delivered the opinion of the Court,
in which Chief Justice PHILLIPS, Justice HECHT, Justice OWEN and Justice GONZALES join.The issue in this mandamus proceeding is whether the trial court abused its discretion by allowing DSC Communications1 to take the apex depositions of two high-level Samsung executives. The court of appeals conditionally granted mandamus relief, concluding that DSC failed to prove that the executives had “unique or superior knowledge that is unavailable through less intrusive means.” — S.W.3d -, 1998 WL 851123. We hold that DSC failed to present any evidence that arguably shows that the executives have unique or superi- or personal knowledge of discoverable information. Thus, the court of appeals did not err in conditionally granting the writ of mandamus because the trial court abused its discretion by overruling Samsung’s2 motion to quash the depositions. We therefore deny Alcatel’s request for mandamus relief.
I
DSC filed this suit alleging that Samsung engaged in a plan to steal a new DSC telecommunication technology known as “intelligent network” and “next generation switching” systems. DSC asserts that Samsung identified and lured a team of *175engineers away from DSC and then specifically assigned them to develop the same type of product they had developed at DSC. DSC claims that Samsung’s actions were the direct result of a plan engineered at the highest level of Samsung’s executive structure, and that highest-level Samsung executives were involved in the plan’s execution at all stages.
DSC noticed the depositions of two high-level Samsung executives, Jin-Ku Kang and Kun-Hee Lee. Kang served as Chairman of defendant Samsung Electronics Co., Ltd. (SEC) during the earliest events giving rise to this case and is currently Chairman Emeritus of that corporation. Lee is currently Chairman and CEO of SEC and formerly served as the Chairman of the Samsung Chaebol3 during the earliest events at issue in this case. DSC and Samsung agree, and therefore we assume, that the Kang and Lee depositions qualify as apex depositions.
Samsung moved to quash both depositions. At the first evidentiary hearing on the issue, the special discovery master assigned to the case deferred ruling until after the deposition of Mr. K.H. Kim, the former President and CEO of SEC at all times relevant to this matter.4 After Kim’s deposition, DSC renewed its request for the Kang and Lee depositions and moved to compel both. After holding another evidentiary hearing, the special discovery master denied Samsung’s motion to quash and ordered that both depositions proceed. Samsung appealed the special discovery master’s order to the trial court. The trial court reviewed the transcripts of these hearings and conducted a third hearing. The trial judge denied Samsung’s appeal and affirmed the special discovery master’s order. Samsung moved for reconsideration. After a fourth hearing on Samsung’s motion to reconsider, the trial judge denied the motion.
Samsung filed a petition for writ of mandamus with the court of appeals. Basing its decision on Crown Central Petroleum Corp. v. Garcia, 904 S.W.2d 125 (Tex.1995), the court of appeals held that DSC had failed to prove that it was entitled to take the apex depositions and conditionally granted mandamus relief. DSC filed a petition for writ of mandamus in this Court, arguing that the court of appeals abused its discretion by granting the writ because the trial court did not abuse its discretion.
II
Mandamus relief is available only to correct a “clear abuse of discretion” when there is no other adequate remedy at law. See Walker v. Packer, 827 S.W.2d 833, 839-44 (Tex.1992). When a party alleges that the court of appeals abused its discretion by granting mandamus relief, this Court focuses on whether the trial court’s ruling was an abuse of discretion. See In re Meador, 968 S.W.2d 346, 350 (Tex.1998) (citing Johnson v. Fourth Court of Appeals, 700 S.W.2d 916, 918 (Tex.1985)). We agree with the court of appeals that the trial court’s ruling was an abuse of discretion and therefore we deny DSC’s request for mandamus relief.
III
This Court first adopted the apex deposition guidelines in Crown Central Petroleum Corp. v. Garcia, 904 S.W.2d 125 (Tex.1995). We held that the apex deposition guidelines apply “[w]hen a party seeks to depose a corporate president or other high level corporate official.” Id. at 128. A party initiates the Crown Central guideline proceedings by moving for protection and filing the corporate official’s affidavit denying any knowledge of relevant facts. The trial court evaluates the motion first by deciding if the party seeking the deposition has “arguably shown that the official *176has any unique or superior personal knowledge of discoverable information.” Id. “If the party seeking the deposition cannot show that the official has any unique or superior personal knowledge of discoverable information, the trial court should” not allow the deposition to go forward without a showing, after a good faith effort to obtain the discovery through less intrusive means, “(1) that there is a reasonable indication that the official’s deposition is calculated to lead to the discovery of admissible evidence, and (2) that the less intrusive methods of discovery are unsatisfactory, insufficient or inadequate.” Id.
While we agree with the court of appeals’ conclusion that mandamus relief was appropriate, we disagree with that court’s phrasing of the Crown Central guidelines. The court of appeals stated: “A party requesting an apex deposition must show that the corporate official to be deposed has an [sic] unique or superior personal knowledge that is unavailable through less intrusive means.” — S.W.3d -, 1998 WL 851123. That phrasing of the guidelines improperly collapses the two discrete inquiries into a single test. Under Crown Central, if the party seeking the deposition has “arguably shown that the official has any unique or superior personal knowledge of discoverable information,” the trial court should deny the motion for protection and the party seeking discovery should be entitled to take the apex depositions. Crown Cent., 904 S.W.2d at 128. The party seeking the apex deposition is required to pursue less intrusive means of discovering the information only when that party cannot make the requisite showing concerning unique or superior knowledge. See id. We recognize that these guidelines could be read as requiring trial courts to undertake two hearings and issue two orders: First, a hearing on whether to grant a protective order and, if one is granted, then a second hearing, after less intrusive methods of discovery have been explored, to determine whether the protective order should be dissolved. We believe that such a mechanical application of the Crown Central guidelines is unnecessary when, as here, the parties have already undertaken extensive discovery and the court has sufficient information to consider both prongs of the guidelines.
In this case, when Samsung moved for the protective orders the parties had already engaged in significant discovery, including more than 300 hours of depositions. At this stage of discovery, nothing in Crown Central precluded the trial court from considering whether DSC had attempted to gain the information by less intrusive means and otherwise satisfied the second Croton Central test. The parties argued both Crown Central tests in the trial court, and both the discovery master and trial judge denied the requested protective orders without specifying the reasons. Accordingly, mandamus is not appropriate if the trial court’s order can be sustained under either Croton Central test. We consider first whether DSC arguably showed that Lee or Kang have unique or superior personal knowledge of discoverable information.
LEE
The most comprehensive discussion of Kun-Hee Lee’s knowledge as it relates to this lawsuit is found in a document submitted by DSC titled: “Kun-Hee Lee’s Significance and Connection to This Lawsuit.” In that document, DSC urges several reasons why Lee’s deposition is necessary. First, under the heading “Kun-Hee Lee Sets Samsung’s Course,” DSC claims that (1) Lee is the leader of the Samsung Chaebol, (2) Lee sets the overall vision for the Samsung companies, and (3) Samsung’s goal is to be one of the world’s top five telecommunications companies by 2005. Second, under the heading “Kun-Hee Lee’s Ties To The Lead Defendant, Samsung Electronics Co., Ltd.,” DSC states that Lee (1) was the chief executive officer and president of SEC, (2) was a long-standing director of SEC, and (3) is *177the largest single owner of Samsung and its subsidiaries.
Evidence tending to support these allegations does not satisfy the first Crown Central test; it merely demonstrates that Lee is a long-time company leader who sets the company vision with lofty goals. Virtually every company’s CEO has similar characteristics. Allowing apex depositions merely because a high-level corporate official possesses apex-level knowledge would eviscerate the very guidelines established in Crown Central. Such evidence is too general to arguably show the official’s knowledge is unique or superior.
In AMR Corp. v. Enlow, 926 S.W.2d 640 (Tex.App.—Fort Worth 1996, no writ), the Second Court of Appeals addressed a somewhat similar argument. In AMR Corp., an American Airlines passenger became intoxicated on his flight and later had a traffic accident with the plaintiff. The plaintiff sued AMR Corp. and American Airlines under the Dram-shop Act. The plaintiff sought the apex deposition of Robert Crandall, AMR’s president, CEO, and chairman of the board, and American Airlines, Inc.’s CEO and chairman of the board, arguing that he “wish[ed] to depose Robert Crandall in order to determine where the authority lies within the organization for making those [alcohol service and flight attendant training] policy decisions so that Plaintiffs can understand how and why those policy decisions were made and what precisely the policies in place were.” Id. at 648. The court of appeals held that “[t]his testimony amounts to nothing more than the simple, obvious recognition that the highest-ranking corporate officer of any corporation has the ultimate responsibility for all corporate decisions and falls far short of the [Crown Central ] standard.” Id. at 644. We agree with the AMR Corp. court of appeals. Testimony that a corporate executive possesses knowledge of company policies does not, by itself, satisfy the first Crown Central test because it does not show that the executive has unique or superior knowledge of discoverable information. See In re El Paso Healthcare Sys., 969 S.W.2d 68, 74 (Tex.App.—El Paso 1998, no writ) (“A generalized claim that a corporate president has ultimate responsibility for all corporate decisions or has knowledge of corporate policy is insufficient to establish that the corporate president has unique or superior personal knowledge of discoverable information.”); see also AMR Corp., 926 S.W.2d at 644.
Under the heading “The Samsung Project At Issue In This Case Smacks Of Chairman-Level Importance,” DSC claims that (1) the “[technology at issue in this case involved huge investments and expected revenue,” (2) “SEC’s commitment to technology in this case is significant to execution” of its plan to be in the top five companies in its industry, (3) “[t]he significance of the project is illustrated by the claims made in this case,”5 and (4) “Kun-Hee Lee has been involved with Samsung’s telecommunications business.” Proof of the importance of the project to Samsung, combined with the allegation that the issue in this case “smacks of chairman-level importance,” at most tends to show that the chairman-level official whose deposition is sought may possess discoverable information. It does not, however, arguably show that the official’s knowledge is unique or superior. Consequently, the first prong of the Crown Central guidelines has not been satisfied with regard to Lee.
KANG
J.K. Kang served as Chairman of defendant SEC during the earliest events that gave rise to this case and is currently *178Chairman Emeritus of that corporation. DSC contends that Kang’s unique or superior personal knowledge is arguably shown by the deposition testimony of Dr. Joo Hyung Lee, an SEC manager who personally oversaw the establishment of Samsung’s Dallas laboratory. Contrary to DSC’s contention, Joo Hyung Lee’s deposition conveys that Kang may have been made aware of information contained in reports prepared by others, but still does not show why Kang’s knowledge may be unique or superior.
In his deposition, Joo Hyung Lee testified that he prepared a status report of the next-generation switching system and presented it to, among others, Song, the Samsung executive in charge of telecommunications, and Kang. Joo Hyung Lee characterized the report as an overview that did not last very long — it was “kind of a simple thing.” He further testified that, other than that single presentation, he had no other communication with Kang concerning the next-generation switching system. Further probing by DSC during Joo Hyung Lee’s deposition indicated that none of the project’s details were conveyed to Kang by Joo Hyung Lee; instead, it was Joo Hyung Lee and Song who were involved in the details:
Q. And I believe section 1.3 [of the document entitled “The Current Status of the Nexb-Generation Switch System”] provides the time line for the next-generation system as you [Joo Hyung Lee] contemplated it at that time?
A. Yes, that’s right.
Q. And if you turn to the next page, I believe this page addresses the— what is called a progress report, and Section 2.1 addresses employment status; is that right?
A. Yes, that’s correct.
Q. And the — the box is indicating the number of people that you had interviewed as well as the response to your advertisements, things like that; is that correct?
A. That’s correct.
Q. And at that time, you were indicating to Chairman Kang that you had 15 total people that you were engaged in employment contract negotiations with?
A. Well, I’m thinking, you know, again, that this and the subsequent stuff, you know, I don’t think we necessarily made a report on that to the chairman.
Q. Are you saying that the items in part two, you’re uncertain whether they were presented to the chairman?
A. I’m thinking that we probably did not specifically make a report on this to him. I mean, this is, you know, all too detailed a level for it to be, you know, reported to the chairman.
[[Image here]]
Q. Did you discuss this with Mr. Song?
A. Yeah, because that’s a matter of the progress, just in a simple fashion.
Q. With respect to item three of the document, which I believe concerns the status report on the facilities or the buildings that you were considering, did you discuss that with Chairman Kang?
A. I don’t recall that I did.
Q. Did you discuss it with Mr. Song?
A. Yes. We just kind of briefly told him about how there was something like this.
Q. And would you turn to the fourth matter in the document on the last page.
A. Yes.
Q. Which I believe is addressing proposed matters; is that correct?
A. Well, proposed, well, basically I, you know, kind of presented my opinions during this time of the — the report.
*179Q. And that was my question. Were these matters presented to Chairman Kang during the presentation?
A. No. I don’t think there — that would have been necessary vis-a-vis the chairman.
Q. Would these have been discussed with Mr. Song?
A. Yes.
Additionally, DSC claims that an index of computer files produced by Samsung contains numerous listings of computer files identified as reports to J.K. Kang on Samsung’s next generation switching system. One of these reports that Kang apparently received a copy of was titled “Action Plans for the Development of the Next Generation Telecommunication System.”
This evidence arguably shows that Kang may have discoverable information. But the first Crown Central guideline requires more; it requires that the person to be deposed arguably have “unique or superior personal knowledge of discoverable information.” This requirement is not satisfied by merely showing that a high-level executive has some knowledge of discoverable information. If “some knowledge” were enough, the apex deposition guidelines would be meaningless; they would be virtually indistinguishable from the scope of general discovery. Although Crown Central did not elaborate on what character of knowledge makes it unique or superior, there must be some showing beyond mere relevance, such as evidence that a high-level executive is the only person with personal knowledge of the information sought or that the executive arguably possesses relevant knowledge greater in quality or quantity than other available sources.
At most, DSC’s evidence establishes that Kang received information related to the underlying facts of this case. A recipient’s knowledge of the contents of a report is not unique or generally superior to the author’s, of course. The record shows that Joo-Hyung Lee’s and Song’s knowledge of the reports to Kang is comparable, if not superior, to the knowledge possessed by Kang. Although both Joo-Hyung Lee and Song were deposed by DSC, the record does not show that Kang possessed information not possessed by Lee and Song and does not show that Kang had relevant knowledge that was greater in quantity or quality than Lee or Song. Combined with other factors, receipt of such a report could arguably support that Kang had unique or superior knowledge. But evidence that an apex official received information requires something more to establish that the apex has unique or superior knowledge of discoverable information.
IV
DSC seeks to distinguish business-related cases like this from tort-related cases like Crown Central and AMR Corp. DSC contends that the trial court, in allowing the depositions to proceed, considered that “this litigation involves two giant international multinational corporations suing each other over trade secrets and corporate direction, policy and defamation.” DSC argues that, “[i]n contrast to cases like ... Crown Central, this is the very kind of lawsuit in which high-level executives would be expected to participate.” (Emphasis in original). The special discovery master apparently agreed with this reasoning by stating:
[TJhis is not the same situation as in Crown Central or the Wal-Mart case, the original apex deposition case. Mr. Lee appears to be the one person at the very top of the chain at Samsung, and it may very well be that he does not know anything that’s relevant to this case, and that can be determined very quickly. But I think that DSC ought to have an opportunity to test that
(Emphasis added).
Even if a lawsuit concerns a business dispute rather than a tort claim, and regardless of whether high-level executives would be expected to participate in a decision relevant to the dispute, the Crown *180Central prerequisites must still be met. Business disputes provide no greater license than any other kind of suit to explore by apex deposition whether a high-level executive knows anything relevant to the case. It may well be true that many tort claims arise without the knowledge or involvement of a high-level officer. Conversely, it may also be true that many business disputes directly involve the decisions or actions of a high-level officer. Regardless of the truth, vel non, of these suppositions, the fact remains that the Crown Central guidelines must be applied.
V
Because DSC failed to arguably show that either Kang or Lee possesses unique or superior knowledge of discoverable information, the trial court’s order cannot be supported under the first Crown Central test. Nevertheless, DSC argues that it has pursued less intrusive means and therefore is entitled to the depositions under Crown Central ⅛ second guideline:
If the party seeking the deposition cannot show that the official has any unique or superior personal knowledge of discoverable information, the trial court should grant the motion for protective order and first require the party seeking the deposition to attempt to obtain the discovery through less intrusive methods .... After making a good faith effort to obtain the discovery through less intrusive methods, the party seeking the deposition may attempt to show (1) that there is a reasonable indication that the official’s deposition is calculated to lead to the discovery of admissible evidence, and (2) that the less intrusive methods of discovery are unsatisfactory, insufficient or inadequate. If the party seeking the deposition makes this showing, the trial court should modify or vacate the protective order as appropriate.... If the party seeking the deposition fails to make this showing, the trial court should leave the protective order in place.
Crown Cent., 904 S.W.2d at 128.
From the record before usj DSC has not shown that it attempted to obtain the information it sought from Kang through less intrusive methods. DSC based its contention that Kang has unique or superi- or knowledge largely on his presence at a written and oral presentation concerning the next generation switching system. But, DSC was allowed to depose Joo-Hyung Lee, who presented the report to Kang and Song. Also, DSC deposed Song, the Samsung executive in charge of telecommunications, who also attended the presentation. Yet, DSC has failed to identify any relevant information that it seeks from Kang that it attempted and failed to obtain from either Joo-Hyung Lee or Song.
In addition, DSC failed to establish that it attempted to obtain the information that it sought from Lee through less intrusive methods. DSC argued that Lee has unique and superior knowledge regarding Samsung’s policies. But the special master allowed DSC to depose Kim, the president and CEO of SEC during the relevant time. Yet, DSC failed to ask Kim any questions about Samsung’s “vision” for telecommunications or any of the other issues DSC now contends justify an apex deposition of Lee. DSC also did not issue interrogatories, requests for admissions, or any other forms of discovery to Samsung regarding its corporate policies. The record simply does not show that the information sought from Lee was sought by less intrusive means or that the information sought was unobtainable from other sources.
Absent a showing that an executive arguably .has unique or superior personal knowledge, a court has no discretion to allow an apex deposition unless the party seeking the deposition establishes that it has attempted to obtain the information through less intrusive methods. The special master provided DSC with the oppor*181tunity to depose other Samsung executives who at least arguably possessed the information DSC seeks. Yet, DSC either failed to take advantage of that opportunity or failed to preserve its attempts in the record. Thus, the trial court abused its discretion in overruling Samsung’s motion to quash the depositions of Kang and Lee.

We agree with the court of appeals’ conclusion that the trial court abused its discretion when it refused to quash the depositions of Kang and Lee because it failed to properly apply the guidelines set forth in Crown Central v. Garcia. Accordingly, we deny the mandamus relief requested by DSC.
