Data-Driven Estimates With Integrated Historical Data

Published 07/02/24

Maximizing Competitiveness with Data-Driven Estimates Using ProjStream's Integration of Internal Historical Data

In the competitive landscape of government contracting, precise and reliable cost estimation can be the deciding factor between winning or losing a contract. One of the most underutilized assets in this realm is a company's internal historical performance data. When effectively harnessed, this data can significantly enhance the speed and accuracy of cost estimates, making a company more competitive and increasing profit margins. ProjStream, with its robust tools BOEMax and WorkBench, offers unparalleled capabilities to leverage this data efficiently.

The Importance of Historical Performance Data

Historical performance data encompasses a wealth of information from past projects, including costs, labor hours, materials, and productivity rates. This data provides a factual basis for predicting future project costs, enabling estimators to develop more accurate and realistic proposals. Here are some key benefits of utilizing historical performance data:

  1. Improved Accuracy: Historical data offers a realistic foundation for estimates, reducing the reliance on guesswork and assumptions. This leads to more accurate cost projections, which are critical for competitive bidding.
  2. Increased Efficiency: Leveraging existing data streamlines the estimation process, saving time and resources. Estimators can quickly reference past projects to derive estimates rather than starting from scratch.
  3. Enhanced Competitiveness: Accurate and efficient estimating processes allow companies to submit competitive bids without compromising on profitability. It enables more aggressive yet realistic pricing strategies.
  4. Better Risk Management: Historical data helps in identifying potential risks and cost overruns experienced in previous projects, allowing for better risk mitigation strategies in future estimates.

The Role of Cost Estimating Relationships (CERs)

Cost Estimating Relationships (CERs) are mathematical models that correlate cost data with one or more project parameters. By analyzing historical performance data, companies can develop CERs that accurately predict future costs based on specific project characteristics. This is particularly useful for government contractors who often deal with complex and unique projects.

How ProjStream’s BOEMax and WorkBench Enhance Estimation

ProjStream offers two powerful tools, BOEMax and WorkBench, designed to help government contractors leverage their internal historical performance data effectively.


BOEMax is a comprehensive Basis of Estimate (BOE) software tool that facilitates the creation, management, and documentation of cost estimates. Here’s how BOEMax can help:

  1. Data Integration: BOEMax allows for seamless integration of historical performance data into the estimating process. Users can import data from past projects to use as benchmarks for new estimates.
  2. Automated Calculations: With BOEMax, you can develop and apply CERs that automatically calculate costs based on historical data and specific project parameters. This ensures consistency and accuracy in your estimates.
  3. Detailed Documentation: BOEMax provides a structured format for documenting the basis of estimates, making it easier to justify and defend your cost projections to stakeholders and auditors.
  4. Collaboration: BOEMax supports collaborative estimating, allowing multiple team members to contribute to and review estimates in real time, ensuring accuracy and completeness.

WorkBench complements BOEMax by offering advanced capabilities in both estimating and earned value management (EVM). It serves as a lighter-weight application with a lower learning curve, targeting knowledge workers, engineers, and subject matter experts (SMEs). Here’s how WorkBench enhances the use of historical data:

  1. Easy Access to Data: WorkBench provides easy access to historical performance data, making it simple for the target group to leverage this data for their estimates. This accessibility removes traditional barriers, enabling more accurate and informed estimating by SMEs.
  2. Estimating Capabilities: WorkBench offers robust estimating capabilities that integrate seamlessly with the BOEMax and MaxTeam databases. This allows SMEs to quickly generate estimates based on reliable historical data.
  3. Earned Value Management: Beyond estimating, WorkBench includes EVM functionalities that help track project performance against estimates. This dual capability ensures comprehensive project management and cost control.
  4. User-Friendly Interface: WorkBench is designed to be user-friendly, reducing the learning curve and enabling quicker adoption by users who might not have extensive estimating experience.

Enhancing Credibility with Data-Driven Estimates

One of the significant advantages of improving your ability to provide data-driven estimates is the enhanced credibility it brings to your organization. Government agencies and other clients are increasingly looking for contractors who can back up their proposals with solid, data-driven justifications. By leveraging historical performance data and using tools like BOEMax and WorkBench, you can provide more transparent and trustworthy estimates. This not only increases your chances of winning contracts but also builds long-term trust and reliability with your customers.

Leveraging ProjStream Tools for Speed and Accuracy

By utilizing BOEMax and WorkBench, government contractors can transform their estimation process in several ways:

  1. Faster Estimation: The integration of historical data and automated CERs significantly reduces the time required to develop estimates. Estimators can quickly reference relevant data and apply predefined models to generate accurate cost projections.
  2. Higher Accuracy: The use of historical data and validated CERs ensures that estimates are based on real-world data, reducing the likelihood of errors and omissions. This leads to more reliable and defensible cost estimates.
  3. Competitive Advantage: Accurate and efficient estimates allow companies to submit more competitive bids. By understanding the true costs and potential risks, companies can price their bids more strategically, increasing their chances of winning contracts.
  4. Increased Profit Margins: By reducing the uncertainty and risk in estimates, companies can avoid underbidding or overbidding, ensuring that projects are both profitable and deliverable within budget.


Leveraging internal historical performance data is a game-changer for government contractors. It not only enhances the accuracy and efficiency of cost estimates but also provides a competitive edge in the bidding process. ProjStream’s BOEMax and WorkBench are indispensable tools in this endeavor, offering advanced capabilities to integrate, analyze, and apply historical data effectively. By adopting these tools, government contractors can streamline their estimating process, improve their bid success rate, and ultimately achieve higher profit margins.

In the ever-evolving world of government contracting, the ability to accurately predict costs and manage projects efficiently is crucial. With ProjStream, contractors have the tools they need to leverage their historical data to its fullest potential, paving the way for greater success and profitability. Additionally, providing data-driven estimates not only enhances your competitive edge but also builds credibility with your customers, including government agencies, establishing a foundation of trust and reliability.
