   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 August 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 PRIOR COMMENT 2 AND THE VARIOUS METHODS USED TO
     ALLOCATE REVENUE AMONGST PRODUCTS AND SERVICES FOR INCOME STATEMENT
     PRESENTATION PURPOSES WHEN GAAP DOES NOT ALLOW SUCH ALLOCATION FOR REVENUE
     RECOGNITION PURPOSES. WITH REGARDS TO SUCH INFORMATION, WE HAVE THE
     FOLLOWING ADDITIONAL COMMENTS:

          -    WHERE YOU SEPARATE PCS FOR TERM LICENSES BASED ON VSOE OF PCS AS
               ESTABLISHED FOR YOUR PERPETUAL LICENSES, PLEASE TELL US WHETHER
               THESE ALLOCATIONS ARE FOR THE SAME PRODUCT, WHICH MAY BE SOLD AS
               EITHER A PERPETUAL OR TERM LICENSE. IF THE PRODUCTS DIFFER, THEN
               PLEASE EXPLAIN HOW YOU DETERMINED THAT VSOE OF PCS FOR ONE
               PRODUCT CAN BE USED AS EVIDENCE OF VSOE OF PCS FOR ANOTHER
               PRODUCT EVEN IF ONLY FOR PRESENTATION PURPOSES.

               These allocations are for the same product which may be sold as
               either a perpetual or term license.

          -    FOR ARRANGEMENTS THAT INCLUDE SOFTWARE AND PROFESSIONAL SERVICES
               WHERE YOU HAVE DETERMINED THAT VSOE OF FAIR VALUE FOR THE
               PROFESSIONAL SERVICES



               DOES NOT EXIST, PLEASE EXPLAIN HOW THE SERVICES PROVIDED UNDER
               THESE ARRANGEMENTS ARE SIMILAR TO THE SERVICES PROVIDED UNDER
               ARRANGEMENTS WHERE YOU WERE ABLE TO ESTIMATE THE NUMBER OF HOURS
               TO COMPLETE AND ACCORDINGLY WHERE YOU WERE ABLE TO ESTABLISH
               VSOE. IN THIS REGARD, DESCRIBE THE NATURE OF THE SERVICES
               PROVIDED IN BOTH ARRANGEMENTS. EXPLAIN, IN DETAIL, THE ACTIVITIES
               PERFORMED FOR EACH TYPE OF ARRANGEMENT THAT DISTINGUISHES THEM
               SUCH THAT ONE RESULTS IN ARRANGEMENT WHERE YOU ARE ABLE TO
               REASONABLY ESTIMATE THE NUMBER OF HOURS TO COMPLETE SUCH SERVICES
               AND THE OTHER RESULTS IN ARRANGEMENTS WHERE YOU CANNOT.

               Most of our professional services are offered separately with no
               software or related PCS. However in some cases we do offer
               software with PCS and professional services. In these
               arrangements, the professional services provided are for
               implementation and training related to the software purchased;
               such as, implementation planning, loading of software, training
               of customer personnel, data conversion, running test data and
               assisting in the development and documentation of procedures.

               The general nature of our implementation and training services is
               the same for all of our software products: we install and
               configure the software and provide training to the customer on
               how to use it. However, the scope of the projects may differ
               based upon the use of each software product and customer
               preferences. To date none of our implementation and training
               services have involved significant production, modification or
               customization of the software. As further evidence that these
               professional services do not involve significant production,
               modification or customization of the software, we have third
               party providers that provide these services for some customer
               arrangements.

               We have VSOE for implementation and training services for the
               majority of our license arrangements. The implementation and
               training services are generally short term and for a specified
               number of days (e.g. 5-20 days). However, there are a limited
               number of arrangements,isolated to one of our software products,
               where we determined, effective October 1, 2005, that VSOE of fair
               value for the professional services does not exist. The
               professional services provided, while still implementation and
               training tend to be longer term (generally delivered within a
               year), and typically provide for billing as hours are worked,
               based on hourly or daily rates, where the total amount or number
               of days are not specified in the arrangement. In these
               arrangements, we had not established a history of accurately
               estimating how many hours/days we will spend to complete these
               projects. While the contracts governing these arrangements
               typically provide for time and materials billing, we have had
               several instances where we only charged the estimated fees
               provided to the customer (i.e. in substance, these were fixed fee
               arrangements).



               The reason we are unable to estimate total hours to deliver these
               projects is because our implementation of these services are
               dependent upon customer preferences that involve customer
               business processes. When customer business processes are
               involved, our ability to lead the customer to an efficient
               implementation may impact the hours to deliver the project.
               Delays and changes to scope based on changing customer
               preferences as they learn more about their business processes
               have limited our ability to deliver implementations within a
               defined number of hours, not the nature of the implementation and
               training services.

NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

REVENUE RECOGNITION, PAGE 47

2.   YOUR RESPONSE TO PRIOR COMMENT NUMBER 2 DESCRIBES ARRANGEMENTS THAT INCLUDE
     A PRODUCT WHICH HAS A DIFFERENT VSOE OF FAIR VALUE FOR PCS THAN YOUR OTHER
     PRODUCTS. IT IS UNCLEAR TO US WHY YOU ARE UNABLE TO ESTABLISH VSOE OF THE
     PCS FOR THESE PRODUCTS WHEN THEY ARE BUNDLED WITH OTHER PRODUCTS. PLEASE
     DESCRIBE THESE ARRANGEMENTS IN GREATER DETAIL, EXPLAIN WHY VSOE IS NOT
     ESTABLISHED FOR PCS FOR THIS PRODUCT AND REFER TO THE AUTHORITATIVE
     GUIDANCE YOU RELIED UPON WHEN DETERMINING YOUR ACCOUNTING.

     We recognize revenue using the residual method as described in paragraph 12
     of SOP 97-2 (as amended by SOP 98-9) under which the fair value, based on
     VSOE, of undelivered elements are deferred and the remaining consideration
     is allocated to the license portion and is recognized as revenue upon
     delivery. Our VSOE of fair value for PCS is based on a fixed percentage
     (currently 18% of the gross license fee, which represents the list price
     net of discounts but includes PCS fees) for all of our products except one
     particular product for which VSOE of fair value of PCS is a higher
     percentage of the gross license fee (currently 25% of the gross license
     fee). In situations where this product is licensed with other products, the
     arrangement fee should be allocated between the products for which VSOE of
     fair value of PCS is 18 percent and the product for which VSOE of fair
     value of PCS is 25 percent to determine the amount of PCS revenue to defer.
     Since we do not have VSOE of fair value for the license fee portion of any
     of our software products because we always sell our products with PCS we do
     not have the ability to allocate the gross license fee between the various
     software products. We don't think it is allowable, for purposes of revenue
     recognition, to allocate based on the list price or stated arrangement
     price as such amounts do not represent VSOE of fair value in accordance
     with paragraph 10 of SOP 97-2. The following example illustrates an
     arrangement in which we are not able to establish the VSOE of fair value of
     the PCS element in the arrangement.

     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 order to determine the VSOE of fair value for PCS, the arrangement fee
     of $1,000 should be first allocated between products A and B. Then the
     appropriate VSOE of fair value rates (i.e. 25 percent for product A and 18
     percent for product B) should be applied to the amount allocated to each
     product. Since we do not have VSOE of fair value for the license fees for
     our software products we do not have an objectively verifiable basis for
     allocating the total arrangement fee between the various software products.
     Accordingly, we concluded that we can not establish VSOE of fair value of
     PCS for arrangements that include our product that has a higher VSOE rate
     for PCS.

3.   YOUR RESPONSE TO PRIOR COMMENT NUMBER 2 INDICATES THAT WHEN YOU ARE UNABLE
     TO ESTABLISH VSOE OF PROFESSIONAL SERVICES, REVENUE FROM THE ARRANGEMENT IS
     RECOGNIZED RATABLY OVER THE SERVICE PERIOD. PLEASE INDICATE WHETHER THESE
     SERVICES ARE THE ONLY UNDELIVERED ELEMENT OR TELL US WHETHER SUCH
     ARRANGEMENTS INCLUDE OTHER SERVICES (I.E. PCS). IF THESE ARRANGEMENTS
     INCLUDE OTHER UNDELIVERED ELEMENTS, THEN PLEASE EXPLAIN HOW YOUR POLICY
     COMPLIES WITH PARAGRAPH 12 OF SOP 97-2. ALSO, CONSIDERING YOU ARE UNABLE TO
     REASONABLY ESTIMATE THE NUMBER OF HOURS REQUIRED TO COMPLETE THE
     PROFESSIONAL SERVICES IN THESE ARRANGEMENTS, TELL US HOW YOU DETERMINE THE
     ESTIMATED SERVICE PERIOD OVER WHICH TO RECOGNIZE REVENUE.

     For transactions we are unable to establish VSOE of professional services,
     we have both professional services and PCS as undelivered elements in the
     arrangement (these type of arrangements are described in more detail in the
     response to question number one, above). These arrangements which include
     both products and professional services and where we are unable to
     establish VSOE of professional services, relate to one of our product
     offerings, and are an insignificant percentage of our business. In FY08
     (April - June), FY07 and FY06 (October - March), we recognized
     approximately $1.4, $4.6 and $1.0 million in license fees, $0.4, $1.0 and
     $0.1 million in maintenance fees and $0.6, $4.0 and $0.7 million in
     professional services fees, respectively, related to such transactions
     (representing 0.9%, 0.8% and 0.3% of total revenues in the periods captured
     for FY08, FY07 and FY06, respectively).

     We do not recognize any revenue up-front for such arrangements. All revenue
     is recognized over time, once the software has been delivered. License fees
     are generally recognized over the PCS term; PCS over the PCS term in the
     arrangement (generally longer than the services period); and professional
     services based on our VSOE rates multiplied by the actual hours worked
     during that period. As further discussed below we acknowledge that we did
     not recognize revenues appropriately.

     A literal read of SOP 97-2 paragraph 12 indicates that when VSOE does not
     exist for the allocation of revenue to the various elements of the
     arrangement, all revenue from the arrangement should be deferred until the
     earlier of the point at which (a) such



     sufficient vendor-specific objective evidence does exist or (b) all
     elements of the arrangement have been delivered. However, we believe (as
     supported by Ernst & Young's Software Revenue Recognition, an
     Interpretation ) that acceptable alternatives exist related to this issue.
     Following is an excerpt from Q&A 12-2 of E&Y's software manual which
     describes the "Combined Services" approach.

          A literal read of paragraph 12 would indicate that if VSOE of fair
          value does not exist for both undelivered elements, no revenue should
          be recognized for an arrangement including a software license, PCS and
          services that are not essential to the licensed software until either
          VSOE of fair value is developed, all elements have been delivered, or
          only one undelivered element (either PCS or services) remains.

          However we believe when arrangements include both PCS and services
          that otherwise qualify for separate accounting under SOP 97-2 but for
          which VSOE of fair value does not exist, the following accounting
          policies are acceptable alternatives. Because the following represents
          an accounting policy election, the policy selected by a vendor should
          be consistently applied and, if material, disclosed in the footnotes
          to the financial statements.

          -    The "Combined Services" approach. Using this approach, the entire
               arrangement fee is recognized ratably over the period during
               which the services are expected to be performed or the PCS
               period, whichever is longer, once the software has been delivered
               and the provision of both services has commenced, if all of the
               other basic revenue recognition criteria of SOP 97-2 have been
               met.

               In such situations, the remaining undelivered elements of PCS and
               non-essential services are all services in the broader usage of
               that term. Accordingly, we believe that recognizing the revenue
               over the longest period that services will be provided to the
               customer is consistent with the provisions of paragraphs 58 and
               67 of SOP 97-2.

               Paragraph 58 addresses the accounting for arrangements when
               sufficient VSOE of fair value does not exist to allocate
               consideration to the elements included in the arrangement and the
               only undelivered element is PCS, concluding that the entire
               arrangement fee should be recognized ratably over the period that
               PCS services will be provided to the customer.

               Similarly, paragraph 67 addresses the accounting for arrangements
               when sufficient VSOE of fair value does not exist to allocate
               consideration to the elements included in the arrangement and the
               only undelivered element is services that are not essential to
               licensed software, concluding that the entire arrangement fee
               should be recognized as the services are performed. If no pattern
               of performance is discernible, the entire arrangement fee should
               be



               recognized on a straight-line basis over the period during which
               the services are performed.

               We believe the guidance in these paragraphs clearly indicates
               that AcSEC's intent was that if VSOE of fair value does not exist
               such that the multiple elements included in an arrangement cannot
               be accounted for separately, and the remaining undelivered items
               are services, revenue should be recognized over the period the
               services will be delivered.

     In addition to the E&Y guidance noted above, we also considered paragraph
     6.021 (excerpt below) of KPMG's Software Revenue Recognition manual which
     provides additional support for the "Combined Services" approach.

          Paragraph 12 of SOP 97-2 indicates that, if VSOE of fair value does
          not exist for PCS and, if the only undelivered element is PCS, the
          entire fee should be recognized ratably over the term of the PCS
          arrangement. Paragraph 12 of SOP 97-2 further indicates that, if VSOE
          of fair value does not exist for services that do not involve
          significant production, modification, or customization of software
          and, if the only undelivered element is services, the entire fee
          should be recognized over the period during which the services are
          expected to be performed. When VSOE of fair value does not exist for
          PCS and services that otherwise qualify for separate accounting under
          SOP 97-2, we believe the following accounting policies are acceptable
          alternatives:

                    1.   Because the remaining undelivered elements are both
                         services, recognize the entire arrangement fee ratably
                         over the period during which the services are expected
                         to be performed or the PCS period, whichever is longer,
                         beginning with delivery of the software, provided that
                         all other revenue recognition criteria in SOP 97-2 are
                         met.

                    2.   Defer all revenue until either the services or the PCS
                         is the only undelivered element. If the PCS term
                         expires before the services are completed, the entire
                         arrangement fee would be recognized over the remaining
                         period during which the services are completed
                         (beginning upon expiration of the PCS term), provided
                         that all other revenue recognition criteria in SOP 97-2
                         are met. If the services are completed before the PCS
                         term expires, the entire arrangement fee would be
                         recognized ratably over the remaining PCS term
                         (beginning upon completion of the services), provided
                         that all other revenue recognition criteria in SOP 97-2
                         are met.

          Because this is a policy election, the policy selected by the vendor
          should be consistently applied and disclosed in the accounting policy
          note if material to the financial statements.



     We acknowledge that our revenue recognition methodology is not consistent
     with the "Combined Services" approach but as discussed below did not result
     in material differences. In our arrangements, the total professional
     services fees are not generally stated in the arrangement but rather are
     based on an hourly or daily billing rate which is stated in the contract,
     with an estimate of the total hours to complete the project. We have been
     recognizing professional services revenue, based on the VSOE rates
     multiplied by the actual hours worked during that period rather than
     ratably over the longer of the service period or PCS period. With respect
     to license fee recognition we generally reflected such revenue ratably over
     the longer of the services or PCS term.

     We have quantified the impact on our financial statements had we applied
     the "Combined Services" approach according to the E&Y and KPMG guidance
     which indicates all elements of the arrangement should be recognized
     ratably over the longer of the PCS or services period, or until all
     undelivered elements have VSOE. We have performed a comprehensive analysis
     of the difference between the "Combined Services" approach and the
     methodology we followed. Our analysis indicated that revenue for the
     periods reviewed was understated by $363,000 in the first quarter of FY08,
     overstated by $1,331,000 in FY07 and understated by $249,000 in FY06
     (attached as Exhibit A is a schedule that presents the difference by
     quarter and financial statement line item). We will record a cumulative
     catch-up adjustment of $719,000 to correct this error. This adjustment will
     increase license fees by $107,000, reduce maintenance fees by $34,000,
     and reduce professional services fees by $792,000 in the second
     quarter of FY08. Based on Staff Accounting Bulletin No. 99, Materiality,
     and APB Opinion No. 28, Interim Financial Reporting, we have considered
     both the qualitative and quantitative effects of this error on the
     financial statements for the fiscal years ended March 31, 2007 and March
     31, 2006, and for the quarter ended June 30, 2007, as well as the effects
     of including the error correction in the quarter ended September 30, 2007,
     and have concluded that the effects on the financial statements are not
     material.

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
