Recently i have posted a couple of replys on the Microsoft Software Test forum – http://msdn2.microsoft.com/en-us/testing/default.aspx – click the link entitled Software Testing Discussion Forum.
There are a couple of posts on Test Strategy and Test Plans and what they are. Quite often the two terms are interchangeable and used indiscriminately. A Test Strategy (according to ISTQB) is the document that describes the methods of testing or the how. Whether this document is pitched at an enterprise level or a project level is open to discussion but essentially the Strategy is projecting ideas over a longer period of time.
The Oxford Dictionary defines Strategy as “… a plan designed to achieve a particular long-term aim” and as such looks at the ‘bigger’ picture.
A Test Plan describes the ‘How’ at a lower level. IEEE 829 (on which there is much debate on the revision currently being voted on) introduces the structure of should be incorporated in the plan. It is comparable to tactics which again according the Oxford Dictionary is “…an action or strategy planned to achieve a specific end.”
Whether you use either or both terms or documents is up to you. As testers we sometimes become involved in paper wars and become document heavy at the expense of efficiency and effectiveness. Whatever process you follow the key for any test document is effective communication.
Bj Rollison – a Test Architect at Microsoft (http://blogs.msdn.com/imtesty/about.aspx) sums up what happens if we stop thinking about how and what we use these documents for…”The only testers who stop thinking critically about tools and the application of tools we can use in the appropriate context are testers who have a limited understanding of the overall responsibility of testing, and know even less about the tools they are tyring to use.”
Great quote – i totally agree. Whether its a Test Strategy or Test Plan, it is a tool whose purpose is to serve us and guide us in our testing activities.
If you are responsible for producing said documents, please be critcial in your thinking and look at the best way to communicate to all those involved in your sphere!
The 2006 NBA season the Phoenix Suns Strategy vs. the LA Lakers was “…Phoenix’s strategy against the Lakers this season has been to contain everyone besides Kobe Bryant, and it’s worked. Bryant had 39 points in the first meeting and 37 in the second, but no other Lakers player scored more than 17 in the two games and the Suns simply outscored Los Angeles, averaging 114 points.” – Yahoo Sports.
There is your Strategy, the plan is how each Sun player played defense against their man.
Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat.– Sun Tzu
