As with other project management phases, effort estimate is crucial for software projects. Predicting how many working hours or how long it will take to build software is its definition. The units of measurement are often working hours or work months. It is expensive and challenging to produce software these days. Software projects might incur more financial costs and waste resources if their time or cost estimates are not accurate. Inaccurate work estimation has also been shown to have the potential to cause a project's total collapse [2].
Having a high-quality, accurate model for predicting work is essential to the software project's success. An indication of the estimating model's accuracy may be obtained by contrasting the estimated and actual efforts. Numerous research have demonstrated it. [3] [4] [5] [6] [7] [8] [9] [10] that there are several approaches to handling effort estimation. For software projects, a variety of effort estimating techniques are employed. Furthermore, every technique or model has advantages and disadvantages in terms of the accuracy of the estimations it generates.

Three primary categories may be used to group software estimating approaches: learning-oriented models, non-algorithmic methods, and algorithmic methods [11]. There are several obstacles for each model, and occasionally different models are integrated to increase the estimate's quality. Various algorithms for estimating, such as COCOMO (Cost Constructive Model), Putnam's Model, Parametric Based Models, and Analogy Based Models, rely on mathematical models that generate functions for many variables Puntametc.
Expertise estimation may be stated in non-algorithmic methods including price-to-win estimation, top-down or bottom-up estimation, and poker planning. Three primary elements influence the quality of the estimate: domain expertise, historical data, and team skills [12]. Expert-based models are the ones that are most frequently employed in effort estimate, citing research by [8] [9]. When gathering data and meeting standards is complicated, several methods are employed.
One of the promising and fastest-growing industries in Palestine is information technology. Studies on effort estimating methodologies and strategies in the Palestinian IT industry, however, are still mostly lacking. It has been observed that small to medium-sized development teams, consisting of up to 20 programmers, are typical among software development organizations located in Palestine. We were so inspired to carry out a case study of Palestinian software development firms in order to learn more about the difficulties faced by technical teams and to broaden our comprehension of how they go about estimating software efforts. Our goal is to give Palestinian software development firms a workable collection of suggestions and useful concepts that will enable them to increase their effort estimation and so save significant resources.
This study recommends applying an already used method, triangulation, to assist software development organizations compute their effort estimates more accurately. Triangulation produces better results and is more accurate, particularly for small and medium-sized projects. Additionally, we have developed and validated an application of the triangulation approach that allows Palestinian enterprises to more precisely estimate project costs by adjusting project parameters and resources, hence optimizing project delivery time.
Researchers Rashmi Bubley and Naresh Chauhan focused on the issues with agile approaches and presented a method for precisely calculating the time and cost of producing software. The study also covered a number of agile estimating strategies and the reasons behind imprecise estimations in agile software development. Only small and medium-sized businesses can calculate cost, effort, and time using their suggested technique. The researcher KAFLE conducted an empirical study on software test estimating for his master's thesis. The study involved a case study and the collection of empirical evidence from software development companies in Nepal, with a minimum company size of 30 and a maximum company size of 200. He carried out the case study by speaking with a set of structured questionnaires.
His most significant findings were that the mistake in estimating test effort appeared to be strongly connected to the error in estimating development work. In actuality, a business that had projected a total of 3500 man-months spent 4200 man-months, meaning that 700 man-months of work and cost overruns were required to finish the project. Another business estimated that testing would take 100 man-hours, but in reality, it took 120 man-hours, resulting in 20 man-hour effort and expense overruns.
The study found that most businesses estimate software costs using expert judgment and price-to-win techniques. This is in line with the research methodology they used, which consists of setting research objectives, designing the survey, analyzing and discussing the survey results. The algorithmic model and estimation by analogy were also discovered to be less popular methods for estimating software costs. In addition, they provided an overview and covered a number of the causes of the errors in cost estimate techniques. The software development process model that was utilized to construct the program fits within the estimating model.

The study's key findings are that inaccurate estimations account for approximately 25% of software project cost overruns, that expert-based estimation models are the most widely used model in Palestine, and that team experience, subject-matter expertise, and requirement clarity all have a significant impact on effort estimation accuracy. A model based on use case points, expert judgment, and case-based inference approaches was provided by researchers Mahmood, Kama, Azmi, and Ali in an effort to increase the estimation of the prediction accuracy of software development activities.
The primary justification for selecting this approach over all others is the use of the data gathered from Palestinian IT businesses for the Triangulation technique. However, this data was incompatible with other methods, such as the cocomo methodology. For the reasons listed above, I chose this technology over all others in order to use it on the projects in Palestine.
Finding out what approaches and procedures Palestinian businesses employ is a crucial first step in either improving current practices or coming up with fresh ideas on how to support Palestinian businesses in enhancing the effort and cost estimate for software projects. The current state of this field and the techniques employed by Palestinian companies to estimate effort were discovered through a Google Forms survey published in 2021. The survey consists of a series of questions designed to gather data regarding the state of effort estimation in Palestinian companies at the time of collection. In an effort to gather precise and correct data, the concept of composing a text also steered clear of most multiple-choice answers and included another response.
Expansion of the Triangulation Method

The delivery time can be adjusted, for instance, by adding more software engineers. These inputs are entered into the framework and undergo mathematical operations; as a result, you are given a new deadline for the project's completion, and the desired price is calculated based on the additional sources you added and developer hours to determine developer hourly costs. I included a table that expresses simulations of how to work with this framework and obtain the new project delivery time and cost in order to better grasp the variables and calculations for this framework.

Here, you describe every variable in the table as well as the result
This value, which is the projected project duration for which the effort estimate is computed, is derived using the triangulation approach. Since the value of the risk factor in it will be utilized in the framework, it is measured either in hours, days, or Estimation Units from the triangulation output value, without multiplying the value.

After System Testing, Acceptance Testing is the final stage of software testing

The risk factor is an input from the triangulation technique's inputs, and this number is derived from it.
It indicates the percentage of the project delivery time that has been shortened; for example, adding two developers to the project does not imply that the time has been cut in half.

Research Limitations

They conducted surveys, trials, and validations in the Palestinian software development industry as part of their research. Since it was difficult to get the full cooperation of many of these businesses—many of which are extremely busy and won't spare even a small amount of their valuable time for us—we were forced to depend on the few businesses that did agree to help, including the researcher's own, Asasol Technologies.

Based on earlier research that examined and identified the approaches and strategies employed in Palestinian enterprises for effort estimation, the following will be the focus of this study:
● Survey Palestinian businesses to find more about the strategies and tactics employed in EE.
● Gather information and analyze past software initiatives from Palestinian businesses.
● Choose or create an EE technique that meets the demands of the Palestinian market.
● Verify our work by using our method on software projects that have already been finished. This will allow us to compare the gap between what is (the actual effort) and what is anticipated based on our estimation to determine the accuracy level.

The research serves as a valuable benchmark for Palestinian enterprises and may be regarded as an aid in determining the expenses, schedules, and quantity of resources needed for software development projects. For more precise man-hour estimations, the model can be used as a reference. The Triangle model is appropriate for small teams and modest business initiatives in Palestinian IT enterprises, which is the primary reason we picked it. However, it was discovered that the data did not meet the requirements of the Palestinian IT industry when compared to other formal methodologies (such the COCOMO method).
It should be noted that the triangulation technique may be expanded to modify the number of engineers assigned, for example, in order to regulate and alter the project delivery time. Numerous elements were taken into account, including the combinations of acceptability testing, risk, and mitigating measures.
