  5. Session  Inputs   Recap:  Introduction  to  Software  Engineering   “The  establishment  and  use  of  sound  engineering  principles  in  order  to  obtain   economically  developed  software  that  is  reliable  and  works  efficiently  on  real   machines”   -­‐ Fritz  Bauer   (very  first  definition  of  software  engineering  in  1968)   Suggested  Activity:    MATCH  THE  CHITS Divide  the  learners  into  6  groups  where  10  students  will  be  in  each  group.  Write  the   following  areas  in  some  chits  and  the  development  methodologies  in  some  chits.  Shuffle   the  chits  and  provide  them  to  each  group.  Also  give  them  a  chart.  Ask  the  groups  to   exactly  match  and  stick  the  chits  on  the  chart.     The  following  are  the  sample  areas  and  its  development  methodologies:     1.  Bridge  –  Conventional  Engineering.   2.  Library  System  -­‐  Program   3.  Building  of  SRMCEM  –  conventional  Engineering   4.  Our  Transport  -­‐  Conventional  Engineering   5.  Matlab  –  Software  Engineering   6.  ERP  of  SRMCEM  –  Software  Engineering   7.  LKO-­‐FZB  Highway-­‐  Conventional  Engineering   8.  Lucknow  SGPGI-­‐  Conventional  Engineering   9.  Website  of  GBTU-­‐  Software  Engineering   10.  GPU-­‐  Conventional  Engineering   11.  Apple  iPad2-­‐  Conventional  Engineering   12.  Android  Honey  Comb-­‐  Software  Engineering     Give  them  5  minutes  to  stick  and  provide  the  answer.  Correct  the  incorrect  answer(s)  by   telling  the  reason. Software   Engineering   is   the   design,   development,   and   documentation   of   software   by   applying   technologies   and   practices   from   computer   science,   project   management,   engineering,   application   domains,   interface   design,   digital  asset  management  and  other  fields.

  6. Software  Development  Life  Cycle   Learners  will  be  able  to  learn  about,  software  development  life  cycle  (SDLC),  its   phases:   Plan/Requirements/Analyze/Design/Verify   Validate/Execute   etc.   with   respect  to  the  different  phases  while  planning  a  picnic.   Suggested  Activity:    ANALOGY Faculty:  “Let’s  go  for  a  picnic.  For  organizing  a  successful  picnic  one  has  to  take  care  of  all   the  prerequisites.  For  a  picnic  to  be  successful,  It  has  to  be  Feasible.     Its  requirement  should  be  properly  known.   It  should  be  properly  planned.   It  should  be  executed  well.”   Initially  there  is  a  problem  statement,     “A  group  of  learners  wants  to  go  for  a  picnic,  in  the  lakeside  on  a  weekend.  Also,  the   picnic  should  be  within  50  KM  from  the  city  limits,  there  should  be  proper  transportation   for  the  place,  the  time  duration  should  be  08  AM  to  06  PM,  there  should  be  music  /   dance/  games  for  the  learners,  there  should  be  lunch/  snacks  for  the  learners  and  the   picnic  should  not  cost  >  Rs.750/-­‐  per  head.”   Check  for  the  feasibility  of  going  to  the  picnic  with  respect  to  the  boundaries  specified.   The  problem  in  hand  is  logistically  huge  and  for  effectively  solving  the  problem  it  has  to   be   broken   into   small   manageable   pieces.   Then   according   to   the   credentials   and   capabilities  of  the  learners  in  the  group  the  smaller  tasks  should  be  distributed  among   them.   In  addition  there  should  be  a  group  leader/  manager  who  will  distribute  the  tasks  and  see   the  overall  progress.   1.Decide  how  many  people  want  to  go  for  the  picnic?   2.What  should  be  the  location  of  the  picnic?  Check  for  50  KM  boundary   3.Who  will  arrange  for  the  transportation?   4.Who  will  arrange  for  the  food?   5.Who  will  arrange  for  the  fun  bits  i.e.  dance/music/games.?   6.Who  will  collect  money?  Check  for  the  limit  of  Rs.  750/-­‐?   7.Who  will  check  for  the  overall  progress?   8.Who  will  look  for  the  permissions  for  the  lakeside  etc.?     SDLC MODEL Dr Qaim Mehdi Rizvi SRMCEM, Lucknow Page 5

  7. The  above  points  refers  to  a  process     Feasibility-­‐>Analysis-­‐>Requirement  Gathering-­‐>Design-­‐>Implement-­‐>Test       This  process  is  similar  to  how  software  is  designed  &  coded.  The  step  by  step  process  of   planning,  analyzing,  designing,  testing  and  coding  of  software  within  a  set  of  rules  and   parameters  is  called  Software  Development  Life  Cycle  (SDLC). The  step  by  step  process  of  planning,  analyzing,  designing,  testing  and  coding   of   software   within   a   set   of   rules   and   parameters   is   called   Software   Development  Life  Cycle  (SDLC).   Types  of  SDLC  Model   Learners   will   be   told   about   various   popular   SDLC   models   with   the   help   of   relevant  figures  and  illustrations  about  their  mechanism.   Suggested  Activity:    DEMONSTRATION  THROUGH   PPT   The  Software  Development  Life  Cycle  (SDLC)  Process  is  a  repeatable,  predictable  process  intended  to  improve   project  productivity  and  system  quality  and  to  enhance  the  management  of  a  computer  systems  project.  SDLC  for   software  engineering  is  chosen  based  on  the  nature  of  the  project  and  application,  the  methods  and  tools  to  be   used,  and  the  controls  and  deliverables  that  are  required.       Page 6 Ver : 1.02 SDLC MODEL Dr Qaim Mehdi Rizvi SRMCEM, Lucknow

  8.     General  SDLC  Model     Various  SDLC  models  are  available  and  these  are  used  according  to  the  need  and  nature  of  the  projects,  the   environmental  conditions,  and  the  available  time  frame  in  which  it  is  going  to  be  finished.  It  is  shown  here  with  its   working  structure.     SDLC MODEL Dr Qaim Mehdi Rizvi SRMCEM, Lucknow Page 7

  13. Selection  of  SDLC  Model  for  Mini  Projects   Students  should  able  to  understand  the  requirements  and  the  limitations  of   every   model.   By   critical   analysis   of   a   model,   it   is   more   feasible   to   develop   interest   in   next   proposed   approach   for   interacting   real   life   problems.   Mini   Projects  are  the  most  feasible  tools  for  improving  the  technical  skills  of  students   about  the  various  available  models.   Suggested  Activity:    Mini  Projects Divide  the  groups  into  some  groups  based  on  the  below  topics.  Assign  the  below  topics  to  each  group   and  ask  them  to  prepare  the  SDLC  phases  for  the  assigned  topic.  Finally  one  representative  from  each   group  will  be  called  to  narrate  their  preparation.  For  effective  involvement,  provide  them  some  charts   so  that  the  narration  would  be  very  easy  for  the  volunteer.     Some  sample  topics  from  the  various  wings  of  SRMCEM  would  be  as  follows:     1.Bus  Management  System   2.Hostel  Management  System   3.Mess  Management  System   4.Student  Management  System   5.Time-­‐Table  Management  System   The  structure  imposed  by  this  SDLC  is  specifically  designed  to  maximize  the   probability  of  a  successful  software  development.  But  user  requirements  vary   from   time   to   time.   That   is   why   software   development   is   not   like   only   constructing  a  building,  but  it  is  a  more  creative  process  than  that.   Conclusion   The  best  way  to  conclude  the  overall  session  is  to  check  the  knowledge  status  of   students  and  re-­‐brush  the  knowledge  in  an  interesting  way.   Page 12 Ver : 1.02 SDLC MODEL Dr Qaim Mehdi Rizvi SRMCEM, Lucknow

  14.
