COMMUNICATION AND ANALYSIS SKILL DEVELOPMENT PROGRAMME
(CASP)
HOURS/WEEK: 06 TOTAL HOURS: 96
Competence to be developed (in place of objectives):
I. To present orally about any topic of the student’s interest to the rest of the class without the assistance of media or any other aid (only talk) for about 10 minutes creating interest in the listeners and sustaining the interest with a meaningful conclusion.
II. To prepare a study report on any product/service in comparison with another one that is comparable from technical specification to customer satisfaction.
36
III. To present with the aid of slides (6 to 10) about the study conducted above to the rest of the class in about 10 minutes with the use of print for information and slides for graphs, pictures, images, video and animations etc.
Note to teachers:
A teacher may guide only 6 to a maximum of ten students per year. This is to ensure active participation of each learner.
All 96 hours need NOT be contact hours by the teacher. Students may be encouraged to do activities on their own with peer group to ensure higher level of participation.
There are ten different tasks to be completed in the course of 96 hours. On completion of each task, record the result and the marks along with the initials of the learner for future reference, inspection and evaluation.
A few activities are suggested under each task. Teachers can improvise on the list and add more activities as they progress from one batch to another.
Students should not be compared with each other; instead they must be compared to the standards given against each task.
The standard suggested is minimum requirement, learners may excel. The services of those who excel may be utilised to guide other learners to reach the suggested minimum.
The tasks 8, 9 and 10 may be evaluated in the presence of the total group so that learners get the benefit of knowing the inferences made by others and even their presentation style.
Details of tasks to be completed:
Task 1 – Communication skills: - One to one personal communication. 6 hrs. 5 marks.
Practice in pairs through role play
Suggested activities:
1. Telephonic conversation of a customer and supplier. 2. Front office receptionist and a visitor. 3. Negotiation between suppliers of equipment/chemical to a technical representative of a
manufacturing unit. 4. Conversation between quality inspector from the bulk buyer to the shop floor supervisor
regarding maintenance of any quality.
Standards to be met:
Given a telephone number, a student must be able to call and gather information from the person, sustaining the conversation for about 3 min using proper etiquettes and report on the enquiry made about the product or service. [e.g., call a toll free number to ask details about a product or service]
Given a situation, a student must be able to talk to a person face to face in simulation, gather information about a product, discuss about it and also negotiate with him in the specified time (here, time can be specified by the teacher as per the need).

from an oxide (alumina) or non oxide (silicon carbide) Ceramics matrix re in forced by whiskers
of silicon carbide (Sic) titanium boride (TiB2), aluminum nitride (AlN), zirconium oxide (ZrO2) and
other ceramic fibers . Most of CMC are reinforced by silicon carbide fibers due to their high
strength and stiffness (modulus of elasticity)
Whiskers in corporate in a short –fiber ceramics matrix composites improve its toughness
resisting to cracks propagation. However a character of failure of short fiber reinforced
materials is catastrophic
Long fiber (continous) composites are re in forced either by long mono filament of long multi
filament fibers
The best strengthening effect is provided by dispersed phase in form of continous mono
filament fibers, which are fabricated by chemical vapour deposition (CVD) of silicon carbide on
a substract made of tungsten (W) or carbon(C) fibers.
Mono filament fibers produce stronger interfacial bonding with the matrix material improving
its toughness
Failure of long-fiber ceramics matrix composite is not catastrophic.

attacks the respiratory system and causes lung cancer then it spread total cancer problems
in the employees. And also it spreads all around the industry and causes problems to the
public living around the industry.
Precautionary measures: the employees are instructed very strictly to wear shoes,
breathing masks and hand gloves during working with the carbon and graphite
manufacturing. It is better to locate the industry away from the public colonies, towns and
cities at least in 5km distance to safe guard the public health.
The rejections from the carbon ceramics industries instead of throwing as a garbage which
is not a bio degradable material cause’s damage to the environment.
Precautions- The sintered rejected graphite products must be recycled and used in the
batches which saves the nature and also gives profit to the industry.

ROADMAP FOR PROJECT GUIDES
128
1. The project work is proposed to be carried out during the V and VI semesters so that
learners prepare during the V semester, do some field work based on the preparation
during the mid semester vacation and report the analysis and inferences during the VI
semester.
2. The learners would reach a level of maturity by the time they reach V semester and so a
meaningful project lasting for a year can be executed by them.
3. To execute the project with involvement needs constant guidance and monitoring of the
progress of the learners by the guide.
4. This does not mean teacher has to advice learners.
5. Be confident about the ability of the learner and “intellectually provoke” them with
challenging questions. These questions should prompt the learners to search information
and update themselves (to be carried out during the first two weeks).
6. Do not feed information to learners. Instead crate a „cognitive dissonance‟ (a challenging
question or situation that the learner is not able to find an immediate answer but feels the
need to search for information to find a solution).
7. Defer judgement on learners and give them identified sources if required like a journal
article, book or a web site.
8. Even if the learners report their inability to solve do NOT give or prescribe a solution.
9. Be patient and give time for the learner to construct his knowledge.
10. Give corrective feedback to the learner by challenging his solutions so that his logic is
questioned and it develops further.
11. This leads to the first activity viz., literature survey and conceiving a project.
12. During this phase meet the project team in a group and create a healthy competition
among the learners to search different sources and synthesise their findings in the group.
13. Aim for bringing out a workable innovative project conceived within the first eight weeks
as given in the schedule attached.
14. During these two phases and the third phase the teacher should assess the strengths and
weakness of the members of the group and allocate differential work to team members on
the remaining tasks to be carried out during the next thirty weeks.
15. This is to ensure active participation of all the members of the team.
16. By the end of the twelfth week finalise the project and a schedule of further activities for
each member indicating the time frame in which his activities are to be executed may be
made ready. A soft copy of this schedule may be collected from each learner by the
guide to follow up.
129
17. This schedule prepared by each learner need to be documented for checking further
progress of the project.
18. The next few phases of the project may require active guidance of the guide especially
regarding the sources of collecting data, if a sample data is to be collected the number of
units has to be decided, collating the data/fabricating, tryout/analysis and finally coming
out with meaningful conclusions or models or application.
19. Data like models, designs, technical specifications, source code, protocols and original
records need be collected from one authentic source as there will not be any variation.
The teacher may guide the learners to authentic source.
20. Data having limited variability like product/service quality, processes and standards,
procedures need to be collected from a sample as there is a variation. The number of
units from whom (source) the data is to be collected is called sample. The sample needs
to be representative of the expected variation. The decision on the size of the sample and
the number of units need guidance from the teacher. For example, data regarding the
quality of a product/service need be collected from 3 to 5 personnel at different levels of
a service provider or dealers of a product. The numbers given are suggestive but a guide
based on his experience has to make valid suggestions.
21. Data having a wide range of variation like customer satisfaction where the customers are
members of the public need a larger number of units to accommodate the diversity. A
tool like questionnaire with predetermined questions need to be prepared, tried out on a
small sample and finalise the questions. Data may be collected from at least 30 units.
This number is suggested to apply statistical analysis for meaningful conclusions.
Guides may decide on the sample size depending on the accessibility of data.
22. The intention of the above three points viz., 19, 20 and 21 is to ensure objectivity in data
collection i.e., to reduce the subjectivity of the human mind.
23. All the above activities need to be completed before three to four weeks before the end of
V semester (refer the spread sheet related to scheduling).
24. The learners may be instructed to collect data objectively with identified sample during
the next 4 to six weeks which includes the mid semester holidays. This would enable the
learners to visit the field and collect data without the constraint of reporting to institution
and attending classes on a regular basis.
25. The collected data need to be organised and entered to spread sheets or similar formats
for analysis. Qualitative data may be converted to quantitative using a rating scale or
similar data organisation procedures.
26. The result of most analysis on spreadsheet could be obtained in tables or graphs as per the
requirement.
27. Activities mentioned in points 24, 25 and 26 may be carried out by learners during 4 to 8
weeks after commencement of VI semester.
130
28. Interpretation of the analysed tables and graphs to arrive at meaningful inference. The
guide at this stage may defer his ideas on interpretation allowing the learners to do this.
In case the learners err in the process they may be given corrective feedback.
29. A report of the whole process of doing the project may be written, word processed and
submitted in triplicate.
30. Guides may contact industries and try to solve their problems so that the learners get a
field experience and they get ready for the industry.
31. Innovations and innovative practices may be encouraged among the learners to be
pursued as a project. Developing prototypes, (in simulation or real) trying out feasibility
of new ideas, changing existing systems by adding modules, combining, assembling new
modules and developing new systems may be given higher priority over routine bookish
projects.
32. The schedule of events proposed is for an investigative project as a model. Guides may
alter the prescribed schedule to suit the kind of innovative projects sited in point No.31
above.
33. Industry personnel may be involved in conceiving, executing and evaluating projects.
This gives credibility to the institute and acceptance of learners for absorption into the
company.
GUIDELINES TO LEARNERS TO CARRY OUT A TWO SEMESTER PROJECT
1. Carry out the project work through the V and VI semesters. Preparation must be done
during the V semester and based on this, field work should be done during the mid
semester vacation and reporting of analysis and inferences should be done in the VI
semester.
2. You have the ability and the level of maturity needed to conceive an innovative and
meaningful project accomplishing which gives you recognition by the industry and
empowers you with the power of knowledge.
3. Understand your strength and weakness and make an effort to find the strength and
weakness of other peers in the team.
4. Complement each other‟s strength rather than compete with peers within the team. This
will enable you to complete a comprehensive and innovative project relevant to the
industrial needs rather than doing a routine copy of what others have done.
5. Seek guidance from the teacher and update him/her about the progress.
131
6. Be confident about your ability and that of other members of your group. Take extra
efforts to collect information, share with your peers and synthesise your knowledge.
7. Question everything including the ideas of your teacher. Accept the ideas and
instructions which are internally consistent (logical).
8. Involve actively in group activities and contribute towards the tasks.
9. Do not depend too much on the teacher as a source of information, search on your own
and build your knowledge structure. Search for authentic sources like journal articles,
books and authentic sites rather than blogs and tweets.
10. Though brief, record your thoughts and activities including searches immediately.
11. Prepare a schedule for your work on a spread sheet and encourage your peers to do the
same.
12. Show your schedule and that of others to the teacher and get his feedback.
13. Keep reviewing the schedule every fortnight and take corrective steps if needed. For
doing this keep the general guideline schedule given in the curriculum as a backdrop.
14. Tools used for data collection like instruments, testing machines, questions to be asked
and software may be tried out and standardised by the twelfth week of the project. Seek
the teacher‟s help who is experienced in doing this.
15. Collect data dispassionately or objectively (without applying your personal prejudice).
Complete this task before the VI semester begins.
16. While entering data into the spread sheet ask your peer member to verify. This will
ensure accuracy of data entry.
17. Use appropriate mathematics/statistics for calculations. Seek help from external sources
(other than your teacher) if required.
18. The results of your analysis need to be graphically represented and documented. You
may also add photographs and video clips to increase the validity.
19. This task needs to be completed within 8 weeks after commencement of VI semester.
20. Interpret the data (after analysis) and arrive at meaningful inferences on your own in
discussion with your peers. Get it ratified by your teacher. Suggestions from the teacher
may be discussed among your peers and incorporated if they are internally consistent.
21. The project report may be word processed (videos, photographs attached in soft copy)
and submitted in triplicate two weeks before the end of VI semester.
22. Involve passionately in the team work, make constructive contributions and come out
with an industry friendly project which will equip you in your professional development.
