About QSM

Pioneers and innovators since 1978.

A History of Industry-Leading Software Estimation Innovation

1978

Larry Putnam forms Quantitative Software Management. Larry’s pioneering research results in the SLIM® Methodology (a sound set of equations and processes to estimate software development projects). Some of the most popular commercial estimation tools today contain parts of the SLIM Methodology.

1979

QSM introduces a mainframe timesharing version of SLIM-Estimate® – the first tool to introduce and use Monte Carlo simulation to perform risk analysis and linear programming for optimized resource planning.

1980

QSM introduces the first standalone desktop software estimation tool (Hewlett Packard 80 series). Innovation in this re-engineered version included graphical outputs and a module that allowed customers to collect and calibrate estimates with their own historical data.

1982

QSM delivers SLIM-Estimate on the IBM PC platform. The Rayleigh Defect prediction model makes its debut in this release.

1983

QSM delivers PCubed: a scaled-down version of SLIM-Estimate for 1- to 3-person projects.

1986

QSM delivers Size Planner – a tool for size estimation. QSM, the first tool supplier to offer this capability to the market, introduces five independent approaches that can be averaged to develop more confidence in the size estimate.

1989

QSM introduces SLIM-Control® – a project tracking and forecasting tool to complement the company’s estimation and planning tool. Innovative capabilities include statistical process control bounds for plan vs. actual comparisons and curve fit forecasting of actual performance data to determine likely completion dates and budgets.

1992

QSM releases SLIM-Estimate for Windows, a total re-engineering for the Windows GUI environment that features graphical control gauges, dynamic risk gauges and multiple estimation views.

1994

QSM Introduces SLIM-Metrics® – another first in the software measurement industry. A powerful project repository, SLIM-Metrics provides query and analysis tools to compare projects and assess process improvements. Innovations include industry benchmark curve fits, customizable screen components and multiple data set comparisons.

1996

QSM delivers a major upgrade to SLIM-Control.

1998

QSM introduces SLIM-MasterPlan – an enterprise project aggregation tool that allows estimators to aggregate estimates of multiple product lines and multiple releases. Innovative features allow graphical shifting of resources to optimize plans or reallocation of resources.

2001

QSM Releases SLIM Suite® – an integrated set of estimation, tracking, and benchmarking tools covering all aspects of the software lifecycle. QSM Introduces Estimate Express® – a comprehensive, yet affordable software project estimation solution designed for smaller companies or project managers with smaller projects.

2003

QSM delivers the SLIM Suite 6.0. More than 40 new and improved features across the entire tool suite make this the premier software estimation product on the market.

2005

SLIM Suite 6.1 is released. The enhanced tool suite features an API to allow seamless integration of SLIM products with other popular project management tools and user-friendly Work Breakdown Structure screens.

2006

QSM publishes the QSM IT Software Almanac, which contains more than 100 pages of in-depth analysis drawn from QSM's world-class database of software projects. SLIM Suites 6.2 and 6.3 are released, bringing improved import/export integration with Microsoft Project and additional features to the SLIM Suite API. The 2006 Users Conferences in the US and Europe give SLIM users the opportunity to share success stories and get a glimpse of the upcoming features of SLIM Suite 7.0.

2007

QSM partners with IBM Rational. Implementations between IBM Rational Method Composer, IBM Rational Portfolio Manager, IBM Rational Team Concert, and SLIM Tools are introduced.

2008:

QSM expands their consulting division into a more defined business unit.  The consulting business grows by 250% (more than triples in size) within the first two years.  QSM helps many commercial and public sector clients achieve a significant ROI with improved project, program and portfolio management of software intensive systems. SLIM Suite 6.4 and SLIM Suite 7.0a are released, interfacing SLIM with Telelogic and the IBM Rational Tool Suite. SLIM-Masterplan is redesigned to support complex enterprise, iterative, and incremental software estimates at the task level and improved integration with MS Project and the MS Office Suite.

2009

SLIM-Suite 7.0c delivers new 2008 industry reference trends and seamless integration between SLIM-Control and IBM Rational Team Concert.

2010

QSM launches the High Performance Benchmark Consortium to help software producers or acquirers quantify and demonstrate performance improvement over time. SLIM Suite 8.0a is released. This major upgrade included seamless web publishing for charts and reports, the ability to customize the PI Calculator and Sizing by History to user supplied historical data, and integration with IBM Rational Portfolio Manager and Focal Point.  In SLIM-Metrics, the new Dataset Comparison Report, Five Star Report, Automatic Trend Line Creation, and new default and template workbooks are new features to improve benchmarking process.  SLIM Suite 8.0d5 fixed various bugs/minor enhancements. In SLIM Suite 8.0e2, 2010 reference trend lines are added.

2011

SLIM Suite 8.0f1 brings enhanced risk reporting for PI, MBI and SLOC to SLIM-Estimate.

2012

QSM releases SLIM-WebServicesa “light and lean” cloud-based version of its flagship project estimation suite, SLIM. In moving its traditional desktop products to the cloud, QSM has opened up SLIM’s capabilities to a much larger, higher-level audience – with the added flexibility of using it as Software as a Service (SaaS) or on-premise. Boasting a lighter footprint and simplified user interface, the new offering seeks to liberate project estimation intelligence from the confines of a few designated power users, into the hands of an entire enterprise.

2013

QSM unveils the latest update to the QSM Project Database. Now in its 8th edition, the database includes more than 10,000 completed real-time, engineering and IT projects from 19 different industry sectors. QSM also releases the fifth version of their Function Point Languages Table, which provides industry averages, organized by programming language, for the source lines of code required to implement a function point (a unit of software functionality).

2014

QSM announces SLIM Suite 8.2, which, for the first time, provides the ability to perform enhanced top-down estimation for capacity planning. Unlike other resource demand management tools that rely on bottom-up estimates, QSM is the first in the industry to provide detailed resource breakdowns, utilizing a more accurate top-down approach. QSM announces update to SLIM-WebServices, which includes a new, streamlined wizard that walks the user through the process of creating a feasibility estimate and provides users with immediate feedback about solution viability and risk. Additionally, SLIM-WebServices 1.2 now includes Round Trip, a capability that allows estimation specialists to download estimates to their desktop for advanced refining in SLIM-Estimate, and then re-upload the new estimate to SLIM-WebServices for the entire team to use.

2015

QSM launches Software Estimation Workshop Series, which includes eight customizable workshops that offer organizations tailored guidance to improve software development processes. QSM recognized by Garter as a Cool Vendor for vendor management. QSM releases SLIM Suite 9.0 which provides users with enhanced data collection features to more accurately plan software development projects based on industry statistics and trends. QSM releases Understanding Software Estimation, Negotiation, and Demand Management: An Executive Primer, a collection of articles that will aid anyone from project managers to CIOs in implementing software estimation, negotiation and demand management methods efficiently to reduce costs.
