          Re:   Compuware Corporation
                Form 10-K for the fiscal year ended March 31, 2007
                File No. 000-20900

Dear Ms. Collins:

On behalf of Compuware Corporation, a Michigan corporation (the "Company" or
"Compuware"), I am responding to the Staff's comment letter dated November 16,
2007 with respect to Compuware's Form 10-K for the fiscal year ended March 31,
2007. I have set forth below each question contained in the Staff's comment
letter, followed by our response thereto.

FORM 10-K FOR THE FISCAL YEAR ENDED MARCH 31, 2007

CONSOLIDATED STATEMENTS OF OPERATIONS, PAGE 44
- ----------------------------------------------

1.  WE NOTE YOUR RESPONSE TO COMMENT 2 IN YOUR LETTER DATED JULY 20, 2007
    REGARDING INCOME STATEMENT PRESENTATION FOR ARRANGEMENTS THAT INCLUDE
    SOFTWARE AND PROFESSIONAL SERVICES WHERE YOU HAVE DETERMINED THAT VSOE OF
    FAIR VALUE FOR THE PROFESSIONAL SERVICES DOES NOT EXIST. YOUR RESPONSE
    INDICATES THAT THE COMPANY ALLOCATES REVENUES TO PROFESSIONAL SERVICES BASED
    ON HOURLY RATES AND THE REMAINDER GOES TO LICENSE REVENUE. IN YOUR CURRENT
    RESPONSE TO OUR PRIOR COMMENT 3 TO OUR LETTER DATED AUGUST 16, 2007, THE
    COMPANY NOW ACKNOWLEDGES THAT IN ADDITION TO THE LICENSE AND PROFESSIONAL
    SERVICES ELEMENT, THESE CONTRACTS ALSO INCLUDE PCS. IT IS NOT CLEAR FROM
    YOUR ORIGINAL RESPONSE, HOWEVER, WHERE OR HOW YOU ALLOCATE THE REVENUES FOR
    SUCH ARRANGEMENTS TO EACH ELEMENT (LICENSE, PROFESSIONAL SERVICES AND PCS).

    As indicated in our previous letters, we occasionally enter into software
    arrangements combined with professional services where it is not possible to
    reasonably estimate the hours to complete the professional services portion
    of the arrangement. While the contracts governing these arrangements
    typically provide for time and materials billing, we had a history of only
    charging the estimated fee provided to the customer (i.e. in substance,
    these are fixed fee arrangements). In situations where we can not reasonably
    estimate the professional services hours, we have concluded that VSOE of




    fair value of the professional services does not exist. Therefore, as
    mentioned in our previous response, we can not separate the various elements
    into separate units of accounting. Accordingly, we recognize all arrangement
    consideration as a single unit of accounting. We do not recognize any
    revenue up-front for such arrangements. All revenue is recognized over time.

    Even though we recognize revenues related to these arrangements as a single
    unit of accounting, for presentation purposes we allocate revenues to the
    various elements (license, professional services and PCS) that comprise the
    single unit of accounting. The revenue recognizable in each reporting period
    is allocated between the various elements as follows:

       o  We first allocate a portion of the revenue that is recognizable in the
          period to the undelivered elements (professional services and PCS) for
          income statements classification purposes as follows:

             o  Since we have established VSOE of fair value for professional
                services on an hourly or daily rate basis, we use this VSOE of
                fair value for professional services (hourly or daily rates when
                sold separately) multiplied by the actual hours incurred during
                the period as our best estimate of fair value for classifying
                revenue as professional services.

             o  Since we have established VSOE of fair value for PCS an amount
                equal to the VSOE of fair value of PCS is classified as PCS
                revenues.

       o  The remaining portion of the revenue that is recognizable during the
          period is classified as license revenue.


2   WE NOTE YOUR RESPONSE TO OUR PRIOR COMMENT 2 WHERE YOU EXPLAIN WHY YOU ARE
    UNABLE TO DETERMINE VSOE OF PCS FOR ARRANGEMENTS THAT INCLUDE PRODUCTS WITH
    DIFFERENCE PCS RATES. IN YOUR RESPONSE TO COMMENT 2 IN YOUR LETTER DATED
    JULY 20, 2007, THE COMPANY PROVIDED AN EXAMPLE OF THE CALCULATIONS USED TO
    ALLOCATE REVENUE FROM THESE ARRANGEMENTS AMONGST PRODUCT AND SERVICES FOR
    INCOME STATEMENT PRESENTATION PURPOSES. WHILE WE NOTE THAT THE COMPANY
    ALLOCATES ANY DISCOUNT PERCENTAGE PROPORTIONATELY TO THE LICENSE FEE LIST
    PRICES AND THEN APPLIES THE APPLICABLE PCS RATES, IT APPEARS, THAT THE
    DISCOUNT FROM THE LIST PRICE IS CALCULATED AS A PERCENTAGE OF THE LICENSE
    FEE LIST PRICE TO THE TOTAL CONTRACT PRICE AND DOES NOT FACTOR IN THE PCS
    FEES IN DETERMINING SUCH DISCOUNT. PLEASE CONFIRM. IF THIS IS TRUE THEN IT
    WOULD SEEM THAT THE PROPER CALCULATIONS WOULD BE TO FIRST CALCULATE THE PCS
    APPLICABLE TO THE LIST PRICE OF EACH LICENSE TO COME UP WITH A TOTAL GROSS
    CONTRACT VALUE AND THEN DETERMINE THE DISCOUNT FROM THE TOTAL GROSS VALUE
    (LICENSE AND PCS INCLUDED). THE DISCOUNT RATE WOULD THEN BE APPLIED THE LIST
    PRICE OF THE LICENSES AND THEN THE PCS RATES WOULD BE APPLIED TO THE
    DISCOUNTED LIST PRICE. IF YOU AGREE WITH THE STAFF'S CALCULATIONS, THEN
    PLEASE EXPLAIN HOW YOU CONSIDERED INCLUDING THE PCS FEES IN YOUR
    CALCULATIONS OR TELL US IF YOU PLAN TO REVISE YOUR CALCULATIONS ACCORDINGLY.

    We believe our current approach is consistent with the Staff's calculations.




    Our VSOE of fair value for PCS is based on a fixed percentage of the gross
    license fee. The gross license fee represents what a customer is charged for
    the license and the first year of PCS, net of any discounts. Our definition
    of the gross license fee is the same as what you have characterized as gross
    contract value less any discounts. As such, the discount percentage in our
    calculations does factor in the PCS fees in the arrangement.

    To illustrate, please refer to the example in our letter dated September 19,
    2007 and repeated below:

    Assume we license Product A (list price $390) and Product B (list price
    $910) to a customer who agrees to pay us $1,000 for the perpetual license
    rights to both products and one year of PCS on both products. The
    transaction represents a 23.08% discount from our list price of $1,300.
    Assume the VSOE of fair value of PCS on Products A and B are 25 percent and
    18 percent of gross license fees, respectively.

    In your comment you indicate that "...the proper calculations would be to
    first calculate the PCS applicable to the list price of each license to come
    up with a total gross contract value and then determine the discount from
    the total gross value (license and PCS included)".

    Our methodology is consistent with this approach. The list prices of $390
    for Product A and $910 for Product B relates to both the license fee and the
    first year of PCS. Therefore the gross contract value (before any discounts)
    is $1,300. The amount charged the customer is $1,000 for both the license
    and first year PCS rights, representing a discount of 23.08% (the same as in
    our example).

    Your comment further indicates that "The discount rate would then be applied
    to the list price of the licenses and then the PCS rates would be applied to
    the discounted list price."

    Consistent with your comment, once we have determined the discount rate we
    would then apply it against the list price of licenses (which list price
    includes the first year of PCS) and then the PCS rates would be applied to
    the discounted list price.

We acknowledge that we are responsible for the adequacy and accuracy of the
disclosure in all Company filings. We understand that neither the staff's
comments nor changes we make to our disclosure in response to staff comments
foreclose the Commission from taking any action with respect to our filings and
that the Company may not assert staff comments as a defense in any proceedings
initiated by the Commission or any person under the federal securities laws of
the United States.

Please feel free to call me at (313) 227-7372 with any questions or if we can be
of any assistance.


Very truly yours,
