Ανάλυση Συστημάτων βάσει Διαδικασιών – Process Oriented System Analysis

In Business, Engineering, IT on 20/05/2016 at 12:56 pm

DFD-Coad-and-Yourdon-Object-Oriented-Analysis-modelΗ δομημένη ανάλυση (και ο σχεδιασμός που έπεται), υπακούει στην αρχιτεκτονική έννοια «η φόρμα (form) ακολουθεί πάντα τη λειτουργία (function)». Οι  λειτουργίες ενός Πληροφοριακού Συστήματος (ΠΣ), είναι οι διαδικασίες που μετατρέπουν ή μετασχηματίζουν (transform) δεδομένα εφαρμογών. Ως εκ τούτου, στην δομημένη ανάλυση, δίνουμε έμφαση στις διαδικασίες (processes) και στις ροές δεδομένων (data flows), από και προς αυτές τις διαδικασίες.

Η δομημένη ανάλυση βασίζεται στην θεωρία συστημάτων, η οποία προϋποθέτει ότι τα εισερχόμενα δεδομένα (inputs) τροφοδοτούν τις διαδικασίες, προκειμένου αυτές να παράγουν εξερχόμενα δεδομένα (outputs). Για να συμπληρώσουμε το μοντέλο συστημάτων (παρακάτω σχήμα 1), θα πρέπει να υπάρχει και κάποιο είδος ανατροφοδότησης (feedback), προκειμένου να εξαλειφθεί η εντροπία του συστήματος, δηλαδή να εξασφαλίσουμε το σύστημα από έκπτωση.





Σχήμα 1 (Μοντέλο Συστημάτων)

Για να αναλύσουμε εννοιολογικά σύνθετα συστήματα όπως τα πληροφοριακά, αναλύουμε τμήματά τους μεμονωμένα. Μπορούμε δηλαδή να εξετάσουμε τα εισερχόμενα, εξερχόμενα και τις διαδικασίες ξεχωριστά και, μετά, όλα αυτά, να τα ολοκληρώσουμε για να παράγουμε ένα ενοποιημένο σύστημα. Καθώς οι διαδικασίες των συστημάτων γίνονται ολοένα πολυπλοκότερες, συνεχίζοντας με την ίδια μέθοδο, μελετάμε τμήματα των διαδικασιών αυτών και κατόπιν τα ολοκληρώνουμε. Τα τμήματα αυτά των διαδικασιών θα πρέπει να είναι αυτάρκη, μικρά συστήματα. Αυτά τα μικρότερα συστήματα αποτελούν μια ιεραρχία συστατικών συστημάτων (system components hierarchy), τέτοια ώστε, ένα συστατικό σε οποιοδήποτε επίπεδο να είναι από μόνο του ένα σύστημα με συστατικά. Κάθε σύστημα, ανεξαρτήτως επιπέδου στο οποίο βρίσκεται, έχει τα δικά του εισερχόμενα, εξερχόμενα και τις δικές του διαδικασίες και ανατροφοδότηση. Στο χαμηλότερο επίπεδο της ιεραρχίας είναι τα στοιχειώδη ή τερματικά συστατικά, τα οποία δεν μπορούν να διαιρεθούν περισσότερο και διατηρούν τα χαρακτηριστικά του συστήματός τους.

Digital and Social Media Marketing – The importance of ongoing monitoring (part VI)

ongoing monitoring#1 | Introduction

In this last chapter we are going to talk about the importance of monitoring and learning from your engagements. It is not surprising and it still does happen that businesses will go out to social media networks, spend a lot of money and at the end of the process have no idea whether they have been successful, or seen any benefit or actually any return on their investment. Campaigns do not work in isolation. Campaigns do need to be a part of a plan and that plan should necessitate that you learn from and reflect upon what information you can take from your buyer persona in relation to your content. All of your social media networks of significance provide feedback; provide data that can be used to improve, to modify and to change direction if necessary for a campaign. They can also be used to compare with others and they can also be used to understand what the buyer persona is responding to. All of this means that it is worth time and effort to analyze the data that is available to you possibly right now. There is a lot of data out there and ultimately it is the understanding of what social networks provide to you and being able to understand from the social networks what you need to do next.

The biggest focus of social media marketing is that we promote our solution online and we reach out consumer online. That is why this strategy is very important for us because we can analyze social marketing campaigns which we can order and assign to our team members and then we can analyze the effectiveness, the return on investment even with the smallest budget to reach the targeted people that we want and it is important to use those channels which work best.

A weekly meeting in the office is a good practice to make sure that you are reviewing activity quite regularly, it is important to review things quite a lot. In a new campaign that goes live you should tend to log in to new statistics every day but you can see a more full effect especially on overall traffic levels or organic search levels on a more longer term basis so you can have key statistics that you can pull from your online tools across the business on weekly basis and have that catch up in your marketing meeting which allows you to make decisions on whether you continue to invest in certain areas or invest in something new, and try something else because something is dropping off. I would say weekly is a good standpoint to have from a monitoring and evaluating point of view.

Monitoring is definitely an ongoing process. We could be having monthly reports for this process. First of all you could be asking from different departments responding from social media, reporting from websites, reporting from the campaign, from the planners’ part that is, and you could also have one project manager analyzing data and trying to find results from different platforms. One negative of digital advertising platforms is that they are not a lot of synergies between them. There are huge competitors like Facebook and Google so they are not allowing third parties to connect figures. What you have to do is take the results of different platforms and try to translate them in one report coming from you so that there is no golden rule or platform taking all in one and this is the worst thing online. When it is a PPC campaign you should do it every day, for SEO on a weekly basis and for content it is every hour because you have to see how competitors and funs are responding, and especially if you are using social media for customer service, you have to be there.

Digital and Social Media Marketing – Choosing the right digital profiles (part V)

In Business, IT on 11/04/2016 at 9:48 am

digital profile#1 | Introduction

We have already introduced the concept of the Buyer Persona (BP) and with the concept of our digital platform, we are really talking about the range of social media that we may already be familiar with and those that may come along in the future and those that we are less familiar with. All serve the same purpose for different BPs. What we are dealing with is different technologies, different purposes for these platforms and in those platforms different actions that are performed and are an opportunity to present to the BP.

Obviously, you have heard of Facebook, Tweeter, Snapchat and a range of others. All of which you might have experienced in some way. All these give an opportunity to reach out to the audience, to reach out to different BPs and to actually contact them in a way that is meaningful for them, meaningful for your brand and meaningful for the product. We are going to look at some of these in detail and look at what can be done to actually maximize the benefit of focusing the right BP to the right platform.

So we go about researching the right digital profiles for the right digital audiences by firstly having an understanding of the different sites, areas and platforms that exist and what they can offer for us. For example, LinkedIn is very different from Facebook and also very different from Twitter in terms of what it can offer, in terms of the right type of candidate for our business. We would speak to the websites themselves, look at the different offerings that they are able to give to us so that we can have an understanding of the type of candidate that would exist on those different areas.

You think that Facebook is better for ages 25-40; you think that search is better for ages 35+ but you only think. In digital you can measure. Sometimes you can see conversions coming from nowhere. So you have to see, test and revise.

The digital communication channel that many companies use with their customers is Facebook because it is the primary social media in the country, maybe Twitter, Instagram and Pinterest because their target group is mainly women for instance and YouTube because they are probably trying to get a younger set of customers. They also usually have email marketing in which they set out their weekly newsletters to registered clients and Google+ and Google Maps which give their clients more information for easily finding them.
