This document discusses project estimation and the Constructive Cost Model (COCOMO) for estimating software development costs and schedules. It explains that inaccurate estimates often lead to cost overruns and project failures. Several estimation methods are described like expert judgment, analogy models, and algorithmic models. The COCOMO model uses variables like project size, mode (organic, semidetached, embedded), and effort adjustment factors to estimate effort (in person-months), development time, and staffing needs. The basic, intermediate, and detailed COCOMO models are explained along with the equations used for effort and schedule estimates. Factors that impact productivity like application experience, process quality, and technology are also summarized.

Software Project Management | An Overview of the Software Project ManagementAhsan Rahim
Management is the process of getting things done through others, it is the process of coordinating people & other resources to achieve the goals of the organization. A project is a set of related tasks that are coordinated to achieve a specific objective in a given time limit. A project is well-defined task, which is a collection of several operations done in order to achieve a goal. Software is the program & all associated documentation & configuration data which is needed to make these programs operate correctly.
A Software Project is the complete procedure of software development from requirement gathering to testing & maintenance, carried out according to the execution methodologies, in a specified period of time to achieve intended software product.

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.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
2. Why We Need Estimation?
• Large software systems usually take 200-
300% cost overruns and a 100% schedule slip
• 15% of large projects fail without delivering
anything
• Failures occur basically due to poor
management and inaccurate estimations of
development cost and development schedule
• Developers have to pay the price in schedule
slips
4. Software Cost
• Hardware and software
• Travel and training
• Effort: (dominant factor)
– Salaries of engineers
– Social and insurance
• Other
– Building, heating, lighting
– Networking and communications
– Shared facilities (E.g. library, restaurant)
5. Cost and Price
• The relationship between the software
development cost and charged price from the
customer is not simple
• Price is influenced by
– Organization
– Economy
– Politics
– Business considerations
6. Pricing Factors
• Market opportunity
– Accepting low profit on one project may give the
opportunity of more profit later
– Gaining experience
– Wish of moving into a new segment in market
• Cost estimate uncertainty
– Unsure cost estimate can lead expecting higher
than normal profit
7. Pricing Factors…
• Contractual terms
– Customer allows developers to retain the
ownership of the source code and reuse it in other
projects
• Requirements volatility
– Requirements are likely to change
– Price can be lowered to win the contract
– Higher prices can be charged later for changing
requirements
8. Pricing Factors…
• Financial health
– Developers may be in financial difficulty
– Price can be lowered to win the contract
– Better to make smaller profit than normal profit
than to go out of business
– Break even may also be a solution
10. Expert Judgment
• Experts in both software development and
application domain use their experience
• Advantages
– Relatively cheap
– Accurate if they have knowledge in similar
systems
• Disadvantages
– If there are no experts!
11. Analogy
• The project is compared to a similar project in
the same application domain
• Advantages
– Accurate if project data is available and
people/tools are the same
• Disadvantages
– Impossible without a similar project available
– Systematically maintained cost database is
necessary
12. Parkinson’s Law
• Whatever the resources available is the cost of
the project
• Advantages
– No need to overspend
• Disadvantages
– System is usually unfinished
13. Cost Pricing to Win
• Whatever the customer is able to spend is the
cost of the project
• Advantages
– Can get the contract
• Disadvantages
– Customer satisfaction of the product is less
– Cost does not reflect the work required
14. Algorithmic Cost Modeling
• A mathematical function is used to estimate
the cost
– Inputs: Project, Process, Product
– Decided by project managers
• Historical data are studied to derive the
function
• Commonly used product attribute is LOC
(code size)
15. Software Productivity
• The rate at which individual software
engineers involve in development process is
known as software productivity
• Although quality assurance is a factor in
productivity assessment, the productivity is not
quality oriented
• The useful functionality produced per time unit
should be measured
16. Productivity Measures
• Size related measures:
– Lines of delivered source code
– Object code instructions
– Etc
• Function related measures:
– Functionality of the delivered software
– E.g. Function points
17. Lines of Code
• What programs should be considered as part of
the system?
• Assumption of the model:
– The relationship between system size and volume
of documentation is linear
• Key thing to remember:
– Uncertainty is more important than the initial line
– Seek justifiable bounds
19. Function Points
• Program characteristics are considered
– External inputs and outputs
– User interactions
– External interfaces
– Files used by the system
• Corresponding weights are assigned to each
characteristic
20. FPs and LOC
• FPs can be used to estimate LOC
– LOC = AVC * (Number of FPs)
– AVC is a factor which depends on the
programming language
• Assembly language: AVC = 200 to 300
• 4 GL language: AVC = 2 to 40
• FPs are subjective and dependent on the
estimator
– FP automation is impossible
21. Productivity Estimates
• Real time embedded systems
– 40 to 60 LOC per month
• Systems programs
– 150 to 400 LOC per month
• Commercial applications
– 200 to 900 LOC per month
23. Changing Technologies
• Previous estimating experience does not carry
over to new systems due to changes in
technology
– Use of web services
– Use of CASE tools and program generators
– Development for and with reuse
– Using scripting languages
24. COCOMO
• Constructive Cost Model (COCOMO)
• Estimates are derived as functions of variables
• Data of past projects must be available
• First published by Dr. Barry Boehm in 1981
• Derived through statistical regression of data
from 63 past projects
26. Basic Effort Equation
• (Effort) = A * (Size) ^ (Exponent)
• (Effort) = (EAF) * A * (Size) ^ (Exponent)
• Estimates the man-months (MM) of effort for
software development project
– 1 MM = 152 hours of development
• Size is the source lines of code (SLOC)
27. Modes and Models of COCOMO
• Three modes
– Organic mode
– Semidetached mode
– Embedded mode
• Three models
– Basic model
– Intermediate model
– Detailed model
28. Modes of COCOMO
• Organic mode
– Similar to an earlier project
– Familiar and stable environment
– E.g. Accounting system
• Semidetached mode
– Between Organic and Embedded modes
• Embedded mode
– New project involving new inventions
– E.g. Real-time systems
29. Models of COCOMO
• Basic model
– Roughly estimates project cost, performance and
schedule
• Intermediate model
– EAF (Effort Adjustment Factor) is used from 15
cost drivers
• Detailed model
– Different Effort Multipliers are used for each phase
of project
30. Effort Equation : Basic
• (Effort) = A * (Size) ^ (Exponent)
• A is a constant which depends on the mode of
development
– Organic: 2.4, Semidetached: 3.0, Embedded: 3.6
• (Exponent) is also a constant which depends
on the mode of development
– Organic: 1.05, Semidetached: 1.12, Embedded:
1.20
• Size should be in KSLOC (1000 SLOC)
31. Schedule Equation : Basic
• Minimum time to develop (MTDEV)
• (MTDEV) = 2.5 * (Effort) ^ (Exponent)
• Exponent is a constant which depends on the
mode
– Organic: 0.38, Semidetached: 0.35, Embedded:
0.32
• 2.5 is constant for all modes
• MTDEV is independent from the number of
people assigned
32. Effort Equation : Intermediate
• (Effort) = (EAF) * A * (Size) ^ (Exponent)
• A is a constant which depends on the mode of
development
– Organic: 3.2, Semidetached: 3.0, Embedded: 2.8
• (Exponent) is also a constant which depends
on the mode of development
– Organic: 1.05, Semidetached: 1.12, Embedded:
1.20
• Size should be in KSLOC (1000 SLOC)
34. Schedule Equation : Intermediate
• Minimum time to develop (MTDEV)
• (MTDEV) = 2.5 * (Effort) ^ (Exponent)
• Exponent is a constant which depends on the
mode
– Organic: 0.38, Semidetached: 0.35, Embedded:
0.32
• 2.5 is constant for all modes
• MTDEV is independent from the number of
people assigned
