The rise of mobile smartphones and its usage of mobile applications made the human life more productive and boosted several activities in everyday routine jobs and business areas. In another side now a day, most of the business and personal applications transferred to the mobile apps. The one hand mobile application providing more features than traditional desktop applicationas and proving endless opportunities for new ventures. Day to day mobile application are becoming a part of several model device with different mobile operating system such as Android, iOS, Windows, BlackBerry, Symbian, etc. and it becomes challenging to development and quality assurance teams to verify and validate mobile app that works on end-user mobile with no error. With growing technology, mobile application development companies adopted new tools and work in different development approaches such as waterfall, agile, prototyping [1], [2], [3] but still, challenges are same for the quality assurance team to test the application and make application error free in the dedicated short time. The testing mobile application becomes more challenging due to the growing number of devices by the different vendor and test on all possible devices sometimes impossible for the quality assurance team. The mobile application testing team most of the time face challenges related to the usability, interrupts, poor connections, device settings with functional and non-functional testing issues. In such situation, test planning and building more proper test strategy to cover all aspects will lead to making application error free. From many years, lean canvas boards are used for the developing business plans, strategy and for risk analysis. This paper is focuses on the re-design and develop lean canvas design using lean principles to use it for the mobile application testing process and it can affect precisely on app testing quality, resource, cost and time.
