.
This is another reason why having one agency for both design and development is so beneficial. Regression Testing - Remember that one feature from the previous sprint? Good QA teams will have a list of tests to perform at the end of each sprint, which will include tests from previous sprints.
Device-Specific Testing - There are tens of thousands of device and operating system combinations in the world. When testing, make sure you try out your app on numerous screen sizes and OS versions. User Acceptance Testing - This is testing performed by either the app owner or future app users. Remember who you are building this app for and get their feedback throughout the process. If a feature passes all the above tests, but fails this one, what use is it? As problems are discovered in this phase, reassign tasks back to developers so that the problems can be resolved and the issues closed out.
Once testing has been completed and each task is done, move on to review. At the end of each sprint talk with each of the stakeholders and determine how the sprint went. If there were difficulties, try to eliminate similar issues from future sprints. If things went well in one area, try to apply them elsewhere. No two projects are the exact same and everyone should always be advancing in their roles, so aim to improve, while you iterate.
Once review is complete, begin again with the planning phase and repeat this process until the app is done! At this point your app should be fully testable and feature complete at least for the MVP. Before you spend a sizable amount of time and money on marketing, take the time to test your app with a sample of your potential users. There are two main ways to go about this. Focus groups involve conducting an interview with a tester or group of testers who have never seen the app before and conduct an interview.
You want to understand who these testers are, how they learn about new apps, and if they use similar apps already. Try to get some background info out of them before even getting into your product. Next, let your testers begin using your app. They should not be coached during this process. Instead, let them use the app as if they had just found it in the app store. See how they use the app, and look for common frustrations.
After they are done using the app, get their feedback. Remember to not be too strongly guided by any one tester, but combine feedback and make intelligent decisions using all available feedback. In addition to, or instead of focus groups, you can do a beta launch of your app. Beta tests involve getting a group of testers to user your app in the real world. They use the app just as if it had launched, but in much smaller numbers. Often these beta testers will be power users, early adopters, and possibly your best customers.
Make sure they feel valued and respected. Give them ample opportunities to provide feedback and let them know when and how you are changing the app.
Also, beta testing is a great time to see how your app performs on various devices, locations, operating systems, and network conditions. It is imperative that you have sound crash reporting for this step. It does you no good if something goes wrong, but is not discovered and diagnosed. After these extended review periods, it is common to have a final development sprint to address any newly discovered issues. Continue beta testing during this process and ensure that your crash and issue reports are declining.
Once you have the all-clear from your testers, it is time to begin preparing for deployment. There are two main components to deploying your mobile app into the world. The first involves deploying your web server API into a production environment that is scalable. Most mobile apps require a server back-end to function.
These web servers are responsible for transferring data to and from the app. If your server is overloaded or stops working, the app will stop working. Properly configured servers are scalable to meet your current and potential user base, while not being needlessly expensive. It is not terribly difficult to scale for most mobile apps, but you want to ensure your team knows what they are doing or your app could fall apart, just when it gets popular.
Submitting your apps to the app stores is a moderately involved process. You need to make sure your apps are properly configured for release, fill out several forms for each store, submit screenshots and marketing materials, and write a description. Additionally, Apple manually reviews all apps submitted to their app store.
It is possible they will request you make changes to your app to better comply with their regulations. Often, you can discuss these changes with Apple and get them to accept your app as-is. Other times, you might have to make changes to be granted entrance.
Once your app is submitted, it will be live in Google later that day and in Apple within a few days, assuming everything goes smoothly. It would be incredibly naive to think that the mobile app development process ends when the app is shipped.
Go look at any even moderately popular apps and you will see a long history of app updates. These updates include fixes, performance improvements, changes, and new features. Thorough monitoring is essential to best understand what sort of updates are needed. Here are a few things you should be monitoring. There are numerous libraries that can be used to reliably track app crashes. These libraries include information about what the user was doing, what device they were on, and plenty of technical info that is crucial for your development team in resolving the problem.
These crashes can be viewed and triaged accordingly. Sentry and HockeyApp. Modern app analytics systems are are treasure trove of information. They can help you understand who is using your apps age, gender, location, language, etc. Some even allow you to view heat maps of your app, so you know what buttons on each screen are clicked most often. These systems provide an invaluable glimpse into how your app is being used. Use this information to best understand where to invest future efforts.
One vital metric not covered by the previous two monitoring categories is your apps technical performance, i. Any system we deploy has extensive performance monitoring in place.
Wireflows as a Deliverable for Workflows
We are able to track how many times an action occurred and how long that action took. We use this to find areas ripe for optimization. We also put alerts in place to let us know if a particular action is slower than expected, so we can quickly look to see if there are any issues.
These performance tools typically have dash-boarding, reporting, and alerting functionality included.
How to prototype users flows for mobile apps: A Justinmind guide
At this point we are less concerned with how individual screens within the app look and more interested with how the user broadly interacts with the application and navigates between its various sections. There are two major reasons for mapping out an application in this way. Now is the time to ensure all the features are accounted for. Second, we must try to cover every possible outcome and cater for unforeseen circumstances.
Take a simple login screen.
Flow Chart App
Mapping the flow from entering the username, password and pressing the login button to a user successfully being logged in is only the start of it. What happens if either of the fields is invalid? How specific should the error message be? Will it simply alert the user to an error with the inputted data or will it specify which element was incorrect? Do we also need to account for other possibilities such as lack of data connectivity? The process flow diagram, as shown in Figure 1, details what happens between actions.
Is the app storing data locally? At what point are connections made to online services? The combination of all of these will not only ensure the application will function properly but also will provide clear guidance to the developer writing the code. It is sensible to keep the process flow diagram updated as changes are made during development. An up-do-date flow diagram will also be invaluable when testing an application and can be used to double check that each part of the application has been tested.
However, as long as the flow diagram is clearly labeled these details are unimportant. There are also perfectly good web-based solutions like Gliffy www. It is possible to create flow diagrams within Microsoft Office suite Word or Excel although these tools are limited and major edits are more difficult. A basic flow diagram details the first few stages of a connected mobile application. For very simple projects the flow diagram may cover most of the user interface of the application, but more commonly it will mainly detail the more complex behind-the-scenes processes.
The user-facing screens will only be touched upon. A good way to move on to the next stage is via a hub and spoke diagram. Hagan Rivers, a design consultant, calls these diagrams Application Maps. She uses them to highlight the main hubs of activity in an application. In her blog post http: An example of a hub and spoke style application map.
If your mobile app is very complicated it might not be immediately clear where to start with the user interface design. A hub and spoke style application map is a good way of revealing how the pieces of your app fit together. In these situations, including the wireframe image may be more of a burden than a benefit. It just depends on your audience. My last tip is this: Use Lucidchart.
Lucidchart will add value to your user flows in a number of ways. First, Lucidchart is a diagramming app, but it also supports wireframes. When I am building user flows, I can cannibalize the wireframe shape libraries to mock up our UI and easily connect it to the logic of the app. Second, Lucidchart makes collaboration seamless. When I was trying to document the login flow of our existing application, I had to rely on the expertise of many individuals to build an accurate depiction. When I had questions about a process, it was easy for me to tag an expert in a comment on a specific shape and ask a question.
When the documentation was finished, I could quickly share the diagram with the entire mobile team so they could refer to it during development. Third, Lucidchart serves as a single source of truth from the moment you start a project until the day your code is released. I never had to worry about opening Visio, exporting my documentation as a PDF, attaching it to an email, and then tracking down outdated versions any time an update was made.
I always knew that my team had access to the most recent diagram because it was always saved and updated in the cloud. Finally, Lucidchart allows you to attach diagrams to JIRA and Confluence for reference during troubleshooting and development. The best part is that, as you update your diagrams in Lucidchart, they are updated where you have embedded them as well. Learning which information to share in a user flow diagram may take some practice, but you can start diagramming in Lucidchart right now. All you have to do is register.
