| <h1> The bug statistics for NB3.2 and NB3.3</h1> |
| <br> |
| <b>PLEASE READ (at least) THIS:</B> I wanted to learn from NetBeans 3.2 stabilization |
| and try to predict how NB3.3 stabilization will be going. The first table shows numbers of bugs |
| during NB3.2 stabilization and the second table shows our current bugs statistics (7/13-8/17). |
| The numbers are not representing the same (NB3.2 counts only bugs reported for NB3.2 branch, |
| but NB3.3 table counts all opened bugs). |
| <br> |
| <h2>1. NetBeans 3.2 Stabilization<br> |
| </h2> |
| <br> |
| The first table shows the stabilization of NetBeans 3.2. Before stabilization |
| we had 592 bugs and when we released we had about 372 bugs. We resolved about |
| 1300 bugs but discovered about 1150 new. According to Honza Chalupa not all |
| bugs were included in this counts (because were reported for different branch). |
| So the numbers do not represent total number of opened bugs during stabilization.<br> |

| <h2>3. The observations</h2> |
| <ul> |
| <li><b>NetBeans 3.2 and NetBeans 3.3 are different</b>. Different schedule, |
| different features, etc. It is not so simple, just compare the numbers</li> |
| <li>It the <b>NB3.2 </b>table there are <b>not all bugs involved </b>(so |
| the total opened bugs numbers could be +200 or something like that). NetBeans |
| 3.3 numbers represent all currently opened bugs numbers.</li> |
| <li>It seems that:</li> |
| <ul> |
| <li>We are able to <b>resolve up to 150-200 bugs</b> <b>every week</b>.</li> |
| <li>A lot of new bugs were discovered during NB 3.2 stabilization: <b> |
| 1300 resolved vs. 1150 new</b>. </li> |
| <li>It will probably be <b>the same for NB3.3</b>.</li> |
| <li>Sun's QA spent <b>more or the same time </b><b>on NB3.2 compared |
| to NB3.3</b> during implementation phase (before feature freeze). So, we |
| can't say that for NB3.3 we have more bugs discovered in advance - before |
| feature freeze.</li> |
