Summary of cost estimation software is the process of predicting the effort required to develop a software system. This paper gives an overview of methods for estimating costs, including the latest software advances in this field. Like a number of these models are based on an estimated size of the input software, we first outline the steps of ordinary size. We then select the model estimates that have been proposed and used successfully. The models can be divided into two broad categories: non-algorithmic and algorithmic. Each has its own strengths and weaknesses. A key factor in selecting a model to estimate costs, the accuracy of estimates. Unfortunately, despite the wealth of experience with computational models, the accuracy of these models are not satisfactory. The document includes comments on the performance of estimation models and descriptions of new approaches to estimate costs. Keywords: estimation of the project, effort estimation, models of cost-effectiveness. First Introduction In recent years, the software has the largest component of computer system projects. Most of the cost of software development is on human effort, and most methods for estimating costs to focus on this aspect and give estimates in terms of person-months. accurate estimates are essential for software developers and customers. You can request the submission of proposals, contract negotiation, planning, monitoring and control are used. Underestimation of costs can lead management systems proposed for approval, which exceed their budgets to complete the time with features underdeveloped and of poor quality and failure. may overestimate linked to too many resources for the project, or during contract negotiations, bidding sequence is not successful, the result could lead to job losses. accurate estimate of costs is important because: It can help to categorize and prioritize development projects compared to a global business plan. It can be used to determine what resources are committed for the project and how these resources can be used. It can be used to assess the impact of changes and support to assess rescheduling. Projects may be easier to manage and control when resources are better adapted to real needs. Customers expect real development, in line with the estimate of the cost. estimated cost of the software includes the provision of one or more of the following estimates: costs (usually the person-months) Duration (in calendar time) costs (in dollars) more test models for estimating cost estimate for an effort to generate can then be converted into the project period and costs. Although the work and money are closely related, they are not necessarily related to a single processing function. Effort is often measured in person-months of programmers, analysts and project managers. This effort can be converted to estimate a dollar cost figure by calculating the average content per unit of staff time involved, then multiplied by the estimated cost. Practitioners have to use three basic questions: Which model to estimate software costs fought? What software is used to measure the size – of lines of code (LOC), function points (FP), or point function? What is a good estimate? The most practiced is costing expertise. For many years, the project relied on the experience and develop industry standards in force as the basis for calculating costs. However, estimates based on professional opinion problem: The approach is not repeatable, and the means through an estimate are not clear. It is difficult to find highly experienced estimators for each new project. The relationship between costs and system complexity, size is not linear. Costs tend to increase exponentially with size. The engineering method is valid only if the size of the current project and past projects are similar. Budget management to prevent tampering by the experience and gain higher data raise the question of previous projects. Over the past three decades, many quantitative models of software cost estimation have been developed. They range from empirical models such as Boehm COCOMO models for analytical models. An empirical model used to evaluate data from previous projects for the current project and forms the basis of the analysis of the respective database. An analytical model, on the other hand, the formulas used to solve global assumptions, such as the speed at which the problems of development and the number of problems available. Best models to measure the size, as LOC and FP, were obtained from estimating the size. The accuracy of estimates of the size has a direct impact on the accuracy of the estimate. Although measurements of size can have its drawbacks common equity, an organization may use any method as is used consistent counting. A cost estimate good software should have the following attributes: it is designed and supported by the project leader and team development. It is accepted by all parties as possible. It is based on software cost model with a clearly defined minimum basis. It is based on a database with relevant experience of the project (similar processes, similar technologies, similar environments, people with similar needs and similar) is based. It is sufficiently detailed for its key risk areas and to understand the probability of success is defined objectively assessed. Software cost estimation has always been a major difficulty in software development. Several reasons for the problems identified include: lack of a historical database of costs for the measurement of software development with many interrelated factors, the development effort and productivity, and their relations are not good lack of trained assessors and evaluators with expertise Few understood the sentence is often associated with a poor estimate of the second estimation process of estimating costs is an important part of the planning process. For example, in the planning approach from top to bottom is the calculation used to get the project plan: The Project Manager develops a complete characterization of functionality, size, process, environment, population and quality needed for the project. A macro-level estimate of the total cost and schedule developed with the help of a model for estimating software costs. The partition manager project cost estimate for a work breakdown structure of high level. It partitions the calendar in the data and determines key step in a personal profile, which together form a project plan. The process involves estimating actual cost of the seven stages of production cost estimation setting objectives for a project for data and resources necessary to nail software requirements to work in such detail on the software system as possible to use multiple independent techniques for estimating costs to leverage their combined strengths to compare the various estimates and pass through the estimation process after the project started to monitor actual costs and progress, results and information management project does not matter who the model estimation is selected, users must ensure that what follows in order to obtain the best results: Coverage of the estimated (on some models of generating cost the life cycle, while others do not include the cost of the required step) calibration of the model assumptions and the sensitivity of estimates to the deviation of different parameters of the model estimates of the costs 3 Software design of actual size of software is the most important factor affecting the cost of software. This section describes the five size software used in practice. The line of code and function points are the most popular of the five parameters, the parameters. Line Code: The number of lines of source code delivered, without comments and blank lines and is commonly known as LOC. Although LOC is language dependent, it is the most used software size metric. Most models relate to that extent the cost of software. However, the exact LOC will be earned once the project is completed. An estimate of the size of the code of a program before they are actually built, is almost as hard as the estimated cost of the program. A typical method for estimating the size of the code, the verdict of experts, with a technique called PERT. It brings the verdict of experts from the three possible code sizes: SL, the smallest possible size, the maximum possible size and Sh Sm, the size most likely. The estimate of the S code size is calculated as follows: S1 = S + Sh SM June 4 PERT can also be used for individual components to obtain an estimate of the software system by adding the estimates of all components. Software Science: Halstead suggested that the length and volume of code metrics. code length is used to measure the duration of the program source code and is defined as follows: N = N1 + N2, N1, which is the total number of occurrences operator, and N2 is the total number of occurrences operand. volume equal to the amount of storage space and is defined as follows: V = N log (N1 + N2) where N1 the number of different carriers, and n2 the number of operands that appear in a different program. Function Points: This is a measure on the functionality of the program and was introduced by Albrecht. The total number of points of the function depends on number of distinct (in terms of format and processing logic) type in the following five categories: User-input-types: data types or user control input- Output user types: types of data output to the user, the system of investigation types: interactive commands require a response type of internal file: files (logical groups sharing information sheets) that are used and within the type system of external files: files that are shared or distributed between the system and other systems. Each of these types individually assigned to one of three levels of complexity (1 = single, 2 = medium, 3 = complex) and gives a weighting value between 3 (for single entry) to 15 (for cases complex internal). The figures unadjusted function point (CFU) are given as CFU 5 3 =? NW i = 1 j = 1 ij ij and Nij where Wij are the number and weight of the types of Class I, J. complex example, if the point of the first function has a single project are two inputs (Wij = 3), two complex outputs (Wij = 7) and a complex internal file (Wij = 15). Then UFC = 2 * 3 + 2 * 7 +1 * 15 = 35 The original function point count is either used directly for estimating costs or hang by the factors, the values of the complexity of the project changed. These take into account the degree of distributed processing, the level of reuse, the performance requirement, etc. The final function point count the proceeds from the UFC and the complexity of factors project. The advantage of measurement-point function is that it is based on the specification of the system in the early stages of software development can be achieved. The UFC is also code size estimate used by the following linear formula: LOC = a * b + UFC obtain the parameters a, b by linear regression and all the data of the completed project. Last Counting Practices Manual receive function points IFPUG (International Function Point Users Group administered). extension point of the function: function Point extends the function refers to include algorithms as a new class. An algorithm is like the set of rules that are fully expressed in a problem of significant computational cost to solve, are defined. For example, a square root routine be regarded as an algorithm. Each algorithm is used as a weight of one (primary school) to 10 (highly developed algorithms) and function point is the weighted sum of algorithms, and function points. This is especially useful for systems with very low output and high computational complexity, such as mathematical software, discrete simulation and military applications. A new extension function terminal is the full function (FFP) for measuring real-time applications, taking into account the control aspect of these applications. FFP introduced two new techniques of control data types, and four types of control of new transactional functions. points of the object: Any point feature and FFP extend the functionality of point, point-sized object measured from another dimension. This measure is based on the number and complexity of objects based on the following: screens, reports and 3GL components. Each of these objects is counted and a weight of 1 (one screen) to 10 (3GL component) and the point of the object is the weighted sum of all these elements. This is a relatively new measure and it was not very popular. But because it is easy to use at an early stage in the development cycle and measures of software size very well, this measure in the estimation models like COCOMO II is much used for estimating costs. 4 Estimation There are two main types of methods for estimating costs: algorithmic and non-algorithmic. are computational models differ in the mathematical elegance. Some are simple arithmetic formulas with summary statistics such as means and standard deviations are based. Others go to the regression models and differential equations. improve the accuracy of algorithmic models is the need to adjust or calibrate the model to local conditions. These models are not commercially available for use. may, even with the calibration of precision rather mixed. First, an overview does not exceed algorithmic methods. 4 non-algorithmic methods similar calculation: This method requires one or more projects completed, which may even be that the new project and head of the estimate by reasoning by analogy with the actual costs of previous projects. estimated by analogy is to the detriment of the project level or at sub-system. The total cost of the project level has the advantage that all costs for the system components, while the sub-system has the advantage of a more accurate assessment of similarities and differences between the new project and projects will be considered. The strength of this method is that the estimate of the actual experience of projects. It is not clear is the extent to which the previous project representative of actual constraints, the environment and duties that the new system will be implemented. Experts verdict: This method is to consult one or more experts. The experts provide estimates with their own methods and experiences. expert-consensus mechanism such as Delphi Technique or PERT is used to estimate the contradictions to be resolved. The Delphi technique works as follows: 1) The coordinator of each expert presented a specification and a form of estimates record. 2) Each expert fills the form by one (without consultation with others) and can be transmitted to the questions set coordinators. 3) The coordinator prepares a summary of estimates by experts (including the mean or median) on a form requesting an iteration of the expert estimates and the reasons why the estimates. 4) Repeat steps 2) -3) as many rounds as appropriate. A change of the Delphi technique proposed by Boehm and Fahquhar seems to be more effective: Before the assessment, a joint meeting with the coordinator and experts was convened to discuss the estimate. In step 3), not the experts did not give the reasons for these estimates. Instead, after each round of the estimate, the coordinator shall convene a meeting of experts discuss points where their estimates vary considerably. Parkinson: the principle of Parkinson ‘work increases the volume available’ to complete, the cost to be determined (not estimated) are provided by the resources available, rather than based on an objective assessment. If the software should be in 12 months and 5 people are available, the cost is estimated at 60 person-months. Although there are sometimes good estimation, this method is not recommended because it can provide estimates to be very unrealistic. In addition, this method does not work promote good software engineering practices. prizes: The software is estimated to victory at the best price for the project. The estimate is based on the client’s budget instead of the functionality of the software are based. For example, if a reasonable cost estimate for a project of 100 person-months, but the customer can afford only 60 person-months, it is normal for the estimator is required to change the estimate correspond to the effort of 60 people months for winning the project. This is not to turn a good practice because it is very likely that the delay in delivery caused bad or the power of the development teams to work overtime. Bottom-up: When This approach assesses each component of the software system separately and the results summed to produce an estimate for the entire system. The principle of this approach is that an initial design must exist, as the system is broken down into different elements indicate . Top-down: This approach is the opposite of the bottom-up products. An estimate of the overall cost to the system of global properties that are either non-algorithmic or computational methods. The total cost can then be shared between different components. This approach is more appropriate for estimating costs in the early stages. 4 2 algorithmic methods, calculation methods based on mathematical models to produce the estimate of costs based on several variables are considered as factors of the most important cost is based. algorithmic Each model has the form: Effort = f (X1, X2, …, xn), where (X1, X2, …, xn) cost factors. Existing methods algorithms differ in two aspects: the selection of cost drivers, and the shape of the function f. We first examine the cost factors used in these models, the models to characterize the shape functions and if the models are analytic or empirical. 4 second, cost factors in addition to the size of the software, there are many other cost factors. The most comprehensive set of cost factors proposed by Boehm et al, and in the COCOMO II model. These Cost factors can be divided into four categories: product factors necessary for reliability, product complexity, size of database to use, reuse necessary, the life cycle of documents match must be shared; computer factors: execution time constraint, the constraint of memory, volatile implementation constraints of computing platforms, personal factors: the ability of the analyst, the experience of applications, programming, platform experience language tool and experience, staff continuity, factors of the project: developing multi-site, using software tools, the development schedule required. The above factors are not necessarily independent, and most of them are difficult to quantify. In many models Some factors appear linked form, and some are simply ignored. also take certain factors, discrete values, which must be estimated with a piecewise function. models 4 2 2 linear models are linear of the form n + Effort = A0-ax i = 1 ii where the coefficients A1, …, are chosen to be the best final project data. The work is part of Nelson such models. We agree with the comment Boehm there are too many non-linear interactions in software development for a linear model to work well. “fourth second three multiplicative models, multiplicative models are of the form : xi n = A0 effort? A i = 1, I again, the coefficients a1, …, are chosen to best meet the project data completed. Walston-Felix uses this model, each xi over only three possible values: -1, 0, +1. Doty model also belong to this class each acquisition XI only two possible values: 0, 1. These two models seem to be too restrictive on the values of input costs. Fourth second four models of power function models Power-function have the form: Effort = a’S BS, which is code size, and a, b, (usually simple) functions of other cost factors. This class contains two of the most popular algorithms in use, as follows: COCOMO (Constructive Cost Model) models of this family of models proposed by Boehm. The models have been widely accepted in practice. In COCOMOs, code size S is given in thousands of LOC (Kloc) and effort in person months. A) Basic COCOMO. This model uses three types of (a, b), depending on the complexity of software: (1) for a simple, well understood applications, a = 2 4, b = 1 05, (2) to more complex systems, a = 3 0, b = 1 15 (3) for embedded systems, a = 3 6, b = 1 the 20th COCOMO The basic model is too simple and easy. How many cost factors are not taken into account, it can be used only as a rough estimate. B) Intermediate COCOMO and COCOMO detail. In the intermediate COCOMO nominal cost estimate obtained using the power function with three sets of (a, b) the coefficients was somewhat different from that of the basic COCOMO: (a) for a simple, well understood applications a = third 2, b = 1 05 (2) for complex systems, a = 3 0, b = 1 15 (3) for embedded systems, a = 2 8, b = 1 20 Then, the cost factors Fifteen values between 0 7-1. 66 are calculated (see Table 1) [5]. The total effect is a factor m is obtained as the product of all individual factors and the estimate is obtained by applying M to the nominal estimate. Table 1: Cost factors and their weighting in COCOMO II cost very low low nominal Description High Rating high reliability required software leaving 0th 0th 75 2000 1 88 first January 15, 1940 Size of database data – 0 1994 1st 2000 1st 2008 1st 16 0th CPLX product complexity 0th 75 85 2000 1 15 first January 30 Computing time constraint Complexity – - 1. 2000 1 30 11 1st STOR main constraint – - 1 2000 1 2006 1 21 VIRT volatility virtual machine – the first 2000 1 0 87 15 30 January Turn off the computer processing time – the first 0 87 2000 1 2007 1 15 Personnel Analyst PACS Category rate 1 19 46 1st first 0th 00 86 71 0th application experience AEXP first 29 1st 13 1st 00 0th 0th 91 82 Yield Class 42 first PCAP program 1 00 17 1st 86 0th 0th 70 virtual machine experience VEXP 21 January 1st 10 1st 0th 2000 90 – the experience of language LEXP January 14, 2007 1st first 0th 00 95 – Project MODP practice speaking modern programming 1 24 1st 10 1st 00 91 0th 0th Software Tools TOOL 1 82 24 1st October 1st re 00 91 0th 0th Development Schedule 83 sced first 23 1st 2008 1st 2000 1st 2004 1st 10, while two basic COCOMOs estimating software costs at the system level, working separately, the detailed COCOMO each sub- system and has a distinct advantage for large systems that contain subsystems inhomogeneous. C) COCOMO II Perhaps the most important difference from the COCOMO models is that early exposure to changes in b the following cost factors: precedentedness, development flexibility, architecture and risk resolution of cohesion team and the maturity process. Other differences have been recently added cost factors and models for software architecture and reduce the risk of solidifying. Putnam’s SLIM model and Putnam applies his model in the North-Rayleigh distribution of labor and its conclusion in the analysis of many completed projects are based. The central part of Putnam’s model is called the software equation as follows: S = E ‘(force) 1 / 3td4 / 3, where TD is the software delivery times; E is the factor of environmental capacity development that are derived from historical data may result in the equation software. Size of S is in LOC and the effort in person-year. Another important relationship is established by Putnam TD3 Effort = D0 “where D0 is a parameter called manpower build-up, ranging from 8 (completely new software with many interfaces) to 27 (new software). The combination of the above equation with equation software, we obtain the form of power function: Effort = (D04 / 7 x E-7.9) X S9 / 7 and t = (7.1 x E-D0 7.3) x S3 / 7 Putnam model is also in practice, widely used and SLIM is a software tool on this model to estimate costs and work-based planning. 4th 2nd 5 calibration model using the linear regression is a direct application of the models described above do not reflect local conditions. However, you can adjust the cost elements with local data and linear regression. We illustrate this model with the calibration model based on the general power: Effort a’Sb =. Take logarithm of both sides and y = log (effort), A = log (a) and X = log (S). The formula is transformed into a linear equation: Y = A + Bordeaux under the standard method of least squares to a data set of the previous project (Yi, Xi: i = 1, …, k), we obtain the parameters required B and A (and) for the function of power. Fourth second six discrete models discrete models have some form of tables, which generally refers to the effort, duration, severity and other cost factors. This class of models includes Aron model, the model and the model of Boeing Wolverton. These models gained some popularity in the early days of the estimate, because they are easy to use. 2nd 4th 7 Specimen many other models are available and the following have been used successfully in practice. Price-S model is developed proprietary software cost estimation and maintained by RCA in New Jersey. Based on an estimate of project size, type and difficulty of the model calculates the cost and schedule. SoftCost regarding the size, cost and duration of the danger of address form with the probability distribution of Rayleigh. It contains heuristics to lead the estimators in the treatment of new technologies and the complex relationships between the parameters involved. Algorithmic models are also in Table 2 Table 2 are displayed. Classification of algorithmic models, algorithmic models multiplicative linear discrete Power empirical function including Nelson Walston-Felix to the pan to Boeing and Wolverton COCOMOS Aron Price-Cost Soft Putnam S Analytical Table 3 compares the strengths and weaknesses of different methods. From the comparison, we can conclude that no one method is best for all projects. Parkinson and prizes methods are not suitable for organizations who want to win more business.

In Daubert v. Merrell Dow Pharmaceuticals Inc., 509 U.S. 579 (1993), the Supreme Court overhauled the standards for admitting expert witness testimony in federal court by removing “junk science” from the courtroom and introducing a new reliability test for the permissibility of expert theory and technique.

It would seem the consequence of the ruling would drive attorneys to ensure their expert’s work is solidly founded in the principles of the science from which it is based. The irony is that Daubert seems to have had more of an influence on the frequency and techniques that attorneys use to challenge opposing expert’s testimony instead of verifying the science being used.

According to the 2005 national Guideline study which surveyed 140 scientific experts to determine if Daubert had an affect on lawyers use of expert witnesses, the prevailing strategy seems to be focused on discrediting an opponent’s expert rather than bolstering the credibility of its own expert. In addition, Daubert does not seem to have triggered considerable changes to the level of rigor used in checking an expert’s background before being engaged. Overall, it appears that Daubert has not resulted in significant alterations in preparing and presenting expert testimony, but has definitely influenced the frequency and intensity of expert testimony challenges.

The Daubert factors themselves, as well as the trend in using them to prevent admission of expert testimony, is an indication that lawyers should take the time and effort to better understand the science of their cases, which will benefit them through:
– Identifying appropriate and qualified experts – Evaluating the work product of experts – “Daubert proofing” experts – Challenging opposing experts

Expert Credentials Challenged More Often

Experts feel that the opposing side is challenging their credentials and testimony more often since the Daubert ruling, with 54% agreeing, 24% neutral and only 21% disagreeing.

These results confirm what has been reported earlier that in the wake of Daubert – expert opinion and credentials are challenged more often and more vigorously. However, when experts were asked if attorneys were asking them to assist in challenging the opposing counsel’s expert testimony more often, only 34% of experts agreed with 43% disagreeing and 25% remaining neutral.

This indicates that many attorneys challenge the credibility of the opposing side’s expert(s) without the direct assistance of their own expert(s). They may be using their own expert’s reports and affidavits to challenge the opposing counsel’s experts, but they don’t appear to be asking their own experts to directly assist them in doing so. Many lawyers advise otherwise and indicate that experts should be made part of the litigation team.

Lawyers Aren’t Fully Using the Science

According to the article “Focus On Science, Not Checklists” in the December 1, 2003 issue of Trial written by Bert Black, “lawyers either refuse to or simply cannot learn the science well enough to ‘tell the scientific story’. Instead they fall back on what lawyers do best: They search for legal precedents and try to capture science in just the right checklist of [Daubert] factors.”

To determine if experts have been specifically asked to modify or change their opinions or reports to better comply with the Daubert requirements, Guideline asked experts if attorneys require them to:
– Add citations to references that support their theories / opinions
– Demonstrate their theories/opinions are accepted in the relevant
scientific/technical/engineering communities
– Show their theory/opinion was developed by independent work and not expressly for the purpose of the litigation in which they have been involved
– Demonstrate that their opinions do not drift far from the science or evidence

Medicine is something that enters into our daily activities without us even thinking about it. You don’t consider how your muscles are working or where your food goes after you eat it, but all this can be valuable information in a court case. That’s where expert medical witnesses come in.

An expert medical witness is someone with medical training who is prepared to testify in a case. General practicioners are not usually considered for this type of testimony, lawyers prefer to go to specialists who can really delve into the specifics of the matter at hand. That means it’s not uncommon to see neurologists, plastic surgeons and even oncology specialists on the witness stand.
