OPINION
This is a sentencing appeal by the state which addresses two issues: whether there exist appropriate aggravating factors to support a durational departure in sentencing and whether a criminal defendant may waive the right to be sentenced under the Minnesota Sentencing Guidelines. 1 We hold that suffi- *775 eient aggravating factors exist to support the upward departure and further, that a criminal defendant may knowingly, intelligently, and voluntarily waive his right to be sentenced under the guidelines.
The facts of the crime at issue are uncontested. Respondent entered a security building in south Minneapolis on a pretext. Although the record contains no evidence regarding his reason for choosing the victim’s apartment, he admits that he knocked on her apartment door and declared that he had video tapes to deliver. When the victim, a 74-year-old woman who walks with a cane, answered her door, respondent grabbed her cane, throwing her off balance, and pushed her to the floor. He then reached inside to grab the victim’s purse, which hung on a door knob in the apartment, and fled. When later caught, respondent admitted he stole the purse for money to purchase drugs.
Respondent pled guilty to a first-degree burglary charge, Minn.Stat. § 609.582, subd. 1(c) (1994), and agreed to a plea bargain involving the dismissal of an additional charge of simple robbery and a recommendation to the trial court regarding sentence. Under the guidelines, the presumptive sentence for a first-degree burglary charge for someone with respondent’s criminal history is 48 months in prison. The prosecutor and the defense attorney recommended that the court depart upward in respondent’s sentence, but stay the sentence and order respondent to enter chemical dependency treatment. Respondent was accordingly sentenced to 96 months and the imposition of the sentence conditionally stayed. The imposed sentence was therefore a “downward dispositional departure” and an “upward du-rational departure,” both of which require the trial court to state its reasons for depart-mg on the record. Minn. Sent. Guidelines II.D.204 comment (1994). As explanation for the durational departure, the trial court cited the victim’s vulnerability due to age, an aggravating factor from the guidelines’ nonexclusive list. See Minn. Sent. Guidelines § II.D.2.b.(l). Subsequently, respondent violated his probation and the trial court executed the stayed sentence.
On appeal to the court of appeals, respondent contested the upward durational departure, arguing that there were no aggravating factors present.
State v. Givens,
No. C2-95-36, slip op. at 2,
On appeal, the state contests the court of appeals’ reasoning, urging that the facts do indeed demonstrate that respondent exploited the victim’s age and infirmity and also invaded her zone of privacy. The key, con *776 tends the state, is the fact that respondent proceeded with the crime once the victim opened her door. In other words, the state argues that, had respondent knocked on a different door and found himself facing a large, muscular man, he probably would not have continued with the burglary. In addition, respondent entered the apartment building under false pretenses and moved inside the apartment sufficiently to knock the victim down and grab her purse, thus imph-eating the “zone of privacy” departure factor.
Respondent argues that the facts necessary to support the trial court’s durational departure are absent in this case. He insists that the court of appeals’ reasoning was correct and therefore, in order for an aggravating factor to be present, a defendant must have taken advantage of that factor.

No. C2-95-36, slip op. at 4. In addition, respondent asserts that regardless of the presence or absence of aggravating factors, the upward departure violated the concept of proportionality governing the application of the guidelines.
See State v. Garcia,
The Minnesota Sentencing Guidelines are intended to promote rational and consistent sentencing. The Sentencing Guidelines Commission developed a simple cross-referencing grid so courts could easily reach a “presumptive” sentence proportional to the severity of the offense and the extent of the offender’s criminal history.
See
Minn. Sent. Guidelines § IV (1994). This court has held that the presumptive sentence should be imposed, unless the circumstances of the crime indicate that a departure is warranted.
Garcia,
Among the departure factors included in the guidelines is the exploitation of the victim’s vulnerability. The guidelines state that when a defendant commits a crime against a victim who was “particularly vulnerable due to age, infirmity or reduced physical * * * capacity * * * which was known” to the defendant, the trial court may depart upward when imposing the sentence. Minn. Sent. Guidelines § II.D.2.b.(l). Once the victim opened the door, respondent could not have failed to realize that she posed no threat to his intentions of stealing money to buy drugs. At that point, respondent knew of the victim’s age and infirmity. He then actively capitalized on those aspects of his chosen victim by reaching for her cane to knock her to the floor.
We hold, on these facts, that the upward durational departure was justified by respondent’s exploitation of the victim’s vulnerability and that the sentence does not exaggerate the seriousness of the crime. 3 The trial court acted within its discretion when it sentenced respondent.
Although our holding on the departure factor could be dispositive of this case, we deem it appropriate to reach the other issue raised by the state on appeal. The state asks this court to establish a rebuttable presumption that if a defendant agrees to a departure as *777 part of a plea bargain, the departure needs no additional justification.
Respondent notes that in
Garcia,
we stated that an attempt “by the parties to limit sentence duration does not create a ‘substantial and compelling circumstance’ which may be relied upon as justifying a departure from the Guidelines.”
Garcia,
We believe that the real question raised by this case is whether a defendant may waive his or her right to be sentenced under the guidelines. Since 1980, defendants in Minnesota have benefitted from the protection of the guidelines’ regulation of sentencing discretion. The guidelines exist to maintain the presence of rationality in sentencing decisions. To the extent that they restrict the discretion of a sentencing judge, the guidelines offer a measure of evenhand-edness and predictability to defendants. Their purpose is to ensure that defendants will not be sentenced based upon inappropriate grounds such as race, gender or social or economic status.
However, it has long been settled law that courts will honor a defendant’s lawful, “intentional relinquishment or abandonment of a known right or privilege.”
Johnson v. Zerbst,
Such a waiver, however, must conform to the usual limitations accompanying the waiver of constitutional or statutory rights, that is, it must be knowing, intelligent, and voluntary.
See Edwards v. Arizona,
Because we find that substantial and compelling circumstances exist to support the trial court’s departure in this case, there is no need to inquire into the propriety of the defendant's waiver in this case. As we noted above, the trial court did not abuse its sentencing discretion. The decision of the court of appeals, therefore, is reversed.
Reversed.
Notes
. Minnesota's sentencing guidelines system is a statutory creation. The legislature established the Sentencing Guidelines Commission and charged it with the creation of standards to guide sentencing discretion. Minn.Stat. § 244.09 (1994). The Minnesota Sentencing Guidelines *775 are designed to imbue the practice of sentencing with a measure of consistency and rationality and a respect for the realities of the resources available to corrections officials. The Sentencing Guidelines Commission also created a grid providing a simple means of combining criminal history and offense severity to reach a "presumptive" sentence. Minn. Sent. Guidelines § I (1994). The trial judge is to impose the presumptive sentence, unless substantial and compelling circumstances are present to justify a departure from that presumptive sentence. Id. at II.D. The commission has provided a nonexclusive list of factors that may be used to justify a departure. Id. at II.D.2.b. If a judge decides to depart, he or she must provide written reasons specifying the nature of the circumstances prompting the departure. Id. at II.D.
. The "zone of privacy” departure factor is a judicial creation, which recognizes the impact on a victim of the occurrence of the crime in the victim's home.
See State v. Morales,
. Because we find the aggravating factor cited by the trial court to be sufficient to justify the departure, we do not address whether the additional aggravating factor identified by the state, invasion of the victim's zone of privacy, is present.
. To the extent that
