System development lifecycle activites

Ruby
1

Hi,

I’ve been reading about the sdlc activites and I’d like to compose a
short list of things to do when starting a new app. I just wanted to ask
in general what you guys are using to design a new app. I guess it
applies “to each his own” when it comes to personal preferences, but
still…

I’d like to come up with a concise template for each iteration in sdlc
to minimize the documentation but covering all the bases.

kind regards,
seba

What do you mean by “app”?

What do you mean by “app”?

I mean an app or a computer program of a scope that would require
something like that. Obviously a small script would not fall in that
category, but something more complex like a project managament system.

Meanwhile, I found the something similar to what I had in mind here:

I hope you do notice that this is self referential. :slight_smile:

OK, so you are talking about applications written in Ruby. I had
asked because from your original posting it was not entirely clear to
me that you do not mean smartphone apps.

That is something generic as far as I can see. What people do
individually will typically depend on

  • the environment (company, team, project)
  • type of application
  • whether it is a product or custom build for a single customer or a
    few customers
  • even personal preferences

Kind regards

Probably the singular most important question to ask.

Hi Seba,

We use the IF4IT SDLC (located at:
http://www.if4it.com/SYNTHESIZED/FRAMEWORKS/SDLC/sdlc_framework.html )
because it covers and separates phases with actual environments. This
allows us to automate the Deployment Functions that get executed in each
environment…

  • Build
  • Package
  • Distribute
  • Install
  • Instantiate
  • Initialize
  • Execute/Run (and Test)

As far as tests that can be automated…

Deployment Testing

  • Build Verification Tests
  • Packaging Verification Tests
  • Distribution Verification Tests
  • Installation Verification Tests
  • Instantiation Verification Tests
  • Initialization Verification Tests
  • Execution Verification Tests (Which directly tie to each of the types
    of the General Test Types, listed below…)

General Testing

  • All Unit & Module Tests
  • All Systems Integration Tests
  • All Performance Tests
  • Most User Acceptance Tests
  • Most Security Penetration Tests
  • Disaster Recovery Tests

The automation of the above is tied directly into our Continuous Build &
Integration Framework (CBIF) that pretty much runs on demand (any time a
change is implemented in an environment).

We layer an Agile-like approach over the SDLC, where we run things
through the SDLC in small groups of changes so we can move things as far
and as fast through the pipeline as possible. And, we use Project Plans
that account for all work in every SDLC Phase. Since the Phase layout
is repeatable, the Project Plans make for highly repeatable templates
that can be reused for most Projects, minimizing having to recreate new
plans from scratch.

I hope this helps.

I’ve only just realized why “app” was confusing, I’m sorry for that

I know it’s generic, I’ve just referenced it as an example. I agree with
your statement above and I’ll make my own activites templates.

Thank you for your time.
