You should not begin your case study letter with your thesis statement; this must come after. The thesis is what you will be promoting or arguing in your letter. You should begin with some statements that you think will be interesting to your readers or the committee reviewing your paper.
“I would like to express my strong opinion that Dr. X is an excellent teacher. His teaching style has brought up many graduate students that have achieved highly successful careers in industry, government, law, medicine, or academe. I would like to suggest that he receive all the recognition for his excellent academic achievements that is due to him.” This shows the committee that you are worthy of recognition and respect, and your name should be on that list.
“My name is David and I am the president of XYZ Company. If you would like to hire me, please send me a formal application so that I may set up an interview with you.” You might want to let the faculty know that you were a former member of XYZ Company and how well you did there. For the interview, you would want to highlight some of your skills and experiences that are relevant to the position.
“I would like to thank the faculty for their consideration in accepting my application for a faculty position at XYZ Company. This is a great honor and I will definitely be using this letter as a resume. I want to assure the members of XYZ Company that they can trust me completely. I believe in self-confidence and independence. This is exactly what I bring to the company.” This is a strong purpose of a letter and it makes you sound confident and capable.
“I would like to thank the XYZ Company for considering me for a position in their industry. It was a great honor to have your acceptance of my application. Thank you again for taking the time to read the letter that I wrote in response to their request for a case study letter. I look forward to working with you in order to achieve our shared vision.” This is a positive statement and a clear intent of your intentions with your letter.
“I would like to state in my letter that I have successfully implemented and managed a variety of changes within the operations of XYZ Company. This company has allowed me to grow and be responsible for developing and implementing various important and complex projects. This past responsibility has allowed me to take on leadership roles and be an asset to the success of XYZ Company and its partners.” This statement shows that you have achieved leadership roles within your company and you have managed projects before. This case study letter shows your experience and your capabilities.
Your letter should be an extension of yourself in that it shows how you can contribute to the success of the company. “The purpose of this letter is to express my desire to work with XYZ Company and to make this organization a better place. I believe that XYZ Company would be best served by someone with the characteristics described above. If you are looking for a career change or advancement, my years of experience with XYZ Companies make me an ideal candidate.” This is a strong purpose of case study letters.
