COCOMO, or Constructive Cost Model, is a software cost estimation model developed by Barry Boehm. It categorizes software projects into three modes: Organic, Semidetached, and Embedded. The model uses equations to estimate effort, duration, and personnel required based on project size. Factors such as product complexity, development environment, and team experience influence the final estimation. COCOMO provides a structured approach for assessing and managing software development costs, aiding in project planning and resource allocation.COCOMO, an acronym for Constructive Cost Model, is a widely used software cost estimation technique that aids in predicting the effort, time, and resources required for a software development project. Developed by Barry Boehm in the late 1970s, it classifies projects into three categories: Organic, suitable for small teams with experienced developers; Semidetached, for projects with mixed characteristics; and Embedded, for large, complex systems. The model utilizes mathematical formulas and factors like product attributes, development environment, and team capabilities to generate estimates. By providing a systematic framework, COCOMO assists project managers in making informed decisions during the planning phase, contributing to more accurate budgeting and resource allocation.

Connection Point 2011, Dimension Decisions: A Guide to Selecting Dimensions f...RJ Linehan
At the onset of any enterprise performance management initiative, there are key decisions to be made by the project team. One of those decisions involves selecting the dimensions that will describe the data stored in the application. On the surface, choosing an application’s dimensions may seem relatively easy and is the case for certain solutions. However, more often than not, there are subtle complexities that arise when deciding the dimensions that will satisfy the solution requirements. Without a firm understanding of the impact these decisions have on the proposed application, the project team can end up on an undesirable path.
This presentation will introduce to the audience a standard approach to defining an application’s dimensions while avoiding the pitfalls that arise during the design phase of a project. It will cover the dimensional requirements for each of the EPM tools: Planning, Essbase, and HFM. Finally, the presentation will proceed to address common scenarios and ideal dimensional configurations.
• Standard dimensions for a budget & forecast solution
• Time-based dimensions
• Maximizing the custom dimensions
• Support for more than one accounts dimension
• Attribute dimensions vs. standard dimension
• Dimensional design to support an audit trail
• Dimensional design to support currency conversion
• Leveraging utility dimensions
• Integrating Planning dimensions with HFM dimensionality
Deliver on the Promise of Agile and DevOps TransformationsTasktop
IT organizations are under continual pressure to develop and deliver high-quality applications – at speed - in order to provide key competitive advantage for their company.
They’ve adopted Agile and DevOps practices. But particularly for large organizations with complex application portfolios or compliance pressures, these practices have yet to fulfill the promise of enhancing an organization’s ability to continually deliver customer value. Agile has improved development and test; and DevOps has streamlined getting code into production. But these advances have been localized improvements; to get to the next step software delivery leaders must take a more holistic approach to improving the entire lifecycle.
In this webinar guest speaker, Forrester Senior Analyst Christopher Condo will present his analysis of practices used in modern application delivery and will describe how creating an integrated value stream can help organizations regain their focus on the delivery of customer value.
While traditional performance metrics often measure individual output or adherence to pre-defined plans, measuring performance in agile teams requires a different approach. Agile teams operate in iterative cycles, prioritizing adaptability and learning over rigid goals. So, why do organizations still measure their performance?
By using the right metrics in the right way, organizations can empower their agile teams to thrive and deliver exceptional results.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

𝑐 𝑥 = 𝑆 𝑥 ∙ 𝑅 𝑥
Where:
Sx is the size of leaf x
Rx is the unit cost
13. We need multiple ‘sizes’ to cover NFR
In the absence of a better word we use ‘size’ for each concept that can
act as a base for a cost function for a leaf of the Solution
