 Challenge 	
    I 	
   work 	
   at 	
   an 	
   advertising 	
   agency . 	
   The 	
   most 	
   of 	
   as 	
   are 	
   between 	
   20-­‐40 	
   years 	
   old , 	
   with 	
    approximately 	
   the 	
   same 	
   academic 	
   level 	
   and 	
   similar 	
   interest . 	
   Some 	
   of 	
   us 	
   are 	
   creative 	
    people , 	
   and 	
   others 	
   are 	
   account 	
   managers , 	
   so 	
   we 	
   have 	
   different 	
   points 	
   of 	
   view 	
   about 	
    how 	
   to 	
   approach 	
   each 	
   new 	
   campaign , 	
   and 	
   every 	
   one 	
   of 	
   us 	
   needs 	
   a 	
   different 	
   kind 	
   of 	
    information 	
   to 	
   develop 	
   our 	
   work . 	
   Our 	
   main 	
   client 	
   requieres 	
   quick 	
   responses 	
   because 	
    its 	
   market 	
   evolve 	
   very 	
   fast . 	
   This 	
   causes 	
   that 	
   we 	
   usually 	
   work 	
   in 	
   a 	
   hurry , 	
   and 	
   nobody 	
    knows 	
   what 	
   exactly 	
   the 	
   other 	
   people 	
   knows , 	
   so 	
   we 	
   get 	
   a 	
   lot 	
   of 	
   misunderstanding 	
    between 	
   us 	
   that 	
   cause 	
   a 	
   bad 	
   atmosphere 	
   at 	
   the 	
   agency . 	
  	
    I 'd 	
   like 	
   to 	
   reach 	
   any 	
   method 	
   or 	
   technique 	
   that 	
   help 	
   us 	
   to 	
   improve 	
   our 	
   information 	
   flow 	
    and , 	
   moreover , 	
   improve 	
   the 	
   atmosphere 	
   we 	
   are 	
   working 	
   in . 	
  	
   	
    Selection 	
    First 	
   of 	
   all , 	
   I 	
   realized 	
   that 	
   we 	
   had 	
   a 	
   problem 	
   that 	
   admit 	
   the 	
   application 	
   of 	
   Design 	
    Thinking , 	
   because 	
   we 	
   had 	
   no 	
   data 	
   about 	
   past 	
   moments 	
   and 	
   we 	
   had 	
   to 	
   make 	
   an 	
   effort 	
    to 	
   solve 	
   everyday 	
   problem , 	
   so 	
   we 	
   focused 	
   on 	
   the 	
   present . 	
   The 	
   tool 	
   we 	
   chose , 	
   after 	
    knowing 	
   deeply 	
   each 	
   other 	
   and 	
   listening 	
   carefully 	
   between 	
   us , 	
   was 	
   Learning 	
   Launch , 	
    because 	
   we 	
   agreed 	
   on 	
   a 	
   specific 	
   need : 	
   we 	
   require 	
   any 	
   kind 	
   of 	
   efficiency 	
   tool 	
   to 	
    manage 	
   information 	
   flow 	
   that 	
   keeps 	
   every 	
   one 	
   of 	
   us 	
   acquainted 	
   about 	
   all 	
   the 	
   projects . 	
  	
   	
    Application 	
    Asking 	
   for 	
   advice 	
   to 	
   friends 	
   from 	
   other 	
   agencies 	
   -­‐secondary 	
   research-­‐ , 	
   we 	
   discovered 	
    that 	
   they 	
   were 	
   using 	
   a 	
   tool 	
   they 	
   call 	
   ' status ' , 	
   that 	
   is 	
   an 	
   excel 	
   document 	
   with 	
    significative 	
   fields 	
   about 	
   people 	
   involved 	
   in 	
   each 	
   project , 	
   the 	
   different 	
   steps , 	
   the 	
   time 	
    it 	
   takes 	
   every 	
   step 	
   and 	
   the 	
   deadline 	
   before 	
   the 	
   project 	
   should 	
   be 	
   ended . 	
   So 	
   we 	
    develop 	
   our 	
   own 	
   ' status ' 	
   document , 	
   that 	
   involves 	
   those 	
   fields : 	
   Project 	
   / 	
   Account 	
    Manager 	
   / 	
   Creative 	
   team 	
   members 	
   / 	
   State 	
   of 	
   affairs 	
   / 	
   Deadline . 	
   And 	
   we 	
   proceed 	
   to 	
    test 	
   it 	
   in 	
   order 	
   to 	
   see 	
   if 	
   it 	
   worked . 	
  	
   	
    On 	
   monday , 	
   we 	
   had 	
   a 	
   meeting 	
   in 	
   to 	
   talk 	
   each 	
   other 	
   about 	
   which 	
   was 	
   our 	
   actual 	
    working 	
   situation , 	
   and 	
   after 	
   that 	
   we 	
   completed 	
   the 	
   sheet . 	
   Every 	
   single 	
   person 	
   at 	
   the 	
    agency 	
   received 	
   their 	
   copy 	
   of 	
   that 	
   sheet , 	
   so 	
   everyone 	
   can 	
   see 	
   at 	
   a 	
   glance 	
   what 	
   is 	
   the 	
    big 	
   picture 	
   of 	
   the 	
   agency . 	
   We 	
   spent 	
   a 	
   week 	
   working 	
   with 	
   the 	
   help 	
   of 	
   that 	
   tool , 	
   but 	
   we 	
    realized 	
   that 	
   we 	
   have n't 	
   consider 	
   the 	
   ' client 	
   feedback 	
   episodes ' , 	
   that 	
   should 	
   be 	
    displayed 	
   on 	
   the 	
   document , 	
   because 	
   when 	
   the 	
   client 	
   rejects 	
   a 	
   job , 	
   this 	
   job 	
   comes 	
   back 	
    to 	
   as 	
   and 	
   we 	
   need 	
   to 	
   rework , 	
   while 	
   we 	
   are 	
   working 	
   on 	
   other 	
   projects . 	
   What 	
   could 	
   we 	
    do ? 	
   Add 	
   a 	
   new 	
   job 	
   field ? 	
   Avoid 	
   that 	
   question 	
   till 	
   the 	
   next 	
   meeting ? 	
   	
  	
    We 	
   had 	
   to 	
   stop 	
   the 	
   experiment 	
   and 	
   modify 	
   our 	
   ' status ' 	
   sheet . 	
   We 	
   decided 	
   to 	
   add 	
   a 	
    new 	
   field : 	
   Client 	
   OK . 	
   So 	
   we 	
   could 	
   know 	
   if 	
   we 	
   need 	
   to 	
   rework 	
   on 	
   it . 	
   But ... 	
   things 	
    changes 	
   very 	
   quickly , 	
   so 	
   it 's 	
   enough 	
   to 	
   meet 	
   once 	
   a 	
   week 	
   to 	
   have 	
   our 	
   sheet 	
   updated ? 	
    No . 	
   So 	
   we 	
   decided 	
   to 	
   set 	
   a 	
   little 	
   meeting 	
   every 	
   day : 	
   a 	
   coffee 	
   pause 	
   to 	
   talk 	
   about 	
    changes , 	
   only 	
   for 	
   introducing 	
   information 	
   in 	
   the 	
   sheet 	
   about 	
   changes . 

 After 	
   that , 	
   we 	
   found 	
   another 	
   problem : 	
   our 	
   sheet 	
   was 	
   perfect 	
   and 	
   contained 	
   a 	
   lot 	
   of 	
    information 	
   but ... 	
   How 	
   could 	
   we 	
   know 	
   what 	
   is 	
   more 	
   important ? 	
   At 	
   this 	
   moment 	
   we 	
    decided 	
   to 	
   add 	
   a 	
   traffic-­‐light-­‐color-­‐system : 	
   red 	
   for 	
   urgent 	
   works ; 	
   yellow 	
   for 	
   mid 	
    importance 	
   works ; 	
   and 	
   green 	
   non 	
   priority 	
   works . 	
   Of 	
   course , 	
   the 	
   color 	
   status 	
   of 	
   a 	
    project 	
   had 	
   to 	
   change 	
   and 	
   evolve 	
   from 	
   green 	
   to 	
   red 	
   during 	
   the 	
   week : 	
   another 	
   task 	
   to 	
    do 	
   at 	
   coffee 	
   time ... 	
   Ok , 	
   too 	
   many 	
   meetings 	
   for 	
   us , 	
   specially 	
   when 	
   we 	
   are 	
   on 	
   a 	
    hurry . 	
   Finally 	
   we 	
   decided 	
   to 	
   appoint 	
   a 	
   manager 	
   for 	
   status 	
   sheet : 	
   a 	
   person 	
   who 	
   could 	
    spent 	
   an 	
   hour 	
   every 	
   monday 	
   and 	
   15 	
   minutes 	
   every 	
   day 	
   to 	
   update 	
   the 	
   status 	
   sheet . 	
   Of 	
    course , 	
   the 	
   manager 	
   it 's 	
   me , 	
   the 	
   planner . 

 As 	
   we 	
   can 	
   see 	
   on 	
   Learning 	
   Launches 	
   video , 	
   we 	
   decided 	
   to 	
   test 	
   a 	
   cheap 	
   and 	
   convenient 	
    time 	
   managing 	
   tool 	
   as 	
   soon 	
   we 	
   could . 	
   We 	
   could 	
   invest 	
   in 	
   some 	
   kind 	
   of 	
   productivity 	
    software , 	
   and 	
   spent 	
   many 	
   time 	
   and 	
   resources 	
   on 	
   training 	
   every 	
   single 	
   employee 	
   to 	
   use 	
    it , 	
   with 	
   no 	
   guarantee 	
   of 	
   success . 	
   By 	
   less 	
   price , 	
   we 	
   achieve 	
   an 	
   efficient 	
   self 	
   made 	
   tool 	
    that 	
   we 	
   can 	
   evolve 	
   ourselves 	
   every 	
   time 	
   we 	
   need 	
   in 	
   order 	
   it 	
   fits 	
   our 	
   desires . 	
  	
   	
  	
    Insight 	
    We 	
   discovered 	
   and 	
   learn 	
   a 	
   lot 	
   about 	
   ourselves 	
   and 	
   our 	
   ways 	
   of 	
   working , 	
   and 	
   now 	
   we 	
    have 	
   to 	
   admit 	
   a 	
   lot 	
   of 	
   mistakes 	
   that 	
   we 	
   have 	
   made 	
   during 	
   a 	
   long 	
   time 	
   before 	
   we 	
   tried 	
    to 	
   improve 	
   our 	
   working 	
   process . 	
   We 	
   had 	
   a 	
   narrow 	
   view 	
   of 	
   the 	
   processes 	
   because 	
   we 	
    only 	
   knew 	
   the 	
   things 	
   that 	
   every 	
   one 	
   of 	
   us 	
   were 	
   working 	
   in , 	
   and 	
   we 	
   were 	
   defending 	
    different 	
   ways 	
   of 	
   solving 	
   problems 	
   instead 	
   find 	
   a 	
   new 	
   path 	
   between 	
   everybody . 	
   It 	
   was 	
    also 	
   very 	
   helpful 	
   to 	
   listen 	
   to 	
   people 	
   from 	
   other 	
   agencies . 	
   Listening , 	
   definitely , 	
   was 	
   the 	
    correct 	
   answer . 	
   It 	
   was 	
   very 	
   inspiring 	
   for 	
   me 	
   the 	
   Good 	
   Kitchen 	
   case , 	
   because 	
   it 	
    portrayes 	
   the 	
   meaning 	
   of 	
   listen 	
   to 	
   the 	
   people 	
   that 	
   is 	
   involved 	
   in 	
   your 	
   very 	
   own 	
    problems , 	
   when 	
   you 	
   thing 	
   ( wrongly ) 	
   that 	
   you ’re 	
   alone . 	
  	
   	
    Approach 	
    Next 	
   time 	
   we 	
   could 	
   invest 	
   more 	
   time 	
   in 	
   testing 	
   more 	
   than 	
   one 	
   hypothesis , 	
   as 	
   long 	
   that 	
    it 	
   were 	
   as 	
   cheap 	
   as 	
   the 	
   one 	
   we 	
   developed . 	
   I 	
   think 	
   we 	
   settled 	
   very 	
   son , 	
   in 	
   spite 	
   of 	
   Lawan 	
   and 	
   Wolff 	
   advice . 	
   Our 	
   tool 	
   is 	
   nice 	
   but , 	
   could 	
   it 	
   be 	
   different , 	
   easier 	
   and 	
    even 	
   better ?

   what 	
   is 	
   the 	
    big 	
   picture 	
   of 	
   the 	
   agency . 	
   We 	
   spent 	
   a 	
   week 	
   working 	
   with 	
   the 	
   help 	
   of 	
   that 	
   tool , 	
   but 	
   we 	
    realized 	
   that 	
   we 	
   have n't 	
   consider 	
   the 	
   ' client 	
   feedback 	
   episodes ' , 	
   that 	
   should 	
   be 	
    displayed 	
   on 	
   the 	
   document , 	
   because 	
   when 	
   the 	
   client 	
   rejects 	
   a 	
   job , 	
   this 	
   job 	
   comes 	
   back 	
    to 	
   as 	
   and 	
   we 	
   need 	
   to 	
   rework , 	
   while 	
   we 	
   are 	
   working 	
   on 	
   other 	
   projects . 	
   What 	
   could 	
   we 	
    do ? 	
   Add 	
   a 	
   new 	
   job 	
   field ? 	
   Avoid 	
   that 	
   question 	
   till 	
   the 	
   next 	
   meeting ? 	
   	
  	
    We 	
   had 	
   to 	
   stop 	
   the 	
   experiment 	
   and 	
   modify 	
   our 	
   ' status ' 	
   sheet . 	
   We 	
   decided 	
   to 	
   add 	
   a 	
    new 	
   field : 	
   Client 	
   OK . 	
   So 	
   we 	
   could 	
   know 	
   if 	
   we 	
   need 	
   to 	
   rework 	
   on 	
   it . 	
   But ... 	
   things 	
    changes 	
   very 	
   quickly , 	
   so 	
   it 's 	
   enough 	
   to 	
   meet 	
   once 	
   a 	
   week 	
   to 	
   have 	
   our 	
   sheet 	
   updated ? 	
    No . 	
   So 	
   we 	
   decided 	
   to 	
   set 	
   a 	
   little 	
   meeting 	
   every 	
   day : 	
   a 	
   coffee 	
   pause 	
   to 	
   talk 	
   about 	
    changes , 	
   only 	
   for 	
   introducing 	
   information 	
   in 	
   the 	
   sheet 	
   about 	
   changes . 

 After 	
   that , 	
   we 	
   found 	
   another 	
   problem : 	
   our 	
   sheet 	
   was 	
   perfect 	
   and 	
   contained 	
   a 	
   lot 	
   of 	
    information 	
   but ... 	
   How 	
   could 	
   we 	
   know 	
   what 	
   is 	
   more 	
   important ? 	
   At 	
   this 	
   moment 	
   we 	
    decided 	
   to 	
   add 	
   a 	
   traffic-­‐light-­‐color-­‐system : 	
   red 	
   for 	
   urgent 	
   works ; 	
   yellow 	
   for 	
   mid 	
    importance 	
   works ; 	
   and 	
   green 	
   non 	
   priority 	
   works . 	
   Of 	
   course , 	
   the 	
   color 	
   status 	
   of 	
   a 	
    project 	
   had 	
   to 	
   change 	
   and 	
   evolve 	
   from 	
   green 	
   to 	
   red 	
   during 	
   the 	
   week : 	
   another 	
   task 	
   to 	
    do 	
   at 	
   coffee 	
   time ... 	
   Ok , 	
   too 	
   many 	
   meetings 	
   for 	
   us , 	
   specially 	
   when 	
   we 	
   are 	
   on 	
   a 	
    hurry . 	
   Finally 	
   we 	
   decided 	
   to 	
   appoint 	
   a 	
   manager 	
   for 	
   status 	
   sheet : 	
   a 	
   person 	
   who 	
   could 	
    spent 	
   an 	
   hour 	
   every 	
   monday 	
   and 	
   15 	
   minutes 	
   every 	
   day 	
   to 	
   update 	
   the 	
   status 	
   sheet . 	
   Of 	
    course , 	
   the 	
   manager 	
   it 's 	
   me , 	
   the 	
   planner . 

 As 	
   we 	
   can 	
   see 	
   on 	
   Learning 	
   Launches 	
   video , 	
   we 	
   decided 	
   to 	
   test 	
   a 	
   cheap 	
   and 	
   convenient 	
    time 	
   managing 	
   tool 	
   as 	
   soon 	
   we 	
   could . 	
   We 	
   could 	
   invest 	
   in 	
   some 	
   kind 	
   of 	
   productivity 	
    software , 	
   and 	
   spent 	
   many 	
   time 	
   and 	
   resources 	
   on 	
   training 	
   every 	
   single 	
   employee 	
   to 	
   use 	
    it , 	
   with 	
   no 	
   guarantee 	
   of 	
   success . 	
   By 	
   less 	
   price , 	
   we 	
   achieve 	
   an 	
   efficient 	
   self 	
   made 	
   tool 	
    that 	
   we 	
   can 	
   evolve 	
   ourselves 	
   every 	
   time 	
   we 	
   need 	
   in 	
   order 	
   it 	
   fits 	
   our 	
   desires . 	
  	
   	
  	
    Insight 	
    We 	
   discovered 	
   and 	
   learn 	
   a 	
   lot 	
   about 	
   ourselves 	
   and 	
   our 	
   ways 	
   of 	
   working , 	
   and 	
   now 	
   we 	
    have 	
   to 	
   admit 	
   a 	
   lot 	
   of 	
   mistakes 	
   that 	
   we 	
   have 	
   made 	
   during 	
   a 	
   long 	
   time 	
   before 	
   we 	
   tried 	
    to 	
   improve 	
   our 	
   working 	
   process . 	
   We 	
   had 	
   a 	
   narrow 	
   view 	
   of 	
   the 	
   processes 	
   because 	
   we 	
    only 	
   knew 	
   the 	
   things 	
   that 	
   every 	
   one 	
   of 	
   us 	
   were 	
   working 	
   in , 	
   and 	
   we 	
   were 	
   defending 	
    different 	
   ways 	
   of 	
   solving 	
   problems 	
   instead 	
   find 	
   a 	
   new 	
   path 	
   between 	
   everybody . 	
   It 	
   was 	
    also 	
   very 	
   helpful 	
   to 	
   listen 	
   to 	
   people 	
   from 	
   other 	
   agencies . 	
   Listening , 	
   definitely , 	
   was 	
   the 	
    correct 	
   answer . 	
   It 	
   was 	
   very 	
   inspiring 	
   for 	
   me 	
   the 	
   Good 	
   Kitchen 	
   case , 	
   because 	
   it 	
    portrayes 	
   the 	
   meaning 	
   of 	
   listen 	
   to 	
   the 	
   people 	
   that 	
   is 	
   involved 	
   in 	
   your 	
   very 	
   own 	
    problems , 	
   when 	
   you 	
   thing 	
   ( wrongly ) 	
   that 	
   you ’re 	
   alone . 	
  	
   	
    Approach 	
    Next 	
   time 	
   we 	
   could 	
   invest 	
   more 	
   time 	
   in 	
   testing 	
   more 	
   than 	
   one 	
   hypothesis , 	
   as 	
   long 	
   that 	
    it 	
   were 	
   as 	
   cheap 	
   as 	
   the 	
   one 	
   we 	
   developed . 	
   I 	
   think 	
   we 	
   settled 	
   very 	
   son , 	
   in 	
   spite 	
   of 	
   Lawan 	
   and 	
   Wolff 	
   advice . 	
   Our 	
   tool 	
   is 	
   nice 	
   but , 	
   could 	
   it 	
   be 	
   different , 	
   easier 	
   and 	
    even 	
   better ?
