This paper focuses on the importance of software metrics and discusses their key role in software development processes perspective to Sri Lankan organizations and systematically analyses the importance of software metrics in software development projects.

Keywords: Software metrics, Software development project, Sri Lanka, Software development process, engineering discipline 1. The field of software metrics has grown up out of two needs.

One is the need for software developers to be able The concepts of software metrics are coherent, to manage the software development process. For understandable and well established. Therefore it is more example, developers need to determine the resources or useful to develop the software projects with good quality time needed to deliver a product or whether the software and easy to fulfil the customer requirements.

The other need comes from researchers, who want to be able to objectively define Therefor this research paper aims to discuss the and measure software attributes in order to get a better Importance of Software Metrics for Software understand about software engineering [1]. And this field Development Project in Sri Lankan software industry and of software metrics is constantly changing. Therefore how is the appearance of Software Metrics effect the there is no standard set of metrics, and new measures are software practitioners in Sri Lankan and how the always being proposed.

Metrics researchers have to organizations in Sri Lanka succeed their software modify their existing parser tools in order to development projects using Software Metrics.

This is a real challenge to developers since such tools usually have very complex The rest of this paper is organized as follows. Section 3 source code [2]. Section 4 describes the methodology of this paper. Result and discussion is Software metric is a measure of some property of a piece presented in Section 5 and finally Conclusion is of software or its specifications. This can be classified into presented in Section 6.

Product metrics describe the 2. Process Anda et. And project metrics describe the project use case model that use to describe the functional characteristics and execution. Such as it explains the requirements of a system. The aim of this paper is to number of software developers, the staffing pattern over provide guidance for other organizations that want to the life cycle of the software, cost, schedule, and improve their estimation process applying use cases.

The results indicate that the guidance provided by 4. Our experience is also that the design of the use case models has a strong 4. Since the questionnaire is the best method to gather high accuracy real time data by using several simple steps, Fenton had discussed the reliability of a system is the team has decided to do a questionnaire to gather probability that the system will execute without failure in information.

A quantitative approach using a a given environment for a given period of time. Classical questionnaire is adopted to understand the background regression-based approaches to modeling and predicting and the perception of practitioners in Sri Lanka towards software defects and resources are in adequate and often software process and software metrics methods.

Based on flawed. They do not provide managers with decision the feedback for the surveys conducted, the research team support for risk assessment and hence do not satisfy the decided to confine this research to find the answer to the most important objectives of software metrics. Rawat et. This paper examines the realm of software IT related people as participants from Sri Lanka. Results can be improved further as they Start acquire experience with variety of software metrics.

These experiences can yield tremendous benefits and betterment in quality and reliability [7]. Idea about the software metrics Fenton et. The new method, using Bayesian nets, provides true decision-support and risk analysis potential. They do not provide managers with decision support for Do you use software metrics for risk estimation and hence do not satisfy the most development projects?

Farooq et. This paper mainly focused on software test metrics, discussed their key role in software Projects without using metrics testing process and also classified and systematically analyses the various test metrics.

They presented that software measurement and metrics assist people a lot in See any difference between projects evaluating software process as well as the software product [9]. What are they? Identify the current usage of software metrics for How it works and its software development project. Analyse the pros and cons of software metrics for software development project.

Identify the knowledge about software metrics among Stop industrial people. Administering of the questionnaire, finally send results to participants.

In order to collect responses, the team carefully selected 85 participants from Organizations in Sri Lanka. Each participants, was contacted and the questionnaire was emailed. A questionnaire done with 60 industry participants and those people are who currently working on a software development project or have previously worked in a software development projects. So the audience of this questionnaire can be considered as industry experience group of participants.

Figure 5 : People who used software metrics. Business, technical and of using software metrics in software development project managers must be able to defend the basis of their projects.

Some industrial people consider software metrics as a time consuming process since it takes some additional time from the development time. And it requires knowledge about usage of software metrics; it can be seen as a problem with software metrics since all the organizations are not familiar with those knowledge Figure 8 : Projects that have done with and without areas. Some organizations and industrial people are not ready to use software metrics because they do not like software metrics.

Using software metrics, can confident with their experiences and considered as no need have a quality product at the end of the project, with less of metrics.

This reduces the ambiguity that Our sincere gratitude goes out to all the people who have often surrounds complex and constrained software contributed to the success of this research paper. And projects. Metrics provides an effective rationale for finally we thank all the anonymous reviewers for their selecting the best alternatives.

For example, the current insightful comments. E Fenton and S. Scotto, A. Sillitti, G. Succi and T. Rawat, A. Mittal, S. Fenton and M. Anda, H. Dreieme, D. K Sjoberg, and J. Farooq, S.

Project Metrics :

How do you know which parameters are the most appropriate to define and measure the successful completion of a process? What are some software development metrics examples? Project managers have a wide variety of metrics to choose from. We can classify the most commonly used metrics into the following groups:. These are metrics that pertain to Process Quality. They are used to measure the efficiency and effectiveness of various processes. These are metrics that relate to Project Quality.

Software Quality Metrics Overview

A software metric is a measure of software characteristics which are measurable or countable. Software metrics are valuable for many reasons, including measuring software performance, planning work items, measuring productivity, and many other uses. Within the software development process, many metrics are that are all connected. Software metrics are similar to the four functions of management: Planning, Organization, Control, or Improvement. Product Metrics: These are the measures of various characteristics of the software product.

Software Testing Metrics are the quantitative measures used to estimate the progress, quality, productivity and health of the software testing process. The goal of software testing metrics is to improve the efficiency and effectiveness in the software testing process and to help make better decisions for further testing process by providing reliable data about the testing process. The ideal example to understand metrics would be a weekly mileage of a car compared to its ideal mileage recommended by the manufacturer.

Software metrics can be classified into three categories: product metrics, process metrics, and project metrics. Product metrics describe the characteristics of the product such as size, complexity, design features, performance, and quality level. Process metrics can be used to improve software development and maintenance. Examples include the effectiveness of defect removal during development, the pattern of testing defect arrival, and the response time of the fix process.

A software metric is a standard of measure of a degree to which a software system or process possesses some property. Since quantitative measurements are essential in all sciences, there is a continuous effort by computer science practitioners and theoreticians to bring similar approaches to software development. The goal is obtaining objective, reproducible and quantifiable measurements, which may have numerous valuable applications in schedule and budget planning, cost estimation, quality assurance, testing, software debugging, software performance optimization, and optimal personnel task assignments. As software development is a complex process, with high variance on both methodologies and objectives, it is difficult to define or measure software qualities and quantities and to determine a valid and concurrent measurement metric, especially when making such a prediction prior to the detail design. Another source of difficulty and debate is in determining which metrics matter, and what they mean. A specific measurement may target one or more of the above aspects, or the balance between them, for example as an indicator of team motivation or project performance. Some software development practitioners point out that simplistic measurements can cause more harm than good.

Key Project & Process Metric Groups

Рядом со мной Сьюзан Флетчер. В тот момент Сьюзан поняла, за что уважает Тревора Стратмора. Все эти десять лет, в штиль и в бурю, он вел ее за. Уверенно и неуклонно. Не сбиваясь с курса. Именно эта целеустремленность всегда изумляла, эта неколебимая верность принципам, стране, идеалам.

И развязали против Стратмора непримиримую войну. ГЛАВА 24 Дэвид Беккер стоял в телефонной будке на противоположной стороне улицы, прямо напротив городской больницы, откуда его только что выставили за причинение беспокойства пациенту под номером 104, месье Клушару. Все внезапно осложнилось, пошло совсем не так, как он рассчитывал. Мелкая любезность, которую он оказал Стратмору, забрав личные вещи Танкадо, вылилась в поиски таинственного кольца, как в известной игре, где нужно находить спрятанные предметы. Дэвид только что позвонил Стратмору и рассказал о немецком туристе. Новость не обрадовала коммандера. Выслушав подробности, он долго молчал.

 Ты знаешь ее фамилию. Двухцветный задумался и развел руками.

Она пыталась осознать истинный смысл случившегося. Всю свою жизнь она посвятила взламыванию шифров, отвергая саму возможность разработки абсолютно стойкого шифра. Любой шифр можно взломать - так гласит принцип Бергофского. Она чувствовала себя атеистом, лицом к лицу столкнувшимся с Господом Богом.

И, словно возражая ей, в ее мозгу эхом прозвучали слова Хейла, сказанные чуть раньше: Танкадо не раз мне писал… Стратмор сильно рисковал, взяв меня в АНБ… Рано или поздно я отсюда слиняю. Но Сьюзан физически не могла примириться с тем, что увидела. Да, Грег Хейл противный и наглый, но он же не предатель. Зная, чем грозит агентству Цифровая крепость, не мог же он участвовать в заговоре по ее созданию.

Сьюзан положила голову ему на грудь и слушала, как стучит его сердце. А ведь еще вчера она думала, что потеряла его навсегда. - Дэвид, - вздохнула она, заметив на тумбочке его записку.  - Скажи мне, что такое без воска. Ты же знаешь, что шифры, которые не поддаются, не выходят у меня из головы.

Джабба вздохнул и снова вытер пот со лба. По выражению его лица было ясно: то, что он собирается сказать, не понравится директору и остальным.

Конец веревочки. Он набрал номер. - Escortes Belen, - ответил мужчина.

Вероятно, Цифровая крепость - это стандартный алгоритм для общего пользования, тем не менее эти компании не смогут его вскрыть. - Это блистательная рекламная операция, - сказал Стратмор.  - Только подумай - все виды пуленепробиваемого стекла непроницаемы для пуль, но если компания предлагает вам попробовать пробить ее стекло, все хотят это сделать. - И японцы действительно верят, что Цифровая крепость - это нечто особенное. Самое лучшее из того, что можно найти на рынке.

Секунду спустя оба, залившись краской, делали доклад директору Агентства национальной безопасности. - Д-директор, - заикаясь выдавил светловолосый.  - Я - агент Колиандер. Рядом со мной агент Смит.
