These are the fees and expenses you may pay when you buy and hold shares. You may be required to pay commissions and/or other forms of compensation to a broker for transactions in Class S shares, which are not reflected in the tables or the example below. You may qualify for sales charge discounts if you and your immediate family invest, or agree to invest in the future, at least $50,000 in Class A shares in DWS funds or if you invest at least $250,000 in Class T shares in the fund. More information about these and other discounts and waivers is available from your financial representative and in Choosing a Share Class (p. 38), Sales Charge Waivers and Discounts Available Through Intermediaries (Appendix B, p. 97) and Purchase and Redemption of Shares in the fund's Statement of Additional Information (SAI) (p.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover may indicate higher transaction costs and may mean higher taxes if you are investing in a taxable account. These costs are not reflected in annual fund operating expenses or in the expense example, and can affect the fund's performance. During the most recent fiscal year, the fund's portfolio turnover rate was 39% of the average value of its portfolio.

The Example assumes that you invest $10,000 in the fund for the time periods indicated and then redeem all of your shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the fund's operating expenses remain the same. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Main investments. Under normal circumstances, the fund invests at least 80% of total assets, determined at the time of purchase, in equities, mainly common stocks. For purposes of this 80% investment limitation, the term total assets is defined as net assets, plus the amount of any borrowings for investment purposes. Although the fund can invest in companies of any size and from any country, it invests primarily in large US companies. Portfolio management may favor securities from different industries and companies at different times.

Management process. In choosing stocks, portfolio management uses proprietary quantitative models to identify and acquire holdings for the fund. The quantitative models are research based and identify primarily fundamental factors, including valuation, momentum, profitability, earnings and sales growth, which have been effective sources of return historically. These are dynamic models with different factor weights for different industry groupings. The fund's portfolio is constructed based on this quantitative process that strives to maximize returns while maintaining a risk profile similar to the fund's benchmark index.

Portfolio management may sell a security when its quantitative model indicates that other investments are more attractive, when the company no longer meets performance or risk expectations, or to maintain portfolio characteristics similar to the fund's benchmark.

All investment decisions are made within risk parameters set by portfolio management. The factors considered and models used by portfolio management may be adjusted from time to time and may favor different types of securities from different industries and companies at different times.

Portfolio management may consider information about Environmental, Social and Governance (ESG) issues in its fundamental research process and when making investment decisions.

Securities lending. The fund may lend securities (up to one-third of total assets) to approved institutions, such as registered broker-dealers, banks and pooled investment vehicles.

Risk [Heading] rr_RiskHeading Main Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

There are several risk factors that could hurt the fund's performance, cause you to lose money or cause the fund's performance to trail that of other investments. The fund may not achieve its investment objective, and is not intended to be a complete investment program. An investment in the fund is not a deposit of a bank and is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other governmental agency.

Stock market risk. When stock prices fall, you should expect the value of your investment to fall as well. Stock prices can be hurt by poor management on the part of the stock's issuer, shrinking product demand and other business risks. These may affect single companies as well as groups of companies. The market as a whole may not favor the types of investments the fund makes, which could adversely affect a stock's price, regardless of how well the company performs, or the fund's ability to sell a stock at an attractive price. There is a chance that stock prices overall will decline because stock markets tend to move in cycles, with periods of rising and falling prices. Events in the US and global financial markets, including actions taken by the US Federal Reserve or foreign central banks to stimulate or stabilize economic growth, may at times result in unusually high market volatility which could negatively affect performance. Further, geopolitical and other events, including war, terrorism, economic uncertainty, trade disputes and related geopolitical events have led, and in the future may lead, to increased short-term market volatility, which may disrupt securities markets and have adverse long-term effects on US and world economies and markets. To the extent that the fund invests in a particular geographic region, capitalization or sector, the fund's performance may be affected by the general performance of that region, capitalization or sector.

Security selection risk. The securities in the fund's portfolio may decline in value. Portfolio management could be wrong in its analysis of industries, companies, economic trends, the relative attractiveness of different securities or other matters.

Quantitative model risk. The fund's strategy relies heavily on quantitative models and the analysis of specific metrics to construct the fund's portfolio. The impact of these metrics on a stock's performance can be difficult to predict, and stocks that previously possessed certain desirable quantitative characteristics may not continue to demonstrate those same characteristics in the future. In addition, relying on quantitative models entails the risk that the models themselves may be limited or incorrect, that the data on which the models rely may be incorrect or incomplete, and that the Advisor may not be successful in selecting companies for investment or determining the weighting of particular stocks in the fund's portfolio. Any of these factors could cause the fund to underperform funds with similar strategies that do not select stocks based on quantitative analysis.

Medium-sized company risk. Medium-sized company stocks tend to be more volatile than large company stocks. Because stock analysts are less likely to follow medium-sized companies, less information about them is available to investors. Industry-wide reversals may have a greater impact on medium-sized companies, since they lack the financial resources of larger companies. Medium-sized company stocks are typically less liquid than large company stocks.

Focus risk. To the extent that the fund focuses its investments in particular industries, asset classes or sectors of the economy, any market price movements, regulatory or technological changes, or economic conditions affecting companies in those industries, asset classes or sectors may have a significant impact on the fund's performance.

Securities lending risk. Any decline in the value of a portfolio security that occurs while the security is out on loan is borne by the fund and will adversely affect performance. Also, there may be delays in recovery of securities loaned or even a loss of rights in the collateral should the borrower of the securities fail financially while holding the security.

Counterparty risk. A financial institution or other counterparty with whom the fund does business, or that underwrites, distributes or guarantees any investments or contracts that the fund owns or is otherwise exposed to, may decline in financial health and become unable to honor its commitments. This could cause losses for the fund or could delay the return or delivery of collateral or other assets to the fund.

Liquidity risk. In certain situations, it may be difficult or impossible to sell an investment and/or the fund may sell certain investments at a price or time that is not advantageous in order to meet redemption requests or other cash needs. Unusual market conditions, such as an unusually high volume of redemptions or other similar conditions could increase liquidity risk for the fund.

Pricing risk. If market conditions make it difficult to value some investments, the fund may value these investments using more subjective methods, such as fair value pricing. In such cases, the value determined for an investment could be different from the value realized upon such investment's sale. As a result, you could pay more than the market value when buying fund shares or receive less than the market value when selling fund shares.

ESG investing risk. When portfolio management considers ESG factors in its fundamental research process and when making investment decisions, there is a risk that the fund may forgo otherwise attractive investment opportunities or increase or decrease its exposure to certain types of issuers and, therefore, may underperform funds that do not consider ESG factors.

Operational and technology risk. Cyber-attacks, disruptions, or failures that affect the fund's service providers or counterparties, issuers of securities held by the fund, or other market participants may adversely affect the fund and its shareholders, including by causing losses for the fund or impairing fund operations.

Performance Narrative [Text Block] rr_PerformanceNarrativeTextBlock

How a fund's returns vary from year to year can give an idea of its risk; so can comparing fund performance to overall market performance (as measured by an appropriate market index). Past performance may not indicate future results. All performance figures below assume that dividends and distributions were reinvested. For more recent performance figures, go to dws.com (the Web site does not form a part of this prospectus) or call the telephone number included in this prospectus.

The performance figures for Class T shares prior to class inception are based on the historical performance of the fund's Class S shares adjusted to reflect the higher expenses and applicable sales charges of Class T.

The performance figures for Class R shares prior to class inception are based on the historical performance of the fund's Class S shares adjusted to reflect the higher expenses of Class R shares.

Prior to May 31, 2013, the fund had a sub-advisor and a different investment management team that operated with a different investment strategy. Performance would have been different if the fund's current investment strategy had been in effect.
