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 17% of the average value of its portfolio.
Portfolio Turnover, Rate	rr_PortfolioTurnoverRate	17.00%
Expense Footnotes [Text Block]	rr_ExpenseFootnotesTextBlock	The Advisor has contractually agreed through February 29, 2024 to waive its fees and/or reimburse fund expenses to the extent necessary to maintain the fund’s total annual operating expenses (excluding certain expenses such as extraordinary expenses, taxes, brokerage, interest expense and acquired fund fees and expenses) at ratios no higher than 0.80%, 1.55%, 1.05%, 0.55%, 0.55% and 0.55%, for Class A, Class C, Class R, Class R6, Institutional Class and Class S, respectively.

Expense Example Narrative [Text Block]	rr_ExpenseExampleNarrativeTextBlock	This Example is intended to help you compare the cost of investing in the fund with the cost of investing in other mutual funds. 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 (including one year of capped expenses in each period)remain the same. Class C shares generally convert automatically to Class A shares after 8 years. The information presented in the Example for Class C reflects the conversion of Class C shares to Class A shares after 8 years. See “Class C Shares” in the “Choosing a Share Class” section of the prospectus for more information. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading]	rr_StrategyHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;text-transform:uppercase;">Principal Investment Strategies</span>
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Main investments. Under normal circumstances, the fund invests at least 80% of net assets, plus the amount of any borrowings for investment purposes, in equities, mainly common stocks, which meet the Advisor’s sustainability criteria at the time of investment. The fund may, at the discretion of portfolio management, invest up to 20% of net assets in investments that do not meet such sustainability criteria. 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 a proprietary environmental, social and governance (ESG) issuer rating in addition to proprietary quantitative models to identify and acquire holdings for the fund.The ESG rating used by the Advisor to meet the Advisor’s sustainability criteria is DWS’s ESG Quality Assessment rating. This rating is generated by a DWS proprietary ESG tool that evaluates and rates an issuer’s performance across a variety of ESG assessment categories, primarily on the basis of data obtained from multiple third-party ESG data vendors and public sources. An additional DWS internal review process allows for changes to the ESG rating. An internal review may occur, for example, if it is deemed that information is not reflected in the existing ESG rating because new information or insights have emerged that the ESG data vendors have not yet processed. Examples of information that may be considered in such internal assessments include, but are not limited to, the announcement of new (or withdrawal from previously announced) climate-related commitments, or the resolution of legacy (or involvement in new) controversies. Portfolio management may use its discretion in considering application of internal assessments on a given rating.The DWS ESG Quality Assessment rating seeks to identify ESG leaders and laggards within industry- and region specific peer groups in terms of overall ESG performance (best-in-class approach). Issuers within the same industry and region-specific peer group are rated on a scale of A (leader) to F (laggard). Issuers with a rating of C or above are deemed to meet the Advisor’s sustainability criteria. In calculating the DWS ESG Quality Assessment rating, the DWS proprietary ESG tool utilizes a proprietary methodology to evaluate ESG scores from multiple third-party data vendors across a broad range of ESG-related issues to arrive at a consensus overall quality ranking intended to reflect which companies may be positioned better to address, and which companies may be more exposed to future ESG risks, relative to their peers. The broad range of ESG-related issues covered include, among others, assessments of an issuer’s carbon emissions including its own emissions and those of its products and services, land use and biodiversity, climate change strategy and vulnerability, product safety and quality, employee management issues including equal opportunities and non-discrimination, freedom of association and right to collective bargaining and occupational health and safety, community relations, human rights issues related to supply chain, business ethics and anti-corruption, and corporate governance matters including executive pay, board diversity and board independence.The quantitative models utilized by portfolio management 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. 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.At the time of the portfolio’s scheduled rebalancing, a security may be sold when a 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, or if its ESG rating falls below a minimum threshold.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.Derivatives. The fund may invest in derivatives, which are financial instruments whose performance is derived, at least in part, from the performance of an underlying asset, security or index. In particular, portfolio management may use options and futures contracts as a substitute for direct investment in a particular asset class or to keep cash on hand to meet shareholder redemptions. Portfolio management may also use put options for hedging and volatility management purposes.The fund may also use other types of derivatives (i) for hedging purposes; (ii) for risk management; (iii) for non-hedging purposes to seek to enhance potential gains; or (iv) as a substitute for direct investment in a particular asset class or to keep cash on hand to meet shareholder redemptions. Derivatives used by the fund do not receive a DWS ESG Quality Assessment rating.
Risk [Heading]	rr_RiskHeading	<span style="color:#000000;font-family:Arial;font-size:10pt;font-weight:bold;text-transform:uppercase;">Main Risks</span>
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. High market volatility may also result from significant shifts in momentum of one or more specific stocks due to unusual increases or decreases in trading activity. Momentum can change quickly, and securities subject to shifts in momentum may be more volatile than the market as a whole and returns on such securities may drop precipitously. 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.Market disruption risk. Economies and financial markets throughout the world are becoming increasingly interconnected, which increases the likelihood that events or conditions in one country or region will adversely impact markets or issuers in other countries or regions. The value of the fund’s investments may be negatively affected by adverse changes in overall economic or market conditions, such as the level of economic activity and productivity, unemployment and labor force participation rates, inflation or deflation (and expectations for inflation or deflation), interest rates, demand and supply for particular products or resources including labor, and debt levels and credit ratings, among other factors. Such adverse conditions may contribute to an overall economic contraction across entire economies or markets, which may negatively impact the profitability of issuers operating in those economies or markets, including the investments held by the fund. In addition, geopolitical and other globally interconnected occurrences, including war, terrorism, economic uncertainty, trade disputes, government debt crises (including defaults or downgrades) or uncertainty about government debt payments, public health crises, natural disasters, climate change and related events or conditions have led, and in the future may lead, to disruptions in the US and world economies and markets, which may increase financial market volatility and have significant adverse direct or indirect effects on the fund and its investments. Adverse market conditions or disruptions could cause the fund to lose money, experience significant redemptions, and encounter operational difficulties. Although multiple asset classes may be affected by adverse market conditions or a particular market disruption, the duration and effects may not be the same for all types of assets.Russia's recent military incursions in Ukraine have led to, and may lead to, additional sanctions being levied by the United States, European Union and other countries against Russia. Russia's military incursions and the resulting sanctions could adversely affect global energy, commodities and financial markets and thus could affect the value of the fund's investments. The extent and duration of the military action, sanctions and resulting market disruptions are impossible to predict, but could be substantial.Other market disruption events include the pandemic spread of the novel coronavirus known as COVID-19, which at times has caused significant uncertainty, market volatility, decreased economic and other activity, increased government activity, including economic stimulus measures, and supply chain disruptions. The full effects, duration and costs of the COVID-19 pandemic are impossible to predict, and the circumstances surrounding the COVID-19 pandemic will continue to evolve including the risk of future increased rates of infection due to significant portions of the population remaining unvaccinated and/or the lack of effectiveness of current vaccines against new variants. The pandemic has affected and may continue to affect certain countries, industries, economic sectors, companies and investment products more than others, may exacerbate existing economic, political, or social tensions and may increase the probability of an economic recession or depression. The fund and its investments may be adversely affected by the effects of the COVID-19 pandemic.Adverse market conditions or particular market disruptions, such as those caused by Russian military action and the COVID-19 pandemic, may magnify the impact of each of the other risks described in this “MAIN RISKS” section and may increase volatility in one or more markets in which the fund invests leading to the potential for greater losses for the fund.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.ESG investing risk. Investing primarily in investments that meet ESG criteria carries the 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. The ESG research and ratings used by the Advisor are based on information that is publicly available and/or provided by the companies themselves or by third parties. Such information may be unavailable or unreliable or out of date and, with respect to information provided by third parties, may be based on criteria that differ among data providers. The reliability and comparability of the data will affect the Advisor’s ESG ratings. The Advisor’s ESG ratings are intended to represent a consensus view of the overall ESG performance of an issuer and therefore a high ESG rating or inclusion in the fund is not an indication that an issuer exhibits positive ESG performance on any particular ESG-related issue. The Advisor’s ESG rating for an issuer may not accurately reflect the issuer’s ESG performance. The Advisor’s ESG ratings are based on peer group comparisons, which may result in a favorable rating for an issuer that might not have received a favorable rating if compared to a broader universe of issuers. Additionally, investors can differ in their views of what constitutes positive or negative ESG characteristics. As a result, the fund may invest in issuers that do not reflect the beliefs and values with respect to ESG of any particular investor.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.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.The fund may become more focused in particular industries, asset classes or sectors of the economy as a result of changes in the valuation of the fund’s investments or fluctuations in the fund’s assets, and the fund is not required to reduce such exposures under these circumstances.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.Securities lending risk. Securities lending involves the risk that the fund may lose money because the borrower of the loaned securities fails to return the securities in a timely manner or at all. A delay in the recovery of loaned securities could interfere with the fund’s ability to vote proxies or settle transactions. Delayed settlement may limit the ability of the fund to reinvest the proceeds of a sale of securities or prevent the fund from selling securities at times and prices it considers desirable. The fund could also lose money in the event of a decline in the value of the collateral provided for the loaned securities, or a decline in the value of any investments made with cash collateral or even a loss of rights in the collateral should the borrower of the securities fail financially while holding the securities.Derivatives risk. Derivatives involve risks different from, and possibly greater than, the risks associated with investing directly in securities and other more traditional investments. Risks associated with derivatives may include the risk that the derivative is not well correlated with the underlying asset, security or index to which it relates; the risk that derivatives may result in losses or missed opportunities; the risk that the fund will be unable to sell the derivative because of an illiquid secondary market; the risk that a counterparty is unwilling or unable to meet its obligation, which may be heightened in derivative transactions entered into “over-the-counter” (i.e., not on an exchange or contract market); and the risk that the derivative transaction could expose the fund to the effects of leverage, which could increase the fund's exposure to the market and magnify potential losses.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.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. For example, the fund’s or its service providers’ assets or sensitive or confidential information may be misappropriated, data may be corrupted and operations may be disrupted (e.g., cyber-attacks, operational failures or broader disruptions may cause the release of private shareholder information or confidential fund information, interfere with the processing of shareholder transactions, impact the ability to calculate the fund’s net asset value and impede trading). Market events and disruptions also may trigger a volume of transactions that overloads current information technology and communication systems and processes, impacting the ability to conduct the fund’s operations.While the fund and its service providers may establish business continuity and other plans and processes that seek to address the possibility of and fallout from cyber-attacks, disruptions or failures, there are inherent limitations in such plans and systems, including that they do not apply to third parties, such as fund counterparties, issuers of securities held by the fund or other market participants, as well as the possibility that certain risks have not been identified or that unknown threats may emerge in the future and there is no assurance that such plans and processes will be effective. Among other situations, disruptions (for example, pandemics or health crises) that cause prolonged periods of remote work or significant employee absences at the fund’s service providers could impact the ability to conduct the fund’s operations. In addition, the fund cannot directly control any cybersecurity plans and systems put in place by its service providers, fund counterparties, issuers of securities held by the fund or other market participants.
